How to Design for Screen Readers with Adobe XD CC When it comes to accessibility, designers tend to focus on colors (i.e. contrast) and UX copy (i.e. wording), whereas developers tend to focus on ARIA attributes (i.e. code that makes websites more accessible). This is due to the fact that, often enough, thick lines are drawn between “who does what”. Also, because creating accessible apps and websites isn’t considered to be exciting, this line is hardly ever questioned. Accessibility is still a black sheep, even in 2020. So, since UX copy is the responsibility of the designer and ARIA attributes are the responsibility of the developer, exactly whose responsibility is it to cater for screen readers? Since: Screen reader UX copy is expressed as Braille or dictation (so how do we communicate this when our UI tools are visual?) Implementation is developer territory (so can we really shift the responsibility of writing UX copy to developers?) As you can see, it’s a two-person job — and yet, the tools simply don’t exist to facilitate this. I mean, make no mistake, some aspects of accessibility design are one-sided (for example, UI designers can very easily take care of color contrast by themselves). However, other aspects such as designing for screen readers requires collaboration between designers and developers. This is where Adobe XD CC’s design handoff and voice prototyping features come in handy. In this article, we’ll discuss what to consider when designing for screen readers, and we’ll also walk through how to use the features mentioned above. What Are Screen Readers? A screen reader is a type of assistive technology that communicates what’s happening on the screen (for those with visual impairments). Screen reader software can be used in combination with the keyboard (for example, users will tab and enter as opposed to using the mouse), but it can also be used in combination with screen reader hardware, which allows for more efficient navigation and also caters for users that use Braille. If you’re an Apple user, for example, you’ll be somewhat aware of Apple VoiceOver, which is the native Apple dictation software that acts as a screen reader. Windows users, however, commonly use either JAWS or NVDA, since there aren’t any native screen reader tools in the Windows operating system. Let’s dive in. 1. Use Headings Screen readers often use headings as a way of deciphering a website’s structure, and if we think too visually we run the risk of leaving out these headings. In the example below, the omission of the “Chapters” heading causes screen readers to assume that the list of chapters is a continuation of the content on the left-hand side, which it obviously isn’t. As a result, screen-reader users won’t be able to skip to “Chapters”, and they might not discover the information within. While there are code workarounds available (such as the aria-label attribute), having a visible heading inclusively offers a clearer experience for everybody, whether disabled or not. Of course, the section is very obviously a list of chapters, as we can infer from the context (i.e. the content). However, those using screen readers very rarely have the luxury of context. It’s like trying to find an object in storage where none of the boxes are labeled. Our designs need these labels and headings. On the technical side, the rule is that every section (as defined by a <section> or <article> tag) should have not only a heading, but an explicit heading that conflicts with no other heading. As an example, if the highest level heading within a section is an <h2>, then there should be no other <h2> heading within that section. Otherwise, screen readers are clueless as to which heading is the label for the section. The post How to Design for Screen Readers with Adobe XD CC appeared first on SitePoint. Feb 27 10 Ways to Hide Elements in CSS There are multiple ways to hide an element in CSS, but they differ in the way they affect accessibility, layout, animation, performance, and event handling. Animation Some CSS hiding options are all or nothing. The element is either fully visible or fully invisible and there’s no in-between state. Others, such as transparency, can have a range of values, so interpolated CSS animations become possible. Accessibility Each method described below will visually hide an element, but it may or may not hide the content from assistive technologies. For example, a screen reader could still announce tiny transparent text. Further CSS properties or ARIA attributes such as aria-hidden="true" may be necessary to describe the appropriate action. Be wary that animations can also cause disorientation, migraines, seizures, or other physical discomfort for some people. Consider using a prefers-reduced-motion media query to switch off animations when specified in user preferences. Event Handling Hiding will either stop events being triggered on that element or have no effect — that is, the element is not visible but can still be clicked or receive other user interactions. Performance After a browser loads and parses the HTML DOM and CSS object model, the page is rendered in three stages: Layout: generate the geometry and position of each element Paint: draw out the pixels for each element Composition: position element layers in the appropriate order An effect which only causes composition changes is noticeably smoother than those affecting layout. In some cases, the browser can also use hardware acceleration. 1. opacity and filter: opacity() The opacity: N and filter: opacity(N) properties can be passed a number between 0 and 1, or a percentage between 0% and 100% denoting fully transparent and fully opaque accordingly. See the Pen hide with opacity: 0 by SitePoint (@SitePoint) on CodePen. There’s little practical difference between the two in modern browsers, although filter should be used if multiple effects are applied at the same time (blur, contrast, grayscale etc.) Opacity can be animated and offers great performance, but be wary that a fully transparent element remains on the page and can trigger events. metric effect browser support good, but IE only supports opacity 0 to 1 accessibility content not read if 0 or 0% is set layout affected? no rendering required composition performance best, can use hardware acceleration animation frames possible? yes events triggered when hidden? yes 2. color Alpha Transparency opacity affects the whole element, but it's also possible to set the color, background-color, and border-color properties separately. Applying a zero alpha channel using rgba(0,0,0,0) or similar renders an item fully transparent: See the Pen hide with color alpha by SitePoint (@SitePoint) on CodePen. Each property can be animated separately to create interesting effects. Note that transparency can’t be applied to elements with image backgrounds unless they're generated using linear-gradient or similar. The alpha channel can be set with: transparent: fully transparent (in-between animations are not possible) rgba(r, g, b, a): red, green, blue, and alpha hsla(h, s, l, a): hue, saturation, lightness, and alpha #RRGGBBAA and #RGBA metric effect browser support good, but IE only supports transparent and rgba accessibility content still read layout affected? no rendering required painting performance good, but not as fast as opacity animation frames possible? yes events triggered when hidden? yes 3. transform The transform property can be used to translate (move), scale, rotate, or skew an element. A scale(0) or translate(-999px, 0px) off-screen will hide the element: See the Pen hide with transform: scale(0); by SitePoint (@SitePoint) on CodePen. transform offers excellent performance and hardware acceleration because the element is effectively moved into a separate layer and can be animated in 2D or 3D. The original layout space remains as is, but no events will be triggered by a fully hidden element. metric effect browser support good accessibility content still read layout affected? no — the original dimensions remain rendering required composition performance best, can use hardware acceleration animation frames possible? yes events triggered when hidden? no The post 10 Ways to Hide Elements in CSS appeared first on SitePoint. Feb 26 How to Prepare for a Remote Job Search The number of people working remotely is at an all-time high, and that’s not just because telecommuting is pants-optional. By giving employees more control over their schedule and work environment, remote jobs can enhance the work-life balance that so many people struggle to maintain. But if you’ve held in-house positions for most of your career, properly preparing for your remote job search can up your chances of impressing remote employers, nailing the interview, and landing a remote job that best fits your needs. What Are Remote Employers Looking For? Remote employers are looking for three things in particular. Independence The office may at times feel like a panopticonic prison, but there is something to be said for workplace accountability. Can you stay focused without a boss periodically checking in on you? Can you stay productive without the sight and sound of other co-workers clacking away on their computers? When you work from home, the Damocles of the deadline is blunted and the motivating effect of being in close proximity to your team members weakens. Remote employers understand these challenges, which is why they look for candidates who can motivate themselves without external prompting. As trite as buzzwords like self-starter and proactive can be, they carry a significant amount of weight in the remote job search. Not only do you need to possess these qualities, you’ll need to be able demonstrate them to potential employers. Communication Working in an office allows employees to be more passive. Don’t know what’s going on? A co-worker can fill you in via a few seconds of conversation. Your boss is only a few steps away. Maybe there’s a whiteboard in the break room with announcements. Sharing a space with people just makes it much easier to stay in the loop. But if you’re on your own, you need to take initiative. To compensate for the lack of face-to-face, a good remote worker will put effort into the virtual communication tools at their disposal. They’ll reach out to people through email or Slack. They’ll suggest video chats or calls to hash things out. Even swapping memes in a group chat can help you stay engaged. But if you give in to the temptation of solitude, communication could suffer, and so could your work. Rational Thinking When communicating primarily through text, it’s all too common for our imaginations to run wild with unfounded anxieties. Emailed your boss a question and they didn’t respond within whatever time frame you’ve arbitrarily decided was reasonable? They must think it’s a dumb question and you’re dumb for asking it. They must not deem you important enough to expediently respond to. They must be offended by something you wrote. Asked a co-worker to do something and they responded with “k”? They hate you. They’re telling everyone how much they hate you. Everyone hates you. You’re garbage! Or … absolutely none of that is true and the coldness of non-verbal communication is messing with your head. Like any good employer, remote employers don’t want drama. They want rational critical thinkers who can vault the pitfalls of remote communication and maintain healthy work relationships. K? How Do You Demonstrate These Skills On Your Resume? Even if you have little to no remote work experience, there are ways to frame your in-house work experience so that it demonstrates remote work skills. What have you done that demonstrates independence? Communication? Rational thinking? Figure it out and integrate it into your resume. For example, if you took the initiative on anything in a previous position, emphasize it. Say you independently devised and implemented project x or volunteered to plan, create, and maintain project y. Explain that you created and ran program z with little oversight. Here are some other ideas to get you thinking: The post How to Prepare for a Remote Job Search appeared first on SitePoint. Feb 25 Build a Simple Beginner App with Node, Bootstrap and MongoDB If you’re just getting started with Node.js and want to try your hand at building a web app, things can often get a little overwhelming. Once you get beyond the “Hello, World!” tutorials, much of the material out there has you copy-pasting code, with little or no explanation as to what you’re doing or why. This means that, by the time you’ve finished, you’ve built something nice and shiny, but you also have relatively few takeaways that you can apply to your next project. In this tutorial, I’m going to take a slightly different approach. Starting from the ground up, I’ll demonstrate how to build a no-frills web app using Node.js, but instead of focusing on the end result, I’ll focus on a range of things you’re likely to encounter when building a real-world app. These include routing, templating, dealing with forms, interacting with a database and even basic authentication. This won’t be a JavaScript 101. If that’s the kind of thing you’re after, look here. It will, however, be suitable for those people who feel reasonably confident with the JavaScript language, and who are looking to take their first steps in Node.js. What We’ll Be Building We’ll be using Node.js and the Express framework to build a simple registration form with basic validation, which persists its data to a MongoDB database. We’ll add a view to list successful registration, which we’ll protect with basic HTTP authentication, and we’ll use Bootstrap to add some styling. The tutorial is structured so that you can follow along step by step. However, if you’d like to jump ahead and see the end result, the code for this tutorial is also available on GitHub. Basic Setup Before we can start coding, we’ll need to get Node, npm and MongoDB installed on our machines. I won’t go into depth on the various installation instructions, but if you have any trouble getting set up, please visit our forums and ask for help there. Node.js Many websites will recommend that you head to the official Node download page and grab the Node binaries for your system. While that works, I would suggest that you use a version manager instead. This is a program which allows you to install multiple versions of Node and switch between them at will. There are various advantages to using a version manager. For example, it negates potential permission issues which would otherwise see you installing packages with admin rights. If you fancy going the version manager route, please consult our quick tip: Install Multiple Versions of Node.js Using nvm. Otherwise, grab the correct binaries for your system from the link above and install those. npm npm is a JavaScript package manager which comes bundled with Node, so no extra installation is necessary here. We’ll be making quite extensive use of npm throughout this tutorial, so if you’re in need of a refresher, please consult A Beginner’s Guide to npm — the Node Package Manager. MongoDB MongoDB is a document database which stores data in flexible, JSON-like documents. If you’ve never worked with Mongo before, you might like to check out our beginner-friendly introduction to MongoDB. The quickest way to get up and running with Mongo is to use a service such as mLabs. They have a free sandbox plan which provides a single database with 0.5GB of storage running on a shared virtual machine. This is more than adequate for a simple app with a handful of users. If this sounds like the best option for you, please consult their quick-start guide. You can also install Mongo locally. To do this, please visit the official download page and download the correct version of the community server for your operating system. There’s a link to detailed, OS-specific installation instructions beneath every download link, which you can consult if you run into trouble. A MongoDB GUI Although not strictly necessary for following along with this tutorial, you might also like to install Compass, the official GUI for MongoDB. This tool helps you visualize and manipulate your data, allowing you to interact with documents with full CRUD functionality. Check that Everything is Installed Correctly To check that Node and npm are installed correctly, open your terminal and type: node -v followed by: npm -v This will output the version number of each program (12.14.1 and 6.13.6 respectively at the time of writing). If you installed Mongo locally, you can check the version number using: mongo --version This should output a bunch of information, including the version number (4.2.2 at the time of writing). Check the Database Connection Using Compass If you’ve installed Mongo locally, you start the server by typing the following command into a terminal: mongod Next, open Compass. You should be able to accept the defaults (server: localhost, port: 27017), press the CONNECT button, and establish a connection to the database server. MongoDB Compass connected to localhost Note that the databases admin, config and local are created automatically. Using a Cloud-hosted Solution If you’re using mLabs, create a database subscription (as described in their quick-start guide), then make a note of the connection details. Open Compass, click New Connection, then Fill in connection fields individually. Select Username / Password as the authentication method, then fill out the rest of the details. Finally, click CONNECT and you should be off to the races. Note: if you wish to use a connection string, it should look like this: mongodb://<dbuser>:<dbpassword><dbname>. MongoDB Compass connected to mLabs Note that I called my database sp-node-article. You can call yours what you like. Initialize the Application With everything set up correctly, the first thing we need to do is initialize our new project. To do this, create a folder named demo-node-app, enter that directory and type the following in a terminal: npm init -y This will create and auto-populate a package.json file in the project root. We can use this file to specify our dependencies and to create various npm scripts, which will aid our development workflow. Install Express Express is a lightweight web application framework for Node.js, which provides us with a robust set of features for writing web apps. These features include such things as route handling, template engine integration and a middleware framework, which allows us to perform additional tasks on request and response objects. There’s nothing you can do in Express that you couldn’t do in plain Node.js, but using Express means we don’t have to re-invent the wheel and it reduces boilerplate. So let’s install Express. To do this, run the following in your terminal: npm install express This will see Express added to the dependencies section of the package.json file. This signals to anyone else running our code that Express is a package our app needs to function properly. Install nodemon nodemon is a convenience tool. It will watch the files in the directory it was started in, and if it detects any changes, it will automatically restart your Node application (meaning you don’t have to). In contrast to Express, nodemon is not something the app requires to function properly (it just aids us with development), so install it using: npm install --save-dev nodemon This will add nodemon to the dev-dependencies section of the package.json file. Create Some Initial Files We’re almost through with the setup. All we need to do now is create a couple of initial files before kicking off the app. In the demo-node-app folder create an app.js file and a start.js file. Also create a routes folder, with an index.js file inside. After you’re done, things should look like this: . ├── app.js ├── node_modules │ └── ... ├── package.json ├── package-lock.json ├── routes │ └── index.js └── start.js Now, let’s add some code to those files. In app.js: const express = require('express'); const routes = require('./routes/index'); const app = express(); app.use('/', routes); module.exports = app; Here, we’re importing both the express module and (the export value of) our routes file into the application. The require function we’re using to do this is a built-in Node function which imports an object from another file or module. If you’d like a refresher on importing and exporting modules, read Understanding module.exports and exports in Node.js. After that, we’re creating a new Express app using the express function and assigning it to an app variable. We then tell the app that, whenever it receives a request from forward slash anything, it should use the routes file. Finally, we export our app variable so that it can be imported and used in other files. In start.js: const app = require('./app'); const server = app.listen(3000, () => { console.log(`Express is running on port ${server.address().port}`); }); Here we’re importing the Express app we created in app.js. (Note that we can leave the .js off the file name in the require statement.) We then tell our app to listen on port 3000 for incoming connections and output a message to the terminal to indicate that the server is running. And in routes/index.js: const express = require('express'); const router = express.Router(); router.get('/', (req, res) => { res.send('It works!'); }); module.exports = router; Here, we’re importing Express into our routes file and then grabbing the router from it. We then use the router to respond to any requests to the root URL (in this case http://localhost:3000) with an “It works!” message. Kick off the App Finally, let’s add an npm script to make nodemon start watching our app. Change the scripts section of the package.json file to look like this: "scripts": { "watch": "nodemon ./start.js" }, The scripts property of the package.json file is extremely useful, as it lets you specify arbitrary scripts to run in different scenarios. This means that you don’t have to repeatedly type out long-winded commands with a difficult-to-remember syntax. If you’d like to find out more about what npm scripts can do, read Give Grunt the Boot! A Guide to Using npm as a Build Tool. Now, type npm run watch from the terminal and visit http://localhost:3000.

Feb 25 How to Properly Organize Files in Your Codebase & Avoid Mayhem The main library, data, UI, docs and wiki, tests, legacy and third-party components … How do we keep track and maintain order within all of this? Organizing the files in your codebase can become a daunting task. Relax — we've got this! In this article, we’ll review the most common systems for both small and large projects, with some easy-to-follow best practices. Why Bother? As with pretty much all of the tasks related to project management — documentation, software commits, deployment — you’ll benefit from taking a conscious, programmatic approach. Not only it will reduce problems now, but it will also save you and your team quality time in the future when you need to quickly access and review things. You surely can recall function names from the top of your head for whatever is it that you're coding right now, and quickly find a file you need to edit, and sharply tell what works from what doesn't — or so you think. But could you say the same about that project you were working on last year? Let's admit it: software projects can go on spans of inactivity that last for months, and even years. A simple README file could do a lot for your colleagues or your future self. But let's think about the other ways you could structure your project, and establish some basic rules to name files, address project documentation, and to some degree organize an effective workflow that would stand the test of time. Making Sense of Things We’ll establish a "baseline" for organizing files in a project — a logic that will serve us for a number of situations within the scope of software development. As with our rules for committing changes to your codebase the right way, none of this is carved in stone, and for what it's worth, you and your team might come up with different guidelines. In any case, consistency is the name of the game. Be sure you understand (and discuss or dispute) what the rules are, and follow them once you've reached a consensus. The Mandatory Set This is a reference list of files that nearly every software project should have: README: this is what GitHub renders for you right under the sourcetree, and it can go a long way to explaining what the project is about, how files are organized, and where to find further information. CHANGELOG: to list what's new, modified or discontinued on every version or revision — normally in a reverse chronological order for convenience (last changes first). COPYING LICENSE: a file containing the full text of the license covering the software, including some additional copyright information, if necessary (such as third-party licenses). .gitignore: assuming you use Git (you most probably do), this will also be a must to tell what files not to sync with the repository. (See Jump Start Git's primer on .gitignore and the documentation for more info, and have a look at a collection of useful .gitignore templates for some ideas.)

Feb 20 Productive Remote Work (When Your Mental Health Says “No”) Remote work is not easy. It sounds like a dream (and it honestly is in a lot of ways), but there’s a darker side to remote work that one can’t understand until they’ve done it. Here’s the deal. People that work remotely often suffer from suboptimal mental health, and so you’re probably wondering, why on earth do they do it? Well, the fact is, while remote working comes with some very unique challenges, so does not working remotely. The difference is that remote work can offer the flexibility you need to build a lifestyle that suits you. Indeed, remote work isn’t a silver bullet for burnout or wanderlust, but if you do happen to try it out and eventually wind up succumbing to loneliness, or a lack of motivation or productivity (as many remote workers do), at least you’ll have the opportunity to change things up and make things better. In the eyes of many, it’s the lesser of two evils. That being said, attempting to diagnose what your mind and body needs isn’t that easy. What might work one day might not work on another day, and what might work for one individual might not work for another individual. Humans are complex, and in the case of remote work, everyday productivity tricks often don’t cut it. Let’s take a look. “I feel lonely” Loneliness is a big issue (maybe the biggest?) for freelance remote workers and digital nomads in foreign countries, but it can also affect those that work in distributed teams (especially when some team members aren’t remote, as one can feel like an outsider at work using this setup). Let’s look at the solutions. Utilize co-working spaces Co-working spaces aren’t for everyone. If you teach English, it’s obviously a no-no (not because of the noise, but because the noise would be distracting to other remote workers). If you’re only required to dive into the odd video call, though, many co-working spaces include a few hours of “booth time”. Throw in super-fast Wi-Fi, free coffee, daily events, and a likeminded crowd, joining a co-working space is like joining a community, and some co-working spaces (such as Hubud) and Dojo Bali) are literally famous! Good vibes = a huge motivation boost. Work from bars and cafés Cafés and bars work well too. The noise and seating options might be a tad unpredictable, and when going to a new place one has to find the Wi-Fi password, but all in all the experience is very much the same. It’s still fairly easy to meet other people, as it’s likely that you won’t be the only regular customer. Pro-tip: download Wi-Fi Map app to get the Wi-Fi passwords of networks near you!
