Writing Accessible Web Content

Over on Sparkbox, Caralyn Green wrote a detailed article on what to think about when writing content for the web. The way we display copy, as well as the copy itself is probably one of the most overlooked aspects that contribute to a great, accessible user experience. From the post:

Trying to make sense of that site through sound only, I realized that the way our team had written and structured some of the content, including headings, links, and alt text, was not in fact accessible. So we did a full audit and reworked the content to make sure it was usable by as many people as possible.

Web Push Notification Tutorial

Over at the Microsoft Edge Demos playground they released a great tutorial walking you through all of the pieces that allows push notifications to work on the web. It is definitely well worth it. Although, I would definitely say that you should have the repo handy. From the tutorial:

Inspired by the parallels between basic astrological ideas and push notification architecture, come join us on this journey to better understand how to set up your site — both the front-end and the back-end — to send push messages to a user without needing the browser or app to be opened. You can fork this tutorial itself on GitHub and even set it up locally so that you can play with it.

Creating The Feature Queries Manager DevTools Extension

On Smashing Magazine Ire Aderinokun writes about the invaluable DevTools extension she wrote. The extension is called the Feature Query Manager, and allows you to easily simulate non-support of CSS features. Besides introducing us to the extension, she then walk you through the process of creating a DevTools extension. From the post:

The modern solution to developing for both modern and legacy browsers is feature queries. They allow us to write CSS that is conditional on browser support for a particular feature. Although working with feature queries is almost magical, testing them can be a pain. Unlike media queries, we can’t easily simulate the different states by just resizing the browser. That’s where the Feature Queries Manager comes in, an extension to DevTools to help you easily toggle your feature query conditions.

Talking about extensions. Over on the add-ons blog Mike Conca gives a thorough writeup on what’s new with regards to web extensions in Firefox 61.

Building a responsive image

On the 9 Elements Medium blog, Nils Binder writes a detailed write up on creating a responsive image. Now, this is not about using srcset, but how to do this with SVG, using what boils down to essentially container queries. From the post:

When you use media queries inside SVG files and then insert the image via img-tag or as a CSS background-image, the media queries are bound to the width of the image. Pretty much the same behavior as if you used Container Queries.

How to React

React is pretty much everywhere, and this alone is good reason to at least have an understanding of the framework. There is a lot to React, which means it can quickly become overwhelming when you are first trying to get your head around it all. If you need some guidance, Kent C. Dodds put together a great path you can follow to learn React in a more piecemeal, learn what you really need way.

Designing Web Content for watchOS

If you watched, or read the news from WWDC, you will know that webkit is coming to watchOS. This is a whole new form factor, with it’s own challenges and nuances. Over on Apple’s developer blog there is a really informative video explaining how to design for watchOS 5. From the post:

watchOS 5 brings web content to Apple Watch by rendering rich HTML in Messages and Mail. Gain insights into how watchOS maintains compatibility with existing web content, and find out what you can do to optimize your web content for Apple Watch.
