How to Fail at Accessibility
So, let’s flip the script, and dive into — “How not to fail at accessibility”
We’re going to cover three main areas:
Testing — how do you know if your website is or is not accessible currently?
Building — once you’ve identified some bugs, how do you code for accessibility?
Process — how can you improve your process to prevent bugs in the first place?

Writing Tests For CSS Is Possible! Don’t Believe The Rumors, by Gil Tayar
You know that fear. The fear of changing something in your CSS. Deleting a CSS rule is a lesson in getting yourself to calm down, telling yourself that it’s OK, you are absolutely sure that deleting that rule won’t change anything.

And only manual testing can assuage that fear. And yet, even then, you’re still frightened that you haven’t checked _everything_, and that you missed something. Not to mention that it’s amazingly boring.

Never fear again! Testing your CSS code, testing the visual aspects of your code, is now possible, and I will show how. A slew of new Saas tools have come to the forefront which enable us to write tests that check that everything is the same that it was (even if we moved from BEM to CSS-in-JS).

So grab that keyboard, refactor your CSS, because writing tests for it is now possible!

Building the most inaccessible site possible with a perfect Lighthouse score
Google's built-in testing tool Lighthouse judges the accessibility of our websites with a score between 0 and 100. It’s laudable to try to get a high grading, but a score of 100 doesn’t mean that the site is perfectly accessible. To prove that I carried out a little experiment.

5 Tools For Automated Accessibility Audits
Some of the quickest accessibility wins can be simple fixes, but if you don’t know what to look for, they can be hard to spot. Identifying these issues is important, which is why there is a whole slew of web accessibility checkers available to help identify these problems. I want to introduce you to a few tools that you might find helpful in identifying accessibility issues. Just remember though, that automated tests can only catch a portion of all issues.

Keeping a React Design System Consistent Using Visual Regression Testing
Ensuring visual consistency is one of the biggest challenges of working on a UI component library. Since visual regressions in one component can lead to unwanted changes across an entire application, it becomes vital that we test not only our components functionality, but also their visuals. What follows is the story of how we introduced visual regression testing into our React component library that implements our design system.

Short note on getting spaced out with SC 1.4.12 Text Spacing
One of the new success criterion in WCAG 2.1 is 1.4.12 Text Spacing. Conforming to this criteria provides accommodation for people to modify their text styles according to their needs.

The success criterion defines a set of text styles that must be supported. Thinking that this should be pretty simple to test using a bookmarklet I went searching for one that someone may have prepared previously. Not finding any, I whipped one up.
