So you’ve read Eric Karkovack’s post on WordPress accessibility, and now you want to make future sites you work on accessible. Great!

Building websites that are accessible to all users has become a major focus of our industry. Not only do we need to ensure that our creations look great on different browsers and devices, but they also need to work well with assistive technologies like screen readers.

About a month ago, I read a headline in the Post Status newsletter called “Let’s No-Code This Thing and All Go Home.” It linked to an article that stated:

This Quick Guide walks you through searching through all the files in a WordPress plugin using the Sublime Text code editor. This process works not only for searching through WordPress plugin folders, but for searching the contents of any folder using Sublime Text.

CSS Grid is a very cool technology, and one I think more and more WordPress developers should both know about and use. While I’m hardly a CSS expert, that’s specifically why I feel well-qualified to tell you to learn CSS grid: if this non-expert can find it great and useful, surely it has arrived as a technology you must know.

WordPress development is a hugely useful skill, but it’s also tricky to learn—especially if you learn things out-of-order and try to tackle advanced topics while remaining confused on the fundamentals.

I recently needed to modify a JavaScript file in a WordPress parent theme. The script was doing almost what I wanted, but not quite, so I wanted to make minor changes. In your case, you might want to entirely override a parent theme JavaScript file in your child theme, or even deactivate a parent theme JavaScript file altogether.

When I learned math, I didn’t really understand the modulus function. In fact, it was until I learned PHP that I understood the value of a remainder from division. PHP’s role in making websites makes the modulus operator (or modulo) much more important than it ever was in math class for me.

This video and text Quick Guide explains how to prevent browser caching of CSS files in WordPress. The CSS cache busting tricks here will work outside WordPress, too: you’ll just need your own method of adding query strings.

There’s a tricky thing about this idea, “WordPress add header script” I have written down as our topic today. That problem is that “adding a header script” can mean a bunch of things. In our case, I’ll be explaining how a WordPress user (who may be a developer, but doesn’t necessarily understand code that thoroughly) can add a JavaScript file or code to their pages.
