Beginning to Demystify ARIA

If you didn’t know this already, I usually cross post all these on DEV. When I cross-posted about why accessibility isn’t an edge case, I got a comment wishing accessibility was more straightforward to implement. I didn’t find learning to make accessible solutions to be that challenging once I was up to date on HTML and CSS best practices, so I was genuinely curious about where they found it difficult. When they answered, it seemed like the primary pain point was ARIA.
I’ve seen a ton of confusion about ARIA and when it should and shouldn’t be used. What do these ARIA attributes even mean? Is there a list of all the attributes? I am thinking about making this into a series, maybe going over a few ARIA attributes a week and how they can be used, whether I like them, etc. Before I get into the weeds about all the ARIA attributes though, I really need to get a few things straight about what ARIA is used for, and what I don’t think you should use it for.

What the hell is ARIA?

ARIA is a bunch of attributes that you can add to your elements to give them extra context and meaning. This can be useful for a lot of things. Here is what I find helpful about ARIA:

Telling you when you are loading dynamic content
Alerting a user when something important pops up
Telling screen readers when the state changes
Adding some extra context if needed

The documentation on ARIA is pretty damn intimidating. Even as an accessibility person, I find it a bit daunting. The way I learned about ARIA is by opening up a well-used application like Twitter. I then inspected the elements and searched in the HTML for aria and looked at all the attributes. I then turned on my screen reader and actually listened to what was actually announced when I reached that particular element. For example, when I use VoiceOver on Mac and open up the homepage of Twitter, this is the markup of my profile picture in the upper right-hand corner:
