Think you know how to create null alt text, add labels using ARIA, or craft good link text? Unfortunately, some of these accessibility features are still not properly used. This presentation will review common accessibility and usability errors surrounding alt text, form labels, link text, structure, and more.


When I first started in the accessibility field I quickly tired of presentations that reminded me to use alt text, add labels to form fields, and to use semantic HTML. Since they are so basic, I vowed that I would not repeat these topics in my presentations on accessibility. I now realize that while they are obvious to me as someone in the accessibility field, these techniques still need repeating and clarification.

This presentation will review common accessibility errors surrounding alt text, form labels, link text, structure, and more which are still common on websites. Come learn ways to properly add null or empty alt text. See how you can use ARIA to enhance your link text and why you probably shouldn't. We will look at real-world examples of common errors and review the proper implementations.
