Class is only becoming more important. Focusing on its original definition as an attribute for grouping (or classifying) as well as linking HTML to CSS, recent front-end development practices are emphasizing class as a vessel for structured, modularized style packages. These patterns reduce the need for repetitive declarations that can seriously bloat file sizes, and instil human-readable understanding of how the interface, layout, and aesthetics are constructed.

My biggest overall takeaway from this experience was how inaccessible many sites are, and how frustrating it must be to a person with certain disabilities to regularly have poor web experiences. As developers, it’s our job to keep this in mind when creating any site, whether it “needs to be accessible” or not. You can bet that these lessons are being baked back into our work. Hopefully some of these will make it into your next projects as well.

The reality is that accessibility is simply a key part of UX. A truly outstanding digital experience is a fusion of accessibility, usability, creativity and technology. The trick is to weave those things together, and to do that successfully there needs to be a cross pollination of skills and expertise.

The good news is that accessibility is usability under a magnifying glass. If you’re thinking about great usability, the chances are that you’re already thinking about great accessibility too.

This one is for testers who use NVDA, a free screenreader, to test online content for any access issues.

What does the outline property do?

Why I created this resource

This list should not be taken as a stab against tools and tool vendors. I’ve said numerous times that we should do automatic testing first. When done properly, automatic testing offers a degree of efficiency that cannot be matched by other methods. However, that doesn’t mean that we should leave our compliance up to automated testing. As the tables above show, there are 9 WCAG Success Criterion (in Level A and AA) that cannot be tested for in any meaningful manner using a tool. There are another 13 that can be tested for automatically but require a human to verify. Full compliance and risk mitigation always requires the involvement of a skilled professional reviewer, even when you have a tool as well.

I first got to know Kim Patch when we worked together on the W3C User Agent Accessibility Working Group. As a resident of the Web since it’s inception and a long term voice input / non mouse user I was always fascinated to hear what she had to say about making web content, and how a browser interprets that content, accessible.

This mantra is as true for the mobile Web as it is for the desktop Web.
