Trenton Moss writes a very brief but useful article at A List Apart: What Is Web Accessibility?
I think about Web Accessibility a lot. It’s on my mind when I walk the dog, as I watch TV and of course whenever I work on a web page. There’s something I want to say about it, but my brain hasn’t yet quite put it together. Anyway, this final paragraph from Trenton’s article is particularly worth mention.
Any web developer with basic HTML and CSS design knowledge, and a bit of time on their hands, can easily learn and implement web accessibility — it’s not brain science after all. Web accessibility is all about following design standards and then adding in a few simple accessibility features. It’s not just about disabled users being able to access your website — it’s about everyone being able to access your website.
