Greg Rickaby covers four basic principles to simplify designing for accessibility, which can seem overwhelming at times: (1) If you write semantic HTML, browsers will do a lot of the heavy lifting; (2) Use the “label” tag a lot; (3) Don’t rely on visual cues; (4) Make everything usable on a keyboard, mouse, and touchscreen.

Taylor acknowledges that accessibility implementation probably won’t be fast or easy: “Donβt feel pressured to meet every requirement on the first pass through your site.” Sound advice there.
