It’s good practice to write good, error-free code. And once you’re out testing your prototype with users who have access needs, you’re going to be wanting well-formed HTML with zero errors, and as few accessibility problems as possible. While these tools won’t make your prototype bulletproof, they’ll go a long way towards fixing your mistakes and guiding you in the right direction.
