HA. So true.
Accessibility is one of those grey lines where yes things should be usable, but there is a certain understanding that it should be without the sacrifice of creativity. A lot of accessibility is related to code, though. For example, a user needs to be able to tab through menu items with just their keyboard. For those who are blind, other things like using the right heading tags so someone can “listen” to the headings and decide if they want to hear the body text. On you part as the designer, you could say your design should be organized well into heading categories, and that your navigation isn’t so wild that a user would have difficulties tabbing through.
This is a good suggestion, maybe I’ll write an in-depth article about accessibility next.
