I usually shy away from About.com, but I recently came across a piece worth mentioning. In the article Are Your Web Pages Color Sensitive? from the HTML/Web Design section, Jennifer Kyrnin provides some good information and techniques for web development with color blindness in mind. Here are some good tips from Jennifer:
- Don’t use only color to indicate something specific on your page.
- Desaturate your images to see if they still have impact.
- Avoid placing red and green together.
- If you can, find a color blind friend or relative to look at your site.
Did you know that color blindness is an issue with 8 to 12% of males of European origin?
In his blog Yes, we need accessibility laws, Eric Eggert gives an argument for why we need better laws for web accessibility. He states that a good accessibility law should do:
- Create awareness.
- Do not create a climate of fear.
- Create mediations.
- Reference international standard.
- Be inclusive.
In the article Lightboxes and keyboard accessibility from 456 Berea Street, Roger Johansson describes how a lightbox should function with a keyboard. He states:
- Let me use the left and right arrow keys to step through images in a slideshow.
- When I press Esc, close the lightbox.
- Do one of the following:
- Either add focusable elements (links or buttons) for close/next/previous, put keyboard focus on the first focusable object in the lightbox, make sure I can’t tab to something behind the lightbox, and make it visually obvious which object has keyboard focus.
- or close the lightbox when I press Tab.
- When the lightbox closes, return keyboard focus to where it was when I opened it.
In addition, Roger cites the following two articles:
- Building a Better Lightbox by Josh Habdas.
- The Trouble with Lightbox (and its Variants) by Jonathon Christopher.
