If you’re a Web developer, you’ve probably read various methods for filling the need for a scriptable CSS style sheet. Most are a variation on a theme, here I present my preferred method, that is unlike others I’ve read (and it does some pretty cool stuff too). I’ve been using the core of my scriptable CSS system for six months now, and I have found it invaluable to the way I work.

The core need of a CSS scripting system is the need for a color substitution system that would streamline color selection for the web sites I’m working on. Most of the other scriptable CSS systems do exactly that, so we’re not breaking new ground here.

Lately I’ve been working for a unique client that understands the importance of accessibility, but they view it as a black and white issue. It’s not entirely their fault, but that’s a rant for another day. The core problem is that they equate accessibility to making a site usable by people using a screen reader. If only real accessibility were that easy.

Making a web site accessible for those who can’t see pixels on the screen is important, but for every blind person using a computer, there are (probably) dozens more that we also need to think about, the gray area. These are the people who may have difficulty reading the average well-designed web site. Accessibility for these people is as important as accessibility for the sightless.
