CSS Validator color warnings are not errors

A highly accessible web site uses web standards, which means XHTML and CSS. When using the W3C CSS validator to validate your CSS, many times the following warnings come up: “You have no color with your background-color” and “You have no background-color with your color”. In his blog posting, Roger Johansson explains why CSS Validator colour warnings are not errors. He states:

Those particular warnings are there for accessibility reasons and to remind you that you need to take care when specifying colours. The validator is trying to help you reduce the risk of your author stylesheets interfering with user stylesheets or system-wide colour settings.

One Year Anniversary

So it’s been over 1 year since my first Web Axe podcast (Sept 18, 2005). My long-time friend Mike (see Most People Are DJs) got me into podcasting. He and I started the e-zine O.D. Mag a decade ago. Then last year, Mike got me into the Detroit Podcasters Network, a great group of computer nerds who do great podcasts, and meet every month and drink beer.

So I said to myself, what do I enjoy, that I know a lot about, that would be unique. Web accessibility of course! I have been programming web sites for accessibility (and standards and usability) for over five years now, and for some reason just find it very fun and interesting.

I’m making more and more connections, and learning more and more about the whole web development industry. It’s remarkable how much more there is to learn every year. Thanks to Ross Johnson of 3point7designs.com, who’s joined in the Web Axe podcast venture. It’s a lot of work, and a lot of fun, and I’m expecting bigger and better podcasts in the future!
