We cleaned up a few small errors on the site to once again ensure we are 100% XHTML 1.0 Strict compliant. We try to ensure all of our releases meet the high standards of valid coding. There are times when we do stray and have an error showing here or there. I personally feel that using sites like W3C to check for valid code is more of a guideline than code law. Usually we can work around a error when needed. There are a few inherent pitfalls when designing websites. One is accounting for screen resolutions. Many users are still using 800×600 screen resolution which can create problems for designers. Now that broadband is much more widespread and lcd widescreen monitors are getting less costly, designers are putting more and more on a site. More information as well as graphics. Then you have to deal with the differences in the major browsers. What works in one may not always work in another. You constantly have to check a site in different browser situations. Sticking to valid code standards lessens the likelihood that you will have to redo coding for different browsers, but as with anything there are many exceptions to the rule.
