id you see that button at the bottom of this page? That’s a W3C XHTML valid button. You can click on it to validate my site. The first time I validated my blog I got around 40 errors. After two hours of fixing errors I got my blog error free. But why would I want to have my blog XHTML valid? My blog worked without validation too, right?

Having a website with XHTML errors will also make the pages load slower, depending on the amount of errors. The webrowser has to fix the errors before loading the page. That’s why you can’t really see the errors (except with a validator or by looking at the source code).

There exist various webbrowsers, and they all fix these errors differently. So in some cases your webpage will look different in FireFox than in Internet Explorer for example. You’ll probably want all your users to see the same page.

I think validating your site is worth the effort. What about you?
