The World Wide Web consortium provides a free HTML validator to check your website for compliance. This is a great tool not only to ensure compliance, but also to find problems with your code that don't produce errors.
Yes alan, I agree and I do it for my PositionMap skin, which w3c valid too.
So it's useful to allow to add this kind of custom code in order to make the skin more flexible but it can break its w3c validness.
I know, but at least they can start out compliant.
I posted this because I ran it on my website and found some major things missing from slide.htt, although most of the errors in my index pages were from text files I include, not the index.htt itself which only had minor issues.
If you are into any web development and or compliance issues, I'd highly recommend the FireFox extension, Web Developer toolbar by Chris Pederick. It's an easy install (and easy uninstall if it's not to your liking) for anyone using FireFox. And if you're not yet also using FFx, well the boat left the dock 20 minutes ago
Get it at either (and check it's "tools" tab for various validations):
Yes, this is important. I found that the "Experience" skin displays
correctly in IE but fails in Mozilla (errors in link highlighting colors).
I didn't test it in FireFox. All browsers should be checked before
posting a new skin.
