I've found that declaring a doctype on a few of my sites actually stops some of the styles working from my main vexen.css, and although I tried for ages to get it to work for the particular doc-type (predictably I was using the least strict one), I couldn't fix it so I had to leave off the doctypes.

On some specific pages I found it didn't interfere, so I left it on, such as on my main http://www.vexen.co.uk/index.html (However I just rechecked and it's returning some odd error about not being to understand the doc type, I'll look at that later)

I'm guessing that it was sticking to a specific standard, and therefore ignoring/altering the way it read certain attributes, but I wasn't having any luck getting those attribs to look good just sticking to the standard, so I had to remove the doctype commands with plan to try again another day!
