I’ve not actually checked to see if my site is currently compliant with any XHTML or CSS standard, I would imagine if they are not it is redundant ‘covering’ code anyway… that aside I do try and keep up with the goings-on in the CSS design ‘area’, and A List Apart is a great place to start.
It was with some intrigue that I spotted the article “Retooling Slashdot with Web Standards”, which includes the line “underneath the hood you will find an old jalopy” (OK, deliberately taken out of context). What follows is an interesting look at converting a site to CSS based design AND achieving compliance. Interesting stuff.
