it is so much like html I just went to
www.w3schools.com and picked up on the few changes. All my pages are now coded in XHTML Strict. I had one problem when making this switch, the link target attribute wasn't valid. So I got a simple javascript file and used the rel attribute.. I works fine for people that have up-to-date browsers and the few that dont, well links opening up in the current window, isn't going to kill that much traffic.. but yeah, if you want to see my current site coded in xhtml,

and yes.. I suppose html loose is replaced by xhtml transitional... I call them the I don't want to go all the way and bring my site to the top lazy way out of it DTD.. but whatever..
