Otto42, I wish that was 100% the truth. There are plenty of places that still use IE6, simply because they refuse to upgrade 100 PC's ghost images, or because they're in another country besides America.
I do a lot of multilingual sites and you'd be surprised how often the IE6 discussion comes up. Russia, Mexico, Panama, Brazil... Lots of people still use whatever came with their computer 6 years ago.
brooklynmodern, now you know why web developers/designers get paid the big bucks. :) When you need to speak a minimum of 5 languages (php, css, js, xhtml, xml) and make them work in at least 5 different alternate realities (firefox, safari, opera, IE6, IE7+) you end up doing quite a bit more work than DreamWeaver can do on its own.
My suggestion is to find a WordPress theme/template to learn off of. Use it as your benchmark and start creating your own custom themes from it. There's quite a few skeleton themes out there that have really good HTML markup that are just begging for CSS to fill in the blanks.
