Re: XHTML of HTML5

[sliver37]

There isn’t really any reason not to use HTML5 these days.

Start off slowly, getting into the new elements as you feel comfortable. Make sure you normalise the new elements and include the html5 shiv for IE support. (if you’re not sure on these, google is your friend).

As @karlpcrowley mentioned, you can simply use the HTML5 doctype and code the same exact way you would have in XHTML.
