HTML5
Getting started with HTML5 is very easy.
HTML 5 is compatible with the XHTML syntax of self-closing tags, so, if you already use HTML5 then making the switch will be easy. Other XHTML features inherited by HTML5 include lowercase tags and double quoted attributes (eg, title=”the title”)
The Doctype declaration in HTML5 is so much easier to remember when compared to XHTML:
<!DOCTYPE html>
There’s a lot more to HTML5 and I will update this entry as I get more info.
