- 4 versions in 7 years - 6 versions in 6 years

Netscape lost that war...

1

Dropped HTML4 stuff

<dir>
↓
<ul>

1

HTML5 should be
similiar to HTML4 and
XHTML 1.0

HTML5 should
explicitly require CSS.

1

Dropped HTML4 stuff

Presentational elements
and attributes removed.

1

„name“ dropped, use „id“

1

Problematic Attributes

1


<html>

The version number. :-)

1

Updated elements

<meta <meta http-

Better consistency

<a href=“http://
m.twitter.com“
rel=“alternate“
media=“handheld“>
Twitter Mobile</a>

Better consistency

style, tabindex, title
Now for all elements!
