The case for semantic HTML
It is easy to create HTML that works, but current best practice suggests that creating valid and Semantic HTML is an important goal for various reasons including usability and accessibility.
Unfortunately, while validation is a relatively easy task to understand and achieve, creating Semantically correct HTML is a lot more subjective and open to debate.
Examples for semantic HTML
Instead of writing something like
<a href="#" name="d16">
<img id="vh_div16indicator" src="pix/closed.gif" alt="Closed folder">
Security
</a>
you better write this (with some accompanying CSS):
<a href="#">Security</a>
(Examples taken from Moodle's Site Administration block.)
For more examples how to make Moodle HTML more semantic you might have a look at this work in progress: Frank Ralf/Semantic HTML1.
