Javascript including issue.

Although I did this profession for years, I wrote quite bad codes today.

<script language="javascript" src="jquery-1.2.6.js" type="text/javascript"></script>

not:

<script language="javascript" src="jquery-1.2.6.js" type="text/javascript"/>

otherwise there are lots of boring errors, such browser cannot find your javascript functions(xxx is not defined).

html height problem in ie7

css:
html{height:90%;}

this will limit page's height to screen height in ie7(internet explorer 7), instead of expected expanding page height to screen height..
