cross-browser height for tabs navigation

SOFTWARE: css

give ul or div height as PERCENTAGE

IE7 was getting different height of navigation tabs (unordered list set to diplay inline) than Firefox, Safari etc. To fix, I gave the ul a height in percentage instead of px or ems. The value of the percentage in my case doesn't matter. For example, I can change it to 10%, 5% etc. with no visual difference. But, it makes everything display the same in all browsers I tested.

globalnav {height:5%;}

Cool stuff.

Internet Explorer conditional styles

SOFTWARE: css

To call a different stylesheet that includes special css fixes for IE versions less than IE7, add this in your head section while calling stylesheets:

<!--[if lt IE 7]>
<link rel="stylesheet" type="text/css" href="/css/ie6.css">
<![endif]-->

You can do other nifty things with this logic, like calling a special javascript file. Since only IE sees the conditional anyway, other browsers will skip it.
