Running our MOSS sites in IE-7 compat with IE-8

We had worked on some MOSS portal sites and wanted to make sure the rendering is fine in IE-8 also without making any changes to the CSS, so the best thing we did was we added the following tag to our Master Page just below the HEAD html tag and then it rendered all our pages in IE-7 mode even while browsing from IE-8:

<!-- Use IE7 mode in IE8 browser -->

 <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

<!—End of Use IE7 mode in IE8 browser -->
