I have found one meta tag for fixing the issue in IE 8,7,6 browsers and other browsers
This tag displays the site as same as in IE7,IE6&IE 8.
I tried this code in my project the site was working fine as same as in IE 7 browsers.
This tag needs to be first in the <head> (before any css):</head>
<meta http-equiv="X-UA-Compatible" content="IE=7" />
This is a small trick for browser compatibility :-) Please try this one.
