That should work fine in IE8.

A stab in the dark:

Make sure you have a doctype as the very first line of your HTML that triggers Standards Mode, such as:

<!DOCTYPE html>

In Quirks Mode, IE emulates version 5.5, which does not support :hover on elements other than a.


IE8 is not the usual culprit for :hover problems. If you can't get it to work, there's always jQuery!

$("#tabb tbody tr").hover(
    function() {
        $("this").children("td").css( { 'background-color': '#d0e4f2', 'color': '#006' } );
    },
    function() {
        $("this").children("td").css( { ... } );
    }
);
