It seems that the filter: opacity property is not functioning as expected in IE8. Despite having used it successfully before, I am currently facing issues with its implementation. Strangely enough, Firebug does not display the filter rule at all; only normal opacity is shown.
Does anyone have any insights or suggestions on how to resolve this?
ul.products-grid img:hover {
opacity: .8;
filter:alpha(opacity=80);
}
