I'm new to CSS and am using the Yahoo YUI libraries in a project. I am learning as fast as possible, but apologize in advance if this is too rookie of a question. Can anyone help me understand the following CSS that I came across in the layout manager CSS:

I have been unable to figure out what the * (star) does to the rules (styles) in the following CSS???

.yui-skin-sam .yui-layout .yui-layout-unit div.yui-layout-bd { border:1px solid #808080; border-bottom:none; border-top:none; *border-bottom-width:0; *border-top-width:0; background-color:#f2f2f2; text-align:left; }

Thanks in advance, Bill
