Why border of not showing in IE?

Question

Why border of tfoot tr:first-child not showing in IE. I\'m checking in IE7.

font-weight:bold; background:yellow is showing in IE but border

Answer 1

I would avoid styling tr elements because they don't really "exist" as such, apart from for semantic reasons. You're better off targeting the table cells themselves, with something like this:

table tfoot tr:first-child th,
table tfoot tr:first-child td {
    font-weight:bold;
    background:yellow;
    border-top:2px solid red; 
    border-bottom:2px solid red;
}

Also, since you are targeting directly nested elements, you can use the child selector, which is faster for browsers to parse (they only have to search one level up/down).

table > tfoot > tr:first-child > th,
table > tfoot > tr:first-child > td {
    ...
}
