What exactly does this CSS selector with a comma match?

Question

I have a question about CSS selectors.

In my CSS file I have the following code:

.table_legenda th, td {
    text-align: left;
    vertical-align: top;
          


        

Answer 1

The , means selecting another attribute so what you should do is:

.table_legenda th,.table_legenda td {
text-align: left;
vertical-align: top;
font-weight: bold;
color: #76818a;
border-bottom: 1px solid #76818a;
border-left: 1px solid #76818a;
white-space: nowrap;
overflow: hidden;
}
