I am trying to change the color of the comment box of the Blogs MU theme to black. I know the following css code is where to make the change.
background: none repeat scroll 0 0 #19252F;
border: 1px solid #17222B;
margin: 0 0 20px;
The question is which file on the child theme am I suppose to put this in? And how should it be entered?
Also, where would I go to change the text color? And which child theme should it be entered in?
