so I go to my css template that I choose and did the following, for some reason it changes the color from black to blue. I did paste the #poweredby { display:none; } at the bottom of the css, dont know if that matter or not.
.comment_preview div:hover {
color: white;
background-color: #253F67;
}
#comment .josc_ads {
text-align: center;
}
#poweredby { display:none; }
