:hover not working on gallery

[ainarade]

Hello to everyone! i hope someone can help me with the problem I have. I've been looking for answers all over the forum, but didn't find an answer that would solve my problem. The fact is that the hover effect is not working in all my coppermine gallery.

This is my gallery: http://myfansiteonline.com/portfolio
And this the code I want to work, but because of some reason, it's not working, as you can check:

Code Select Expand


.catrow_noalb {
background: #3F2940;
color: #604663;
padding-top: 6px;
padding-right: 10px;
padding-bottom: 6px;
padding-left: 10px;
}

.catrow_noalb:hover {
background: #513552;
padding-top: 6px;
padding-right: 10px;
padding-bottom: 6px;
padding-left: 10px;
}

.catrow {
background: #3F2940;
padding-top: 6px;
padding-right: 10px;
padding-bottom: 6px;
padding-left: 10px;
}

.catrow:hover {
background: #513552;
padding-top: 6px;
padding-right: 10px;
padding-bottom: 6px;
padding-left: 10px;
}
.thumbnails {
background-image: url("thumgaga.png");
padding: 5px;
}

.thumbnails:hover {
background-image: url("thumgaga2.png");
padding: 5px;
}
