How can I change the CSS of all div classes (i.e. <div class="boxBottom">) and the background of the gallery pages from grey #333333? to #000000 with a simple emboss effect, to eliminate the grey of the entire site?

Add this to your CSS:

.boxTop,
.boxBottom, 
#photos { 
    background: #000 !important; 
}

If there are still places with the gray background, post the links here and someone will help you to add to this CSS.

Thanks Denise. I would like to change the loading thumbnails and the pop-up contact form as well.

I have no idea what you mean by "loading thumbnails".

I don't see the CSS I posted above on your page. Please add the CSS, then post back with a link to any pages that still need to be changed and an explanation of what you want to change.

Blank grey thumbnails until the images load:

Contact form:

... And how can I add some padding to the top of the gallery box?

This didn't work:
#galleriesBox {padding-top: 3px;
}

I don't see the black / gray thumbnails.

This will change the background of the contact panel to black:

#contactUsPanelmyContactPanel0 { background: #000; }

These are the placeholders until the photos are loaded.
