Help with styling thumbnails within WordPress pages.

Hi guys,

I’m trying to apply a specific style to thumbnails within a page titled ‘Gallery’ on my blog.

Here’s the style i’m trying to apply:

#thumbnail{
	display:block;
	float:left;
	width: 100px;
	height: 50px;
	overflow:hidden;
	margin:4;
	background-color: #ffffff;
	border-bottom: 13px solid #111111;
	border-left: 5px solid #111111;
	border-top: 5px solid #111111;
	border-right: 5px solid #111111;
}

I thought I could accomplish this easily by putting each thumbnail in a div but I learned that WordPress won’t allot divs within post pages. There’s probably a very easy way to accomplish this, but I’m a real newbie when it comes to CSS.

Thanks in advance…
