Div style loop

I have an image I need to change inside a div according to each page. I have the following code but no images are showing up:

<div class="quicklink" title="read more..." style=
			<?php
			if(is_page('About')) { echo 'class="aboutquicklinksclass"'; }
			elseif(is_page('News')) { echo 'class="newsquicklinksclass"'; }
			// continue with elseif lines //
			else { echo 'class="normalquicklinksclass"'; }
			?>>

And the following CSS code:

.newsquicklinksclass { background: url (image.jpg) bottom left no-repeat; }
	.aboutquicklinksclass { background: url (image.jpg) bottom left no-repeat; }
	.normalquicklinksclass  { background: url (image.jpg) bottom left no-repeat; }

Any ideas what’s going on? Thanks.
