Change style.css for 1 page

Hi,

I am wishing to change the style.css for one specific page.

In my style sheet I have a border round the “featured” within content on pinksimpletheme.

I have one specific page where I have removed the sidebar but also need to remove the border for the content.

The code on the style.css for the border is:

#featured {
		border: 1px solid #DDDDDD;
		padding: 10px;
		margin-bottom: 10px;
		height: 245px;
                      z-index: 300 !important;
