XF 1.5 RSS icons

Can anyone help me with something I can place into extra.css to remove all rss icons from my forum but not lose the rss function ( I am auto sharing to FB and Twitter still.)


Tell me why I get a directed to a page titled:
"This XML file does not appear to have any style information associated with it. The document tree is shown below."
when I click on any of these rss icons.

Either way I'd like to remove just the icons, not the whole function.

Thanks, that was fast. I have so much custom stuff I am worried about upgrading, so should I do most things in extra.css? will that make it easier to apply most things after an upgrade.
