The other day I was looking at my rss feed on my mobile telephone and it looked great. The only problem is when I click on one of the links it takes me to a page which was not designed for a small mobile telephone.

Is there any tag I can add to a page that tells a mobile telephone to display only <mobile content start here> THIS <mobile content end here> and not everything else on the page like ads etc.?

If not what do I have to do to be mobile compatible?
