displaying a div only on tumblr blog homepage?

Question

I have a fairly novice understanding of CSS and HTML, and I\'m trying to do something that I think should be relatively simple (in a custom tumblr theme I\'m creating), but

Answer 1

This will work:

{block:IndexPage}
  

    This is displayed only on the index page.
  
{/block:IndexPage}
