How to style block on certain pages? I would like to add a  around a menu block I am displaying on a section of my site to style it differently on a certain page only. 

How do I do this? Can I target a certain page with a conditional somehow?
If your theme utilizes body classes and you don't need to modify the HTML structure you can simply do:

body.page-node-1 #block-block-1 {
  /* styles goes here */
}


Replace "1" above with the ID's for the node and the block.
