Dynamically changing height of div element based on content

Question

I\'m working on a Facebook-like toolbar for my website.

There\'s a part of the toolbar where a user can click to see which favorite members of theirs are online.

Answer 1

You should take out the CSS height:25px property in the toolbar, the contents will expand the container. Also, ID selector tags are unique and you can specify directly to them without having to reference the ancestor:

INCORRECT:

 #toolbar #popUpAction  { /*some css */ }

 #toolbar #popUpAction a  { /*some css */ }

CORRECT:

 #popUpAction  { /*some css */ }

 #popUpAction a  { /*some css */ }
