Hover menu

I use the “wp_get_pages” tag in my sidebar, and my navigation menu is a “block-like” menu with links as text inside these blocks.

How can I get the list element (the “block”) and the link itself (the text and its background) to hover simultaneousely? When I place the cursor over the list element, this “block” changes background colour, while a small area (a small square) around the text keeps the old colour.

This also works vice versa, when I put my cursor over the link, the background of the text changes colour, while the rest of the block (the list element itself) keeps the old colour..

Please help me, this is so frustrating.. =)
