Well this class is giving me a lot of problems, can somebody help me out?

We skipped that class. But maybe if you have a concrete question...?

Ok here it goes lol

-->when a mouse pointer hovers over a link, change the background to yellowand the font color to black.
--> Display each li element whiting the #hole_list selector as an inline element with a margin of 0px, a padding space of 0px above and below the element, and padding space of 5px to the left and right.

I am worry for this class, cuz the books is not good at the explanations =(

I meant if there is something you don't understand. I'm not going to to your homework for you.

The second quostion more or less spells the it out for you. You are looking for the following CSS properties: display, margin and padding. For the first assignment you want :hover.
