Hello. Do not tell me how to implement this: hover effect?
This is the site header with the menu:

Snag in the torn edge of the bottom. How to do it is not a problem, for example, after: before on the background we put the picture and repeat-x.
But how to change part of this ragged edge? (Change - change the color of a specific area.)
The fact is that it is different under all menu items (it starts from different places), i.e. make one picture of a ragged edge and put it in when: hover, then there will be a discrepancy according to the drawing.
Thankful in advance for ovtet!
