I am new to adsense. I was wondering if I should specify the size of each ad in css (via the div I have around each ad). Or is this unnecessary? (I am not asking if I can change the designated size of the ads in css, but just if I should put in the width and height of the standard ad sizes I have chosen). Any insight would be greatly appreciated. Thanks.
You are not allowed to edit adsense code. Still the position and back ground can be changed using css...
