I recently started to teach myself web development from scratch and am having trouble.
I created a fixed div for the header of my website using a basic html 5 code. The header works great for the most part when scrolling over content, but once it reached a Google ad placement the ad seems to overlap it and scrolls in front the header instead of behind it. Any suggestions on how to fix this problem?
It would help to see some example code, but to begin with try setting the z-index using CSS on the header so that it is higher than the google ad div.
