BGs not clickable in Safari

[rawrzerawr]

I had to fix it for IE so that they we're able to click the BGs but someone just told me that they can't click them in Safari. How can I edit it so that the BGs are all clickable in every browser? I know I had to edit the height and width of something, but I completely forget, thanks!

Another just told be it happens to them in Google Chrome as well. Any help would be great, thanks!
