Front size problems how to fix?

Hello, all these templates that comes with cs-cart has the same problems by opening in Safari on iPad and iPhone (Safari on PC has no this issue)

The problem is: the central column size font is about 40% higher that other columns. quick links (why?) is also font higher than normal to the about same value. I tired today to find out where the problem, playing several hours with styles.base.css and styles.css but no result.

FF and IE has no this kinds of issue all template has the same font size.

According to first line of css all fonts should be (normal 13px Tahoma, Arial, Helvetica, sans-serif;), could someone help us to figure out where this problem comes from?
