I want to add Google AdWords to my site but the script I\'m supposed to add creates an iframe in the dom. This iframe is visible and moves down 13px (its height) all my page.
you can also set max-height: 0; instead of display:none; Not sure of implications of display none on the iframe. This works back to ie6.
iframe[name="google_conversion_frame"] { display: block; max-height: 0; }
