Try adding a bottom margin. and adjusting it to suit:
PHP Code:
margin-right:150px;
margin-top:50px;
PHP Code:
margin-bottom: 10px;
Or to cut down on the CSS delete all margin settings in the #banner_ad_top and enter the following:
PHP Code:
margin: 50px 150px 10px auto;
It does the same, and the values are in order of top, right, bottom and left, in a single line.
Since 4.0.2 has been delayed further, I will setup a new test board and apply an IE fix. Personally, I hate IE - but we still have to cater for it's users.
I do not have a test board setup to try this on, but IE uses non-compliant CSS therefore it is easy to break. Perhaps, when they start losing more users of their browser they will change their ways. ...well, we can dream!!
