Float:right; bug in IE7 causes ad to move down, how to fix it?

I am using two ads (160x600) in the right sidebar of my blog. For the ad that is on 开发者_如何转开发right side I am using float:right property. Both ads appear side by side in all browsers except in IE 7 where the righ-sided ad floats down.

I will be thankful if you could provide me some good suggestions.

If you switch from a float: auto; or a float: left; to a float: right; in IE7 it creates a <br clear="all" /> effect. The floats need to match. In this case, I'd say you need to make both of the bottom ads float: right; and reverse their order. This should work in all browsers.

IE7 does not support in float:right; and clear:both; elements. so you have to use only float:right; and width:100%; it has get the full width automatic comes down after give the text-align:right;
