How to place button above the line in IE7? Please don't change the HTML structure. Thanks.

do the simple hack , change the order. write <button> before the text and also write float:left on h2

<h2>
 <button>Action button</button>
 This is heading 2   
</h2>

DEMO

Note: also can work only writing float:left on h2 but then complete div slip below

From what I can tell, you'll have to change the structure by putting the the button element to before the "this is heading 2" text. (EDIT: diEcho beat me to it).
Otherwise you'll have to use position:absolute which can cause other problems. Using position:relative on the h2 may help.
