Simple CSS: Text won't center in a button

Question

In Firefox 'A' shows in the middle, on Chrome/IE it doesn't:

<button type="button" style="width:24px; text-align:center; vertical-align:middle">A</button> 

Note the following has the same results:

<button type="button" style="width:24px;">A</button> 

Edit: Now seems to be fixed in Chrome 5.0

Answer 1

Testing this in Chrome, you need to add

padding: 0px; 

To the CSS.
