css - input type=submit text vertical alignment in Firefox

Question

I'm trying to style my form buttons and I'm experiencing a problem in Firefox that I can't get to the bottom of...

I want to style certain <a />s and <input type="submit" />s to look the same (I have a button background image, using a sliding-doors technique to apply a hover effect.)

This all works great, except in Firefox, the input submit text is slightly lower down than it should be. IE and Safari/Chrome work fine.

Anyone got any ideas?

Thanks

<div class="buttons">
    <a href="#" class="button btn-small-grey">&laquo Back</a>
    <input type="submit" class="button btn-large-green" value="Save changes" />
</div>

.button
{
    cursor: pointer;
    border: 0;
    background-color: #fff;
    color: #fff;
    font-size: 1.4em;
    font-weight: bold;
    outline: 0;
    font-family: Arial, Verdana, Sans-Serif;
}

a.button
{
    display: block;
    float: left;
    text-align: center;
    text-decoration: none;
    padding: 5px 0 0 0;
    height: 22px;
    margin-right: 1em;
}

.btn-small-grey

    width: 96px;
    background-position: 0 -81px;
    background-image: url(/assets/images/buttons/buttons-small.gif);
}

.btn-large-green

Answer 1

I found this post because I had resolved this problem a few months ago and when I ran into it again today, I couldn't remember what I'd done. Nice. After poring over my css I finally located the "fix". I can't take credit because I found it on the web somewhere, but hopefully it will be as useful to you as it has been for me:

input::-moz-focus-inner /*Remove button padding in FF*/
{ 
    border: 0;
    padding: 0;
}

I hope this helps.
