Prevent clicking button creating pressed effect - html

Question

I have a button on a form;
<button type="button" class="button" onclick="validate_form_newsletter_wide( form )"><img src="index_htm_files/btn_newsletter_wide.png" alt="Send"></button>
It styled using;
<style>
button::-moz-focus-inner,
input[type="button"]::-moz-focus-inner,
input[type="submit"]::-moz-focus-inner,
input[type="reset"]::-moz-focus-inner {
padding: 0 !important;
border: 0 none !important;
}
#form_newsletter_wide .button {
position:relative;
float: right;
cursor:pointer;
border: 0px;
padding: 0px;
margin: 0px;
margin-top: -1px;
z-index:100;
}
</style>
When clicked in Firefox nothing about the button changes, in Chrome I get a highlight border around the button which I can live with but in IE it's more of a pressed effect where the button almost seems to move down and right. Is there anyway to prevent this?

Answer 1

It's a browser behaviour, a simple solution is to use a link tag instead of button (since you're calling a javascript function).
<img src="myimg"/>
If you still want to use the , I've found that there are some characteristics on each browser (in a simple debug):
Chrome adds outline and padding
Firefox adds a whole lot of stuff with the standart button border
IE messes with the inner text position
So to fix them, you have to manipulate the pseudo selectors for the button behaviour. And for IE, a good solution is to envolve your text on a element, and make it relative positioned. Like so:
<button type="button" class="button"><span>Buttom or Image</span></button>
<style>
button,
button:focus,
button:active{
border:1px solid black;
background:none;
outline:none;
padding:0;
}
button span{
position: relative;
}
</style>
