I like these buttons but i need them to only affect buttons with a unique id (or class). how to change them over? I attempted to do this but it did not work should they be btns in divs with the css on the div or should the button have an id or what?

```
<pre><code>
<html>
<head>
<style type="text/css">

input[type="submit"], input[type="button"] {
  -moz-border-radius: 10px;
  -webkit-border-radius: 10px;  
  border-radius: 10px;
}

input[type="submit"], input[type="button"] {

float: right;
  margin: 2em 1em 0 1em;
  width: 10em;
  padding: .5em;
