Button Functionality
I used the button tag instead of the button type input element because it is handled a bit more consistently across the different browsers. (If you're looking for a truely consistant button look, you'll probably have better luck by replacing the button with an image that looks like a button.)
Buttons, in Perfect Layout, are designed to work hand-in-hand with the "moveOver" class. See this example:
This is because I've designed Perfect Layout buttons to be lined up with the input areas. For example:
Relevant HTML
<div class="moveOver"> <button type="submit">Button</button> </div>
Relevant CSS
button
{
margin-bottom:1em;
padding:0.3em 0.8em;
}
