Firefox (Gran Paradiso) 3a7: -moz-initial and forms
Recently I was chatting with Rapha Martins, and he mentioned a feature he’d like to see in CSS: a ‘default’ value for properties; that is, if you change the value of a property, a keyword that would change it back to the browser default rather than you having to specify that value again.
That has been proposed for CSS 3, with the ‘initial‘ value, and it’s been introduced into the latest preview of Firefox 3 (Gran Paradiso), with the browser-specific -moz- prefix. I’ve put together a quick couple of basic examples of how it will work (you will, obviously, need the latest preview to see them).
