[quote="AutisticCuckoo"]An <input> button's text is specified in its value attribute, which means [color=red]it can only be a simple text string.[/color] If that's all you need, using an <input> is the way to go.

[color=red]A <button> can have much richer content, even block-level elements[/color]. If you need a complex button you should use a <button>, [color=red]but it does have some issues in some browsers.[/color][/quote]

[quote]In a nutshell, the button element is cool because button type=submit works exactly like input type=submit, [color=red]except that it has an open and close tag and you can put any inline element inside it.[/color] So you can put an image, or some text, or even a Flash movie were you so inclined, and style it however you like without all the odd behaviour that you get with input type=submit or input type=image.[/quote]
[quote]So, next time you build a form, try throwing in a button instead of an input type=submit. [color=red]But be a little careful, because they are not completely without idiosyncracies.
