Applying a style sheet class to a Form

[eluser]MightyBishop[/eluser]
Hi all,

Still very new to all this, but loving it! Bit confused about applying style sheets to the form_open() command.

Say I want to end up with something like this in my page:

Code:

<form class="form-style">

How do I go about applying that class to the form_open() command?

I read somewhere else about adding on a style as an extra parameter to something, but for the life of me I can't remember - old age creeping in!

Thanks for any help,

Best regards

JB
