My theme has these definations:

/*forms elements*/
input.formButton {border: 1px solid #5E5D63; color: #000000; font-family: verdana, tahoma, arial, helvetica, sans-serif; font-size: 9px; text-align:center; background: url('inputbg.gif'); }

textarea.formBox {border: #000000 1px solid; background: #ffffff; font: 11px verdana, arial, helvetica, sans-serif; }

input.formTextBox {border: #000000 1px solid;background: #ffffff; font: 11px verdana, arial, helvetica, sans-serif; }

select {border: #000000 1px solid;background: #ffffff; font: 10px verdana, arial, helvetica,sans-serif; }

Some Form Buttons are affected, some are not.
Like "Send" button of INBOX is affected, but "SEARCH" of NewBB isn't.
I want all the Form buttons to be affected by the definition.
How can I do that?

you forgot about Submit and Reset classes

I am not good at CSS. Can you show me sample definitions for Submit and Reset classes?

If you agree to forget about IE - I can't write it in "IE-compatible mode"
