Buttons & CSS

Hi,

I have a Mac Mini running MacOSX 10.4.7 which I use primarily for
cross-platform website testing.

There seems to be an inconsistency with the Safari and Camino browsers in
the way the handle (or, rather, don't handle) styles in cascading style
sheets for <input type="button"> tags.

Example

I have the following style set up in a cascading style sheet:

..focusButton
{
background-color:#addfff;
}

And in a standard webpage, I have the following HTML:

<input type="button" id="cmdLogin" value="Log in" class="focusButton"
onclick="siteLogin();" />

You can view this live here: http://www.sanctuaryrig.co.uk (click the logo
to enter the site, the button in question is in the top right-hand corner)

This works perfectly in FireFox, Netscape, Opera, Mozilla and SeaMonkey, all
of which show the button with the light-blue background colour.

However, in Safari and Camino, the button's background is not modified. Is
this a known issue specifically with those two browsers?

Any assistance gratefully received.

Mark
