CSS Style for BORDER_PANEL

Classic Servoy
1

Hi,
I am just getting into using CSS style sheets to do styling for my Servoy (6) solutions [I know, very behind the times…] & I am also NOT an expert on HTML/CSS etc.
Can someone please tell me how I can change the ‘DEFAULT’ background colour for the BORDER_PANEL using a style sheet??
I Tried

rectangle.BORDER_PANEL
{
	background-color: #FF0000;
}

with and without the BORDER_PANEL bit, but no luck…

Also, whilst I am asking, is there a COMPLETE sample style sheet that includes every possible Servoy form item/object (maybe some kind of side by side screen shot of a Servoy form with the CSS style sheet for all of it)??

Thanks

Rafi
