SETTING BACK COLOR ON WEB OBJECTS

I am trying to come to grips with the web site creation IDE in Xojo. I cannot seem to be able to set the back colour (colour) of the label or rectangle objects in the designer. I tried to add a style object to the project to see if I could get some CSS functionality through this, but it doesnt have any selection for colour. The help file on the style object has scant information on the subject. Any suggestions or advice would be appreciated

Just found out how to do it
