Changing the header to black without the background changing

[storm]

I am using the technical template as a base and I am am trying to make the header where the background image and search bar sit have black as the background colour. I thought it would be possible because in the code it seems to be declared as a table however putting in "bgcolour=#000000" is having no effect no matter where I put it. I have tried to use fire bug to find something in the css with no luck. If someone could find some time to have a look at www.lowcostplumbingsupplies.co.uk and see if they can spot something Im missing I would appreciate it

why not just increase the width of your image to fill the space?

you could keep the words part as is. just increase the width of the image and fill the space with black.

Couldn't change image width because this messes up the search bar.

Thank you so much for taking the time to have a look at that for me I am still learning as I go and had no idea you could assign a color to a div tag. It works fine now, Thanks again.
