Make Navbar Background Transparent

Hello everyone, I am editing the website http://www.iheartf1.co.uk the website is based in blogger and isnt far removed from the original template but am struggling with one element.
If you look at the website there is a black background to the navigation bar. This navbar is just a series of png's that are linked to where they need to go.

I have tried every code in the HTML box that the navbar is coded in but nothing has worked. I have searched in the site HTML for "navbariheartf1" which is what I called it and found the widget but nothing to do with background.

Please help, how do I remove the awful background leaving the nav bar as a standalone and not affecting the rest of the site...

 

On line 273 of your css style sheet you have
background: #141414 none repeat scroll 0
If you remove this then you will end up with a transparent backgroung
Also if you remove line 281

border-top: 1pxsolid#222222;
remove this will remove the borders, if you need anymore help let me know

 

Perfect!! I love it when a fresh pair of eyes helps you see the wood for the trees!! all done now thanks again

 

No problem glad i could help
