CSS Job by JayPazos

We have an Amazon Webstore and this would be our first small project. We need a CSS implementation for the following functionality: 1) For the Site Navigation Widget make the background transparent so that the menu buttons don't look framed in a color background 2) Eliminate the small space at the top of the website Amazon seller suport has informed us that both functionality can be done with CSS. Since we don't know CSS we want to subcontract it This is our first freelancer project and want also to learn how to subcontract. We know this is very very small but want to learn first
