Padding Issue with CSS Class on Individual Category Menu Item

Hi there,

I am trying to create a class to style a link at the top of my main menu. I simply want to change the background and have minimal padding (like a button). But it creates the color around the image the same height as the logo. I will paste the code here along with a screen shot.

.start-here {
background-color: #edcede;
border-radius:5px;
padding: 0 !important;
margin: 0 !important;
}
