Header padding / Content padding

Hi there,

My website:

http://www.whitestagweddings.com/

I have added some quick css:

.home .content { padding-top: 0px!important; }
.main_menu ul:first-child>li>a {
font-size: 9px;
}

to alter with the padding on the home page and the font size of the menu. In other pages, i.e. pricing (http://www.whitestagweddings.com/pricing/) i’d like to have the same padding but I can’t seem to get it to work?
Is there any way to alter my code or add code to get the padding to fit on all pages (very small padding between header and page content).

Thank you very much!

Andy
