I'm trying to change the colour or remove the word Entry(header) in the top left of my bigcartel http://pafclub.bigcartel.com/entry so the page is completely white. i want it to effect just this page without changing colours for other things on the other pages which is what happens when you use the default header colour changer.
The <body> tag gets a unique ID attribute for every page, so to target the page title (and hide it) only on your Entry page you can add a bit of CSS. Head to Customize Design > Advanced > CSS and add this code in at the very bottom:
#entry h1 { display: none }
