You don't use codes for the custom pages. You either use the preset cafemom themes or upload your own images (jpg or gif) as background and change the colors of the boxes or tabs with a color wheel pop up. Click on privacy + settings at the top of the page and customize your page is about half down the menu. To use your backgrounds choose advanced customization in the middle of the page and it will take you the advanced page.
