Hi @mnopstuv5000,

Welcome to the forum.

First problem to fix is the path to style.css. Once the path corrected then run validate the page by pasting your link into the following validator:

http://validator.w3.org/

i did the style.css thing now it looks like this http://www.thatsmarisa.com/fanlist/
the designer that design the layout sent me the header and background images too
he said to "in your root folder/fanlist folder add the files I sent you for the design (images and all the .php ones)
the images to background and header is header.png and bg.png i had upload them to my ftp but they dont show on the site
what do i do

why is my header and background images(header.png and bg.png)
not appearing on my site.
want should i do to make them appear
someone tell me reply back as soon as possible
http://thatsmarisa.com/fanlist this is the site page where im trying to get it to appear

There’s something very dodgy about your setup. Your image links lead to whole pages of content.
