(The body class for any given post or page can be found in that page’s source. You need to inspect the page’s source code and locate the body tag near the top. The tag is in there.)
Thanks for the extra details, let me rather assist with the exact task. I’m not following though, you have background images in the body and footer, the only area that is white is the header. It’s currently #ffffff; Are you looking to change the opacity of the header or change it’s color? Which page should I be looking at? I’m not seeing a link that says “more about bluehost”.
Thanks, just let me know about my above questions and I’m sure I’ll get this sorted for you shortly.
