How to make the hoem page content have a white background

Hi,
I have published the featured article on the home page in the main_body position but the text does not have a white background. Can you please tell me how I can make the background of the main_body content to have white background?
Thank you for your prompt reply!
Kind regards

Please edit: /templates/gk_sho_and_buy/css/override.css and add at its end:

Code: Select all

#gkMainbody {
    background: #fff;
    margin: 0 7px 0 -7px;
    padding: 10px;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}


Remember to enable "CSS override" in template settings - advanced section.
