I can not remove the header or footer shading

Hi robertolex,

Here is the code you can put in Enfold > General Styling > Quick Css,  if it does not work, put into themes/enfold/css/custom.css

#top.avia-blank {
    background-color: #fff;
    border: none;
}
#top.avia-blank #wrap_all #main .container,
#top.avia-blank #wrap_all #main,
#top.avia-blank #main .container_wrap:last-child {
    border: none;
}

If you need further assistance please let us know.

Best regards,
Victoria
