Hi

Do you want to remove the header form all pages? Our theme wasn’t designed to hide header part of the page. However this can be achieved using this css in theme panel > custom code > custom css: http://screencast.com/t/8sopnVeJZRGE

.td-header-wrap{
display: none;
}

Thanks!

it works

thank you
