I would like the main background on my website to be a gradient. I want all headers, menus, page content etc to be transparent and just sit over the gradient. I see that there are many posts regarding gradients and it seems the only way to do it is to dig in to code. That seems unbelievable that there is no gradient option integrated on the site builder.. I am complete novice and am intimidated by the coding aspect. What is my move here?
