Floating Menu

Right now the header (logo + menu) is fixed. I assume this is a setting made by your theme or page builder. To make the header scroll out of sight as you scroll down the page you could either check if your theme or page builder has an option to unset the position to fixed or you could add the following CSS to override the fixed position and make it relative:

div#page-container.et-animated-content {
	padding-top: 0;
}
.et_fixed_nav #main-header, .et_fixed_nav #top-header {
	position: relative;
}
