I am using BB and generatorPress and I have been using this in the css and it is working. Just make sure you have it commented out when you are working on it because you won’t be able to edit your top row in beaver builder if you are using that
/* Create transparent header that sits over the hero content */
@media (min-width:600px) {
.site-header {
z-index: 100;
position: absolute;
width: 100%;
}
nav#sticky-navigation {
background: rgba(0,0,0,0.3);
}
}
