Transparent menu on mobile.

Hi
As the title suggests:

Nothing i do is working, tried the following:

@media only screen and (max-width: 767px){
.html_header_top.html_header_sticky #top #wrap_all #main {
margin-top: -143px;
}
.responsive #top #wrap_all #header {
background: transparent;
}
AND:

@media only screen and (max-width: 767px) {
#top #wrap_all .av_header_transparency, .av_header_transparency #advanced_menu_toggle {
background: transparent!important;
position: absolute!important;
}}
