ok thank you

Hello I am trying to do that but the function file is not letting me to insert any change…how can I do it?
Thank you, Carmen

Sorry! is not correct!
I mean that what I want is to have the top bar with the top menu, logo and burger menu fixed in the top, in desktop and mobile also. What I have now is:

} /* topmenu fixed en moviles*/

.html_header_top.html_header_sticky #header {
position: fixed !important;
min-height: 80px;
}

#advanced_menu_toggle, #advanced_menu_hide {
position: absolute !important;
right: 0;
}

#advanced_menu_toggle {
top: 45%;
}

#advanced_menu_hide {
top: 10%;
right: 10px;
}
.av-main-nav > li > a { padding: 0 5px; }

@media only screen and (max-width: 767px) {
.home #av_section_1 .av-special-heading-h1 {
padding-top:20px !important;
}
}

But is not fixed in the top, Looking for your comments, Thank you

Hello, maybe I dod not explain myself very well, my problem is not the width, is the high!
I you go to iomm.es in the iphone version, you can not read the fist phrase, is hidden under the area of the logo and the burger menu.
Looking for your comments, Thank you

Hello, I wanted to do the same, and I have use the code you indicated:

/* topmenu fixed en moviles*/

.html_header_top.html_header_sticky #header {
position: fixed !important;
min-height: 80px;
}

#advanced_menu_toggle, #advanced_menu_hide {
position: absolute !important;
right: 0;
}

#advanced_menu_toggle {
top: 45%;
}

#advanced_menu_hide {
top: 10%;
right: 10px;
}

But my problem is that the slider overlaps the area of the top menu : you can see it here: iomm.es

Thank you, Carmen
