hamburger menu, desktop and mobile

you can insert images to menus by opening on dashboard the menus.
Choose your main menu and insert again on top another home item – open that item with that little arrow besides each item and insert on label :
<img class="burger-logo avia_image" src="/wp-content/uploads/logo.png" />
the classes here are not necessary but makes it easier to select the item later.

to have this “menu logo ” not in the normal desktop menu view you can do now:

#avia-menu .only-burger  {
  display: none !important;
}
