Hello,
1) The wide layout has the container that has color. That’s why if you use wide layout (Theme Options > Layout > Wide) you can change the container color only. Or you may add the following custom CSS to make it transparent and show your site background
.page-wrapper {
background-color: transparent;
}
2) Icons color can be dark and white (Theme options > Header Settings > Header text color scheme). To change the back of the menu add the following custom CSS
@media (min-width: 991px){
.header-vertical .menu-main-container {
background-color: #845151;}
}
Upload bigger logo image to get bigger logo.
3) Go to (Theme options > Header Settings > Header bg). Bug with bg for the desktop version will be fixed in next theme update.
Regards
