CSS

Looks good. I added this CSS to it, I pulled it from your live demo, to make sure that the menu slide-out menu buttons on mobile show properly (otherwise they have no background behind them).

#wrapper #nav-bar, #wrapper .menu ul.sub-menu, #wrapper .menu ul.children {
	background-color: #ffffff;	
}

@media screen and (max-width: 1024px){
	#menu-toggle svg {
		fill: rgba(0, 0, 0, 0.4);
	}
}
