Sticky Navigation Menu Button CSS

/*Changes sticky navigation bg color on mobile menu */

.main-navigation.navigation-stick{
	background-color: #00aab0;
	height: 50px;
}

The first one I can get to work. I am unsure of how to reference the toggle menu button. I hope the code below somewhat explains what I'm trying to do

/*Float sticky navigation toggle button right and center vertically*/

.main-navigation.navigation-stick.menu-toggle {
	float: right;
	vertical-align:middle;
}
