Search

.navigation-search input[type="search"] {
	opacity: 1;
	font-size: 36px;
	text-transform: uppercase;
	font-weight: 900;
	text-align: center;
}

If the logo size was changed from GeneratePress default, use this code to expand the container height:

body nav:not(.is_stuck) .navigation-search input[type="search"] {
	height: 90px;
}
