This is my alternative to Nathan's shrinking header

shrink-header.css

.header {
	background-color:rgba(255, 255, 255, 0.7);
	position: fixed;

.hero-text {
	padding-top: 200px;

	height: 100px !important;
	width: auto;
	margin: 20px 0 10px 30px;
	float:left;
}
@media (max-width: 1041px){
		.logo{
			float:none;
			display:block;
			margin:20px auto;

}

    text-decoration: none;
}

shrink-header.js

jQuery(function( $ ){
