The full screen to minimised scroll effect requires some javascript (so please excuse any bad practice as javascript is not strength of mine). Here is what I use:
Code:
//find current viewport height and set jumbotron to that size (to make sure splash image always fills entire screen)
var h = Math.max(document.documentElement.clientHeight, window.innerHeight || 0);
$(".jumbotron").css("height", h);
//if window is resized, adjust the jumbotron height
$(document).ready(function () {
$(window).resize(function () {
var viewHeight = $(this).height();
$(".jumbotron").height(viewHeight);
}).resize();
});
//this is the main scroll function
$(window).scroll(function () {
if ($(document).scrollTop() > 20) {
$(".jumbotron").addClass("shrink");
$(".titles").addClass("shrinkMenu");
$("#clickableWrapper").remove();
} else {
$(".jumbotron").removeClass("shrink");
$(".jumbotron").css("height", Math.max(document.documentElement.clientHeight, window.innerHeight || 0));
$(".titles").removeClass("shrinkMenu");
}
});
As you can see, there are a bunch of rules for adding an removing CSS classes or setting CSS elements, so it should be a case of playing around with these and changing the setting to suit your requirements. At the very least you will need to add the following class to your global CSS (you can change the settings of this, height, margin etc., as you need):
Code:
.shrink {
height: 175px !important;
margin-top: 160px;
}
