CSS
Now add background image to the each container with a specific height. Then use the background-size: cover to create the actual parallax effect. The other background properties are used to center and scale the image perfectly.

JS
Now add some utility on your Parallax template like smooth scrolling and back to top button to make it more awesome.
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 700);
return false;
}
}
});
});
/*
Back to top scroll button.
*/
if ($('#back-to-top').length) {
var scrollTrigger = 100, // px
backToTop = function() {
var scrollTop = $(window).scrollTop();
if (scrollTop > scrollTrigger) {
$('#back-to-top').addClass('show');
} else {
$('#back-to-top').removeClass('show');
}
};
backToTop();
$(window).on('scroll', function() {
backToTop();
});
$('#back-to-top').on('click', function(e) {
e.preventDefault();
$('html,body').animate({
scrollTop: 0
}, 700);
});
}
