Simple technique Parallax Scrolling

Good day dear habrayuzer. To date, Parallax Scrolling is a kind of trend and I want to talk about a simple implementation of this effect. The technique is based on the rate of change of the background-position property. The effect of Parallax Scrolling is that the background moves slower than the content.

HTML markup

Create two blocks "data-type" "data-speed" :
<section id="home" data-type="background" data-speed="10" class="pages"> <article> Parallax Scrolling</article> </section> <section id="about" data-type="background" data-speed="10" class="pages"> <article> Parallax Scrolling</article> </section>
JavaScript, data-type .


CSS
id #home #about
#home { background: url(home-bg.jpg) center 0 repeat fixed; min-height: 1200px; } #about { background: url(about-bg.jpg) center 0 no-repeat min-height: 1200px; }
home-bg.jpg
