Controls whether a background image stays fixed in place or scrolls along with the content. 'fixed' is often used to create a simple parallax-like effect where the page content slides over a static image.
Quick example
.parallax-section {
background-image: url('stars.jpg');
/* Image stays put while the user scrolls */
background-attachment: fixed;
background-size: cover;
