Parallax scrolling refers to moving multi-layer backgrounds at different speeds to form a three-dimensional motion effect and bring a very good visual experience. As a hot trend in web design this year, more and more websites are applying this technology.
Don't understand can first look at the effect of eBay: http://www.ebay.com/new/
In fact, it is a fixed background that does not let it move with the scroll axis, but the container containing the background is rolling, resulting in visual differences that look like a conversion scenario. (Don't be confused about this explanation ...)
The backgroud-attacthment attribute that defines the background scrolling mode in CSS is
Background-Attachment-- Define how the background image is moved along with the scroll Element
- Value: Scroll | fixed | inherit
- Scroll: default value. The background image will move along with the rest of the page.
- Fixed: when the rest of the page is rolled, the background image will not move.
- Inherit: specifies that the background-attachment attribute settings should be inherited from the parent element.
- Initial Value: Scroll
- Inheritance: No
- Applicable to: All elements

Browser support:
Tested Chrome, opera, Safari, Firefox, ie7-8 is OK, so that IE6 can not ~
To use this attribute in IE6, You need to place background-Attachment: fixed in the body or HTML, that is, it is useless in other labels. The W3C above shows the effect because it is placed in the body.
