Jparallax is a Jquery plugin which turns a selected image into a viewport, and all its other images into absolutely positioned layers that can be seen through the viewport. These layers move in response to the mouse, and, depending on their dimensions ,they move by different amounts, in a parallaxy kind of way.Steps for Integrating jParallax into Blogger
1.In the Blogger Dashboard , Go to Template > Edit HTML
2.Click once inside the Edit HTML Editor and then Press CTRL+F(Windows) or COMMAND+F(Mac) , A search box will appear in the right upper corner of the editor itself. Now search for this "</head>" (without quotes) and then paste the following JavaScript just Above it. (Check the Animated GIF to understand better )

3. Now search for the ]]><b:skin> in the template and copy the following CSS just Above it.
#parallax {
background:#ccc;
position:absolute;
overflow:hidden;
width:970px;
height:200px;
}
Note: The width and height depends on the dimensions of the images you are using
4.Now copy the following HTML markup where you want to use it
<div id="parallax">

This is a generic example and this can be used in a number of creative ways

Thanx for sharing this tips with us :)
Hi, I have trouble using Jparallax on Blogger, send me a template already implemented Jparallax.
