Parallax Background Image
Floating Content
This is a simple parallax effect which gives the page layout an illusion of depth by using semi transparent items on top of a full size background image.
The effect is enhanced by arranging the scroll speed of the background to be less than that of the content.
The widget only has three controls - for choosing the image, setting the percentage height and the scroll speed.
The widget obviously needs to be the first item inserted on the page. The Full Width box in the Metrics inspector is checked and the position Y is set to zero.
For short pages, the widget height can be set to the same as the content height. As the height is increased, so does the width od the image and, on long pages, this will result in a drop in image quality. In this case, increase the percentage height of the widget to a suitable value - anywhere beteen 100% and 200%. This needs to be done by trial and error to get the best result in terms of background coverage and image quality. After each adjustment, the result should be tested in the browser.
The scroll speed is then adjusted. Settings between 3 and 5 give good results.
This page layout has the transparent layer widget inserted after background and before the content widgets.
