Parallax scrolling is a technique that makes the background image behind a post stand still as the page scrolls, creating an illusion of depth and animation. Parallax Scrolling can only be applied when you add an image background to a row and is available on most post types.
STEP 1 - While logged in, hover over the post you would like to edit, and click on the "row" option.
STEP 2 - Next to "Background", click on the "add image" option and choose the image you would like to use for the row background.
Remember Parallax Scrolling can only be applied when you have an image present.
STEP 3 - Check the "Parallax Scrolling" option. You can also adjust the Overlay Color and Opacity. Click "OK" to save you changes.
