What Does Above the Fold Mean?
The first space in your web page that appears on a screen before a visitor needs to start scrolling down. This can also be referred to as the bottom of a browser window or it can be measured as 600 pixels from the top of the page.
This term is borrowed from the world of print media, referring to the space above the fold in the mid-section of a newspaper that is visible on the newstand. Typically, this space includes the headline and a striking cover image to attract attention from readers.
