I created a page using the Sydney Theme with an image as a header background. When I view the page, the screen looks as expected. But when I scroll down to see the lower part of the page, the image at the header is replaced with a black area.
When I scroll down the page, how can I remove the black area and leave the image at the header. Or better still, when I scroll down, the image scrolls up until it disappears giving me the whole screen to display the page content. Please Click here to see the issue.
