Hi Wayne and welcome to TG, your page size is 960 wide by 1000 px long and your black background does not cover it. Go to your page layers on the right of the page, unlock the page background and pasteboard background by clicking on the orange lock then click on your black page background and enlarge to the limits of the page. You might also want to consider changing your pasteboard background color to black or any other color by dragging your chosen color over the white background. Next you will need to move your items on your page to where you want them. You may also want to right click your mouse while on the page background then click web properties at the bottom, then click on the website tab at the top and then click on the clip to page edges at the bottom in the other box. This last step will permit you to push items further out but the item needs to be touching the page background box to show when you preview and publish. Let us know how you make out.

Ciao
