Background Design Ideas – Using the Z background Property

You can use the z background property to make an html background image appear above the content. This makes it easier to use an image as a navigation bar because the nav will sit on top of the background image. This will keep the content visible. For example, you can put a large z background on a small page. You can change this value to match the size of your website. In other words, you can put a nav bar over the content.
