Here's an example of three elements. This element is set to block, meaning it will break to the next line. This element is set to display inline, which is the default setting for text in HTML. As for the last container, I'm right here. You found me! you will need to look in the source code, as it's set to not display. Why have write something that doesn't display? Maybe you want only certain elements to display for certain outputs (print, handhelds, etc.)
