As we mentioned above, Landing Pages have a few more layouts than other site templates. Here are some thumbnails of the layouts available to you along with the available zones, so you can decide which layout to use for your new page. Notice that some pages are designed not to scroll (those called "Simple") and will adjust to the height of the browser they're loaded on whenever possible. Most of the "Full" layouts have hero image sections based on the height of the browser (which is labeled "Viewport Height" on these thumbnails). You don't have to have content in all of the zones shown; they're simply available to you to make sure you can easily add any blocks to the page where you want them to lay out. Any of the layouts with two image placeholders will use both the Header Image and the Secondary Image you specify in the Page Attributes.
