When you create a page, a default page layout is chosen for you, but you can select the one that meets your need.
A Page Layout is a pre‐defined "template" that controls the overall look and feel of a Web page. There are several "out‐of‐the‐box" page layouts available for welcome pages and other pages.
After your page has been created, you can switch the page layout via the Page Settings option from the Page menu located in the Page Editing Toolbar.
