There are a few things you can do to change the layout of a page in Photoshop. The first is to select the page you want to change and then use the Page Properties panel to set the properties of the page. The second is to use the Page Layout tool. This tool allows you to change the layout of a page by selecting one of several options, such as left-to-right, top-to-bottom, or left-to-left. The third is to use the rulers to create lines on a page and then use the Line tool to draw lines between these lines. Finally, you can use the Marquee tool to select areas on a page and then use them as backgrounds for images or other elements on the page.
