SharePoint modern pages are a great way to share ideas using images, documents, and web parts. You can create and publish pages quickly and easily, and they look great on any device. You can also make an existing page the home page for your site, even if you are using a SharePoint classic site. Here's how:
If you haven't already created a page, you can do so using the steps in Add a page to a site. When you have a published page you want to use for your home page, do the following:
On your site, click Pages in the left navigation. Or, if you don't see Pages, go to Site Contents on the left, and then Site Pages.
Click the circular option button to the left of the page you want to use as the home page.
Click the vertical ellipses (...) next to the page title, and then click Make homepage.
