To customize the content of your static home page in WordPress, go to Pages > All Pages, then find and click Edit on the page labeled "Home" (or whichever page you've set as the front page).
You can add or modify text, images, videos, and other content just like on any regular page. If you're using a page builder like Elementor, Beaver Builder, or WPBakery, you can design advanced layouts with drag-and-drop tools for more control over your homepage appearance.
