Place the Title of a Page Under the Featured Image (instead of overlayed)

Typically, the title of a page will be displayed overlayed on top of the featured image (if one exists). If you’d like to leave the featured image as it is without the title over top of it, you can choose to display the title in the content area below the featured image.

Use the Page Options section near the bottom of the sidebar of the page editing screen, and change the value for Title Position from Overlayed on Featured Image to Below Featured Image.
