If your cards look very unique, you are likely using the Loop Grid widget. This allows you to design one card, and Elementor repeats it for all posts.
- Go to your Blog page in Elementor and click the post area.
- Look for an Edit Template button hovering over the first post card.
- Click it. You will now be editing just that one small box.
- Add/Move anything: You can drag a “Post Title” or “Featured Image” widget into that tiny box.
- Click Save & Back at the bottom. This will instantly update every card on your blog.
