Hello,
When you remove the inner elements (image, heading, button) from the Elementor Slides/Container, the content height naturally decreases because Elementor calculates the container height based on its content. That’s why your background image looks squeezed.
Select the Container (or Slide section) in Elementor.
In the Layout tab, set a Minimum Height (for example, 600px or full viewport height 100vh).
Layout > Height > Min Height or set Height = Fit to Screen if you want full height.
