My Output :
The actual output:
Problem: The main problem here is that I cannot move the brown container behind the image as it completely covers my image . I want to show brown container behind the image such that it does not cover the face of the image.
Although I manage to do the task 90% how can I tackle this problem.

Answer 1

The z-index property in CSS specifies how elements overlap each other.
The z-index CSS property sets the z-order of a positioned element and its descendants or flex items. Overlapping elements with a larger z-index cover those with a smaller one.

Adding z-index: -999; to the image will make it move to the back.
