Used Jquery for funtionalities

What challenges did you encounter, and how did you overcome them?

Using 2 divs with specific heights as per required design. Used a mai n div with height of 100vh and then distributed height in 4:6 ratio for both child divs giving display flex to the parent div. I did it in this way, any other solution or feedbacks are welcome.
