Why is my website not rendering properly on laptops?

Can someone please check my website https://www.blancify.com/ . It is showing half sections for laptop , for mobile its appearing correctly. I’m unable to understand the problem.

Hi Aashish! Thankyou so much for quick response.

I did some code changes. But even if I reverse those changes, issue is still same. Can you please help me fix this issue.

@Albarkhan how did you fix it?
