Need Help! Bug on touch device in my website project

So I’m making a website project for my school class, but there is a bug when we open the site on a touch device.

I want you to ask something about the page, are you feel hard when scroll down the page on a touch device?
If yes that is the bug.

So does anyone know how that bugs can occur? I would appreciate it if anyone knows how the bug can occur

This is the website.
The scss file
The html file

Thank you.

I didnt feel something weird as you said above. I just see something bug with design, your button Yes, Please! and text above that.
