Android Text and elements display error (Huawei)

Hi, I’ve recently been working on a website development and have experienced some troubles with elements and text display on Android mobiles (especially Huawei phones).

The elements are not placed correctly and the text appears much bigger, though it’s size is set in pixels. After searching for the solution, I can’t come up with anything.

Could somebody please help me out?
I’ve added 2 screen captures, one from an iPhone 7 and one from a Huawei.

here is the link to the website so you can look for yourself : www.offre-optique-perignon.com

Thanks for the help !
