Exported project does not work on Windows

I have built a website with Bloc and the experience is astounding so far. However, the site does not work properly on Windows machine.

This is my website: rexlow.github.io

One of my friends told me that the collapse navbar is not showing in their Chrome on windows and contents are displayed in a disorder manner.

It works totally fine on all my Apple devices.

Let me know if you wish to access the source file.
