Responsive screen size has play when on small screen

Question

all.

I have read many threads, I however, am at an impass.

I have built a website with React, which I hope it is OK to link.

When I am on a mobile device, the screen can be moved around and shows white around the sides.

I have tried;

1. height: 100%
2. height:100vh
3. minHeight:100vh

It does not seem to stop it.

I would prefer, on mobile, if the screen was fixed and did not move around.

Home screen settings:

    <div style={{display:'flex',flexDirection:'column' ,alignItems:'center', width:'100%', minHeight:'100vh',backgroundColor:'black', padding:20}}>
        <Paper elevation={3} style={{display:'flex',flexDirection:'column', height:'95%', width:'90%', backgroundColor:'black',padding:10}}>

Any ideas?
