Hey @Shayinur,
Good job ,
People can't see your work because in your html file you haven't add a dot and slash to your css path files that why your css file doesn't work on live site just before your styles folder.
When you need to center an element like a div in your case you can used flexbox like you've done on your qr_code div then using the property justify-content : center , use align-items : center with min-height : 100vh to have your element center horizontaly and vertically.
It's very useful thing that someone learned me on one of my previous challenge.
You can learn more efficiently flexbox with this game if you liked this kind of learning :
