Html5QrcodeScanner needs css fix

[mebjas]

The demo page running Html5QrcodeScanner has more modern UI because of existing dependencies in the webpage.

OTOH, without any existing css the UI is much primitive.

This gives an advantage that the UI of the scanner can implicitly match the theme of the website it's attached to.

Considering pros and cons - make minimal fixes to the style or alternatively make this configurable.

Hi mebjas, I really love your html5-qrcode.
I just write a simple CSS theme for it.

@Qiming-Liu Thanks for sharing this.

Additionally,
We need more of a UI overhaul as described in #207 which changes some of the existing issues, redundancies, internationalization issues and probably even allow developers to customize the style without having to implement on top of Html5Qrcode directly.

Looking forward to hear more feedbacks on this soon for designers/UXRs
