Default form styles in mobile browsers

[halfmage]

I wanted to make an open discussion about if default browser styles should be integrated/used to reduce the amount of CSS or giving more focus on setting the styles for each browser the same.

1. Adding appearance: none to all form elements and updates the styles for each property e.g. border, box-shadow, outline, etc. Therefore the elements could be customized even more.
2. Just adding missing properties to override browser defaults
