Improve look and feel of node edit forms

Suggestios applied, always room for improvements specially on styles.
Just taking note that this is a base theme, so just basic styles applied to base components

I agree there is always room to improvements, but the current look and featl very basic and makes most people just uninstalling it. :-) I do not like the word "base theme" in this context.

I think it can still look very modern and nice out of the box like Claro. This safes a lot of effort as developer do not need to design everything on thier own for no need. I think that was mainly the reason why I personally never switched to Bario theme.

Please try to make the theme look great out of the box like core themes.

Not sure why it is still not using the full width as the CKEditor really needs a lot of space.
