Add more linting rules to stylelintrc

Description

Progressively add more styling rules to the stylelintrc file

Since there are so many tiny linting errors, they should be fixed one at a time.
Only some of the rules in the user guide will be used.

Rules: https://github.com/stylelint/stylelint/blob/master/docs/user-guide/rules.md#possible-errors
