With these preset visual editor styles, the need to manually enter font sizes, colors, etc. should go away.
The use of manually selected font sizes, colors, etc. is not recommended as it typically leads to complexity, potential for inconsistent styling, and difficulty in management (since having all of the styles centralized in the theme allows for one update to affect all elements site-wide.) This styleguide may not take all conditions into account, but this should show the essential elements & widgets used throughout the site.
