Title: Fix #8223 - revert changes introduced in b34847c213b49ae1698c4beccbec75b93d2f2860

@spicyj in b34847c213b49ae1698c4beccbec75b93d2f2860 introduced changes to styles (which are fine), and changes to plugging_in_values.html which completely break the exercise.

Rolling back the changes to `plugging_in_values.html`. I'm not sure what was the point of them, but I'm sure that now the exercise is working better :)
