Leverage `!important` in Class Definitions

[alexlafroscia]

In the front-end guild meeting today, it was mentioned that we can't really use Tailwind classes to override default styles that are being applied from elsewhere.

Tailwind has the option to generate styles with !important, which would help with this.

!important shouldn't be necessary normally in Tailwind, but because we are introducing it to a legacy application, it would actually be a good fit for our use-case!
