Compile CSS from components that require it

When working on this issue: #42 (closed) (MR: !36 (closed))

I noticed that 2 components use import from './some_styles.css' inside their components directly. Which causes the test task to fail, since jest doesn't know what to do with that CSS.

I tried the following plugins to no avail

The components that use this are

  • alert
  • dropdown
