We should make sure these three scenarios work with whatever CSS we go with:

1. short label
2. something a little longer than normal
3. a really long supercalifragilisticexpialidocious label that maybe is something similar to a small paragraph of terms and conditions that a user might be asked to agree with by ticking the checkbox before proceeding
