Wells
Use a well anywhere in a page to draw attention to information.
A well could easily be combined with the success and warning/alert paragraph text(link) to produce clear sucess/error message on forms.
Well default
Look i'm a well!
My default background colour is white, which makes me stand out.
Well grey background
I'm also a well and i'm well grey.
You can make my grey by adding the class 'well--grey'.
