Tailwind - The Utility-First CSS Framework

A project by Adam Wathan (@adamwathan), Jonathan Reinink (@reinink),
David Hemphill (@davidhemphill) and Steve Schoger (@steveschoger).

Welcome to the Tailwind config file. This is where you can customize
Tailwind specifically for your project. Don't be intimidated by the
length of this file. It's really just a big JavaScript object and
we've done our very best to explain each section.

View the full documentation at https://tailwindcss.com.

| The default config
|-------------------------------------------------------------------------------
|
| This variable contains the default Tailwind config. You don't have
| to use it, but it can sometimes be helpful to have available. For
| example, you may choose to merge your custom configuration
| values with some of the Tailwind defaults.

|-------------------------------------------------------------------------------
|
| Here you can specify the colors used in your project. To get you started,
| we've provided a generous palette of great looking colors that are perfect
| for prototyping, but don't hesitate to change them for your project. You
| own these colors, nothing will break if you change everything about them.
|
| We've used literal color names ("red", "blue", etc.) for the default
| palette, but if you'd rather use functional names like "primary" and
| "secondary", or even a numeric scale like "100" and "200", go for it.

  | want, naming them in whatever way you'd prefer for your project.
