CSS-in-CSS

You've heard of CSS-in-JS. But Jess uses a newfangled amazing new technique called CSS-in-CSS.

Steps to making a .jess file:

1. Write some CSS.#

And save it as .jess

// myfile.jess
.my-header {
background: rebeccapurple;
padding: 2em 4em;
}

2. Build it#

jess myfile.jess

3. You're already done, there are no more steps#

(Okay, there are maybe a few more things to learn about Jess.)
