Lit components file

Processes Lit components specified by include and exclude in rollup.config.js. To use tailwindcss, put // tailwindcss in the first line of the css string.

import { html, css, LitElement } from "lit";
import { customElement } from "lit/decorators.js";

@customElement("simple-footer")
export class SimpleComponent extends LitElement {
  static styles = css`
    // tailwindcss
    // 👆 must set the above line on the first line of css string to use tailwindcss.
    .dummy {
      @apply text-red-500; // can use @apply and other tailwind derectives
    }
  `;

  render() {

      Hello, world!
    </h1>`;
