In this tutorial we're going to look into how we can use https://tailwindcss.com/ in your WordPress theme. If you don't already know Tailwind CSS is a highly customisable utility first CSS.
Normal WordPress theme development doesn't tend to use modern frontend development techniques such as https://www.npmjs.com/ and https://webpack.js.org/. In this tutorial we're going to setup our WordPress theme to use webpack to compile our CSS file which will use Tailwind with https://postcss.org/.
This will build you a new style.css file that WordPress can use on your theme.
