Suggestion for future people: Tailwind --postcss flag

[34638a]

Hey Yo,

Just a quick feature change suggestion to enable opacity flags in tailwind:
Change your tailwind watcher to npx tailwindcss -i assets/scss/tailwind.css -o assets/scss/tailwind.scss --watch --postcss

Create a postcss.config.js with content of:

module.exports = {
    plugins: {
        'postcss-import': {},
        tailwindcss: {},
        autoprefixer: {},
        'postcss-preset-env': {
            browsers: 'chrome >= 50', // configure a compatible browser version
        },
    },
}

These should be all the changes we made in terms of config for compiling to modify a store bought theme to enable tailwind with opacity. (you will need the plugins for postcss to be installed with npm still).

Hope this helps with the frustrations that are opacity. Thanks for making this repo open, it really helped us kickstart our tweaking.
