Conig postcss

  plugins: [require("tailwindcss"), require("autoprefixer")],
};

Add tailwind.css

// css/tailwind.css
@tailwind base;
@tailwind components;
@tailwind utilities;

Add scripts

  "scripts": {

Once you run npm run build, it will generate css file for you.

It looks like this:

  },
  plugins: [],
};

Utility

You can find all the utility class here

For example:

  <body class="bg-gray-100">
    <div class="px-8 py-12">
      <img class="h-10" src="/img/logo.svg" alt="Workcation" />
      <img
        class="mt-6 rounded-lg shadow-xl"
        src="/img/beach-work.jpeg"

      />
      <h1 class="mt-6 text-2xl font-bold text-gray-900 leading-tight">

      </p>
      <div class="mt-4">
        <a
          href="#"
          class="
            inline-block
            bg-indigo-500
            text-white text-sm
            px-5
            py-3
            rounded-lg
            shadow-lg
            uppercase
            tracking-wider
            font-semibold
          "
          >Book your escape</a
        >
      </div>
    </div>

Responsive

There are sm, md, lg, xl, prefix, if use without prefix, it apply to all screen size.

          <img
            class="
              mt-6
              rounded-lg
              shadow-xl
              sm:mt-8 sm:h-64 sm:w-full sm:object-cover sm:object-center
              lg:hidden
            "
            src="/img/beach-work.jpeg"
            alt="Woman workcation in beach"
          />

You can find the docs about responsive here

Conditionally sytle

Such as hover, focus, those are call variants

module.exports = {
  purge: [],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    backgroundColor: ["responsive", "hover", "focus", "active"],
    // for example you want to enable hover for the fontsize, normally you won't do that just an example
    // hover:text-2xl
    // fontSize: ['responsive', 'hover'],
    extend: {},
  },
  plugins: [],
};

We add backgroundColor to the config file, so that the conditional style can be add to background class:

            <a
              href="#"
              class="
                inline-block
                bg-indigo-500
                hover:bg-indigo-400
                focus:outline-none focus:ring
                active:bg-indigo-600
                text-white text-sm
                sm:text-base
                px-5
                py-3
                rounded-lg
                shadow-lg
                uppercase
                tracking-wider
                font-semibold
              "
              >Book your escape</a
            >

You can see the docs

@apply

Previously we have the a tag have lots of class:

            <a
              href="#"
              class="
                inline-block
                bg-indigo-500
                hover:bg-indigo-400
                focus:outline-none focus:ring
                active:bg-indigo-600
                text-white text-sm
                sm:text-base
                px-5
                py-3
                rounded-lg
                shadow-lg
                uppercase
                tracking-wider
                font-semibold
              "
              >Book your escape</a
            >

We want to use @apply to make custom class name with those classes

in css/tailwind.css

@tailwind components;
.btn {
  @apply inline-block
    px-5
    py-3
    rounded-lg
    uppercase
    tracking-wider
    font-semibold;
}
.btn:focus {
  @apply outline-none ring;
}

.btn-indigo {
  @apply bg-indigo-500 text-white;
}
.btn-indigo:hover {
  @apply bg-indigo-400;
}
.btn-indigo:active {
  @apply bg-indigo-600;
}
@tailwind utilities;
   <a href="#" class="btn btn-indigo sm:text-base shadow-lg">Book your escape</a>

We didn't apply shadow-lg and sm:text-base because different button might have different looking & feel.

Customizse

You can find docs here

You can generate a full configure file to have a look

npx tailwind init tailwind-full.config.js --full, it is a good reference to have a look what you are able to config.

For example, we want to add a new color or spacing:

  theme: {
    // what inside extend will extend default tailwind config
    // what outside extend will override default tailwind config completely
    extend: {
      colors: {
        "brand-blue": "#1992d4",
      },
      spacing: {
        72: "18rem",
      },
    },
  },

Remove unused css
