  <h2>Migrating from A17 Tailwind Plugins 4 to A17 Tailwind Plugins 5</h2>

  <figure class="code-example">
    <figcaption class="code-example-filename">terminal</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-bash">npm install @area17/a17-tailwind-plugins@latest</code></pre>
  </figure>

  <h3>Ensure your <code>screens</code>, <code>mainColWidths</code>, <code>innerGutters</code>, <code>outerGutters</code> and <code>columnCount</code> are defined at all breakpoints</h3>

  <p>Previously you could define just the breakpoints where the gutters changed:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">tailwind.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">const { Setup } = require('@area17/a17-tailwind-plugins');

module.exports = {
  ...
  plugins: [Setup],
  theme: {
    screens: {
      xs: "0",
      sm: "544px",
      md: "650px",
      lg: "990px",
      xl: "1300px",
      xxl: "1520px"
    },
    mainColWidths: {
      xs: "auto",
      xxl: "1440px"
    },
    innerGutters: {
      xs: "10px",
      xxl: "40px"
    },
    outerGutters: {
      xs: "20px",
      sm: "30px",
      xxl: "0px"
    },
    columnCount: {
      xs: "4",
      sm: "4",
      md: "8",
      lg: "12",
      xl: "12",
      xxl: "12"
    },
  }
  ...
};</code></pre>
  </figure>

  <p>This was unintentional and no longer works, so you'll need:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">tailwind.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">const { Setup } = require('@area17/a17-tailwind-plugins');

module.exports = {
  ...
  plugins: [Setup],
  theme: {
    screens: {
      xs: "0",
      sm: "544px",
      md: "650px",
      lg: "990px",
      xl: "1300px",
      xxl: "1520px"
    },
    mainColWidths: {
      xs: "auto",
      sm: "auto",
      md: "auto",
      lg: "auto",
      xl: "auto",
      xxl: "1440px"
    },
    innerGutters: {
      xs: "10px",
      sm: "15px",
      md: "20px",
      lg: "30px",

      md: "40px",
      lg: "40px",
      xl: "40px",
      xxl: "0px"
    },
    columnCount: {
      xs: "4",
      sm: "4",
      md: "8",
      lg: "12",
      xl: "12",
      xxl: "12"
    },
  }
  ...
};</code></pre>
  </figure>


  <h3>Migrate Layout class names</h3>

  <p>See <a href="./Layout.html#v5-0-0">Layout/Breaking changes in <code>v5.0.0</code></a></p>

  <ol>
    <li>Search for <code>(\w*)-(\d\/\d|\d*)-cols(-no-gutter|-vw)?</code></li>
    <li>Replace with <code>$1-cols$3-$2</code></li>
  </ol>

  <p>And for any fraction class usage:</p>

  <ol>
    <li>Search for <code>(\w*)-(\d\/\d)-cols</code></li>
    <li>Replace with <code>$1-cols-$2</code></li>
  </ol>

  <h3>Migrate font family settings:</h3>

  <p>In your <code>frontend.config.json</code> you may have have had:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">frontend.config.json</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">"font-family": "var(--sans)",</code></pre>
  </figure>

  <p>Font classes now have a prepended <code>font-</code>. So, you'll need to update to:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">frontend.config.json</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">"font-family": "var(--font-sans)",</code></pre>
  </figure>

  <h3>Migrate any CSS in config JSON</h3>

  <p>You'll need to move any styles specified in your config to inside your CSS if you used these plugins.</p>

  <h2>Migrating from Tailwind 3 to Tailwind 4</h2>

  <p>Tailwind provide an <a href="https://tailwindcss.com/docs/upgrade-guide" target="_blank">upgrade guide</a>, you may need to do a mix of automatic and manual updates. Check those <a href="https://tailwindcss.com/docs/upgrade-guide#changes-from-v3">changes from v3</a> class name renames and removals.</p>

  <h3>Remove <code>tokens</code> from <code>spacing</code> in the config JSON</h3>

  <p>You no longer require the Spacing tokens plugin or setup:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">frontend.config.json</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">"tokens": {
    "scaler": 4,
    "arbitraries": {
      "400": "400px",
      "600": "600px"
    }
  },</code></pre>
  </figure>

  <p>Instead you add:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">input.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">@theme {
  --spacing: 1px;
}</code></pre>
  </figure>

  <h3>Confirm updates to your tailwind.config.js, input.css and postcss.config.js</h3>

  <figure class="code-example">
    <figcaption class="code-example-filename">tailwind.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">{% include_relative tailwind.config.js %}</code></pre>
  </figure>

  <figure class="code-example">
    <figcaption class="code-example-filename">input.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">@config "./tailwind.config.js";
@import "tailwindcss";

@theme {
  --container-*: initial;
  --breakpoint-*: initial;
  --color-*: initial;
  --font-*: initial;
  --text-*: initial;
  --tracking-*: initial;
  --leading-*: initial;
  --spacing: 1px;
}

@utility container {
  max-width: 100%;
}</code></pre>
  </figure>

  <figure class="code-example">
    <figcaption class="code-example-filename">postcss.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">{% include_relative postcss.config.js %}</code></pre>
  </figure>

  <h3>Vite config</h3>

  <p>If you're using Vite, you'll want to swap to <code>import tailwindcss from '@tailwindcss/vite'</code> and not use post CSS to compile, so you'll end up with a <code>vite.config.js</code> something like:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">vite.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">import eslintPlugin from '@nabla/vite-plugin-eslint'
import tailwindcss from '@tailwindcss/vite'
import laravel from 'laravel-vite-plugin'
import { resolve } from 'path'
import { defineConfig } from 'vite'
import dynamicImport from 'vite-plugin-dynamic-import'
import environmentPlugin from 'vite-plugin-environment'
import manifestSRI from 'vite-plugin-manifest-sri'

export default ({ mode }) => {
    return defineConfig({
        server: {
            host: 'sitename.test'
        },
        plugins: [
            tailwindcss(),
            dynamicImport(),
            eslintPlugin(),
            environmentPlugin({
                MODE: mode,
                BEHAVIORS_PATH: resolve(
                    __dirname,
                    'resources/frontend/scripts/behaviors'
                ),
                BEHAVIORS_EXTENSION: 'js'
            }),
            laravel({
                input: [
                    resolve(__dirname, 'resources/frontend/styles/app.css'),
                    resolve(__dirname, 'resources/frontend/scripts/app.js')
                ],
                refresh: true
            }),
            manifestSRI()
        ],
        resolve: {
            alias: {
                '@': resolve(__dirname, 'resources/frontend'),
                '@root': resolve(__dirname, './'),
                '@vitrineUI': resolve(__dirname, 'vendor/area17/vitrine-ui'),
                '@vitrineUIComponents': resolve(
                    __dirname,
                    'vendor/area17/vitrine-ui/resources/views/components/'
                )
            }
        }
    })
}</code></pre>
  </figure>

  <h3>Stylelint</h3>

  <p>You may also want to update your <code>stylelint.config.js</code>:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">stylelint.config.js</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-javascript">{
    "extends": ["stylelint-config-standard", "stylelint-config-clean-order"],
    "rules": {
        "custom-property-pattern": null,
        "at-rule-no-unknown": [
            true,
            {
                "ignoreAtRules": [
                    "config",
                    "custom-variant",
                    "source",
                    "theme",
                    "utility",
                    "variant"
                ]
            }
        ],
        "at-rule-no-deprecated": [
            true,
            {

            }

        "function-no-unknown": [
            true,
            {

            }
        ],
        "no-descending-specificity": null
    },
    "ignoreFiles": [
        "node_modules/**/*",
        "public/build/**/*"
    ]
}</code></pre>
  </figure>

  <h3>Migrate classes</h3>

  <p>And then you'll have fun migrating classes. For example:</p>

  <ul>
    <li>Arbitrary spacing using a pixel value doesn’t work anymore. Replace <code>left-[-99999px]</code> with <code>-left-99999</code></li>
    <li><code>flex-shrink-0</code> has been replaced by <code>shrink-0</code></li>
  </ul>

  <p>Tailwind has a list of <a target="_blank" href="https://tailwindcss.com/docs/upgrade-guide#renamed-utilities">renamed utilities.</a> and some <a target="_blank" href="https://tailwindcss.com/docs/upgrade-guide#removed-deprecated-utilities">removed utilities</a>.</p>

  <h3>Migrate CSS</h3>

  <p>If you have any CSS in your project, you may want to update to use <code>@utility</code> and <code>@layer components {}</code></p>

  <p>For example:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">effect.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">.effect-hidden-fade {
  @apply pointer-events-none invisible opacity-0;

  will-change: opacity, visibility;
  transition:
      opacity 300ms cubic-bezier(0, 0, 0.58, 1) 50ms,
      visibility 0s 351ms;
}</code></pre>
  </figure>

  <p>becomes:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">effect.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">@utility effect-hidden-fade {
  @apply pointer-events-none invisible opacity-0;

  will-change: opacity, visibility;
  transition:
      opacity 300ms cubic-bezier(0, 0, 0.58, 1) 50ms,
      visibility 0s 351ms;
}</code></pre>
  </figure>

  <p>And:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">effect.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">.wysiwyg * {
    @apply f-body;
}

.wysiwyg h2,
.wysiwyg h3,
.wysiwyg h4 {
    @apply f-body font-bold text-balance mt-group-6;
}

.wysiwyg p {
    @apply text-pretty;
}</code></pre>
</figure>

  <p>becomes:</p>

  <figure class="code-example">
    <figcaption class="code-example-filename">effect.css</figcaption>
    <pre
      class="code-example-code"
    ><code class="language-css">@layer components {
    .wysiwyg * {
        @apply f-body;
    }

    .wysiwyg h2,
    .wysiwyg h3,
    .wysiwyg h4 {
        @apply f-body font-bold text-balance mt-group-6;
    }

    .wysiwyg p {
        @apply text-pretty;
    }
}</code></pre>
</figure>
