v1.0.0-beta.1

Tailwind CSS v1.0.0-beta.1

It's here! 🎉

This release of Tailwind focuses mostly on changing things from 0.x that I would have done differently had I known where the feature set would be at today in advance.

So while there's not a ton of exciting new features, you can at least be excited about the fact that we now have a really stable base to build on, and that very soon we'll be out of the unpredictable pre-1.0 phase so you can feel comfortable using Tailwind in production if the 0.x label gave you pause.

• New config file structure: #637, Sample
• New expanded default color palette: #737
• New default maxWidth scale: #701

Update Tailwind

While v1.0 is still in a pre-release state, you can pull it in to your project using npm:

npm install tailwindcss@next --save-dev

Or using Yarn:

yarn add -D tailwindcss@next

Update your config file

Impact: All users, Effort: Moderate

This is really the big change in v1.0 — you can read all about the new config file format and motivation behind it in the initial pull request.

The new general config structure looks like this:

module.exports = {
  prefix: '',
  important: false,
  separator: ':',
  theme: {
    colors: { ... },
    // ...
    zIndex: { ... },
  },
  variants: {
    appearance: ['responsive'],
    // ...
    zIndex: ['responsive'],
  },
  plugins: [
    // ...
  ],
}

See the new default config file for a complete example.

There are a lot of changes here but they are all fairly cosmetic and entirely localized to this one file, so while it may look intimidating it's actually only 10-15 minutes of work.

1. Move all design-related top-level keys into a new section called theme.

   Every key except options, modules, and plugins should be nested under a new theme key.

   Your config file should look generally like this at this point:

     let defaultConfig = require('tailwindcss/defaultConfig')()
   
     let colors = {
       // ...
     }
   
     module.exports = {
   -   colors: colors,
   -   screens: {
   -     // ...
   -   },
   -   // ...
   -   zIndex: {
   -     // ...
   -   },
   +   theme: {
   +     colors: colors,
   +     screens: {
   +       // ...
   +     },
   +     // ...
   +     zIndex: {
   +       // ...
   +     },
   +   },
       modules: {
         appearance: ['responsive'],
         // ...
         zIndex: ['responsive'],
       },
       plugins: [
         require('tailwindcss/plugins/container')({
           // ...
         }),
       ],
       options: {
         prefix: '',
         important: false,
         separator: ':',
       }
     }

2. Rename modules to variants.

   "Modules" was a word we just kinda grabbed because we needed something, and we wanted to use that section of the config to both specify variants and disable modules if necessary.

   Now that all of Tailwind's internal "modules" are actually just core plugins, I've decided to deprecate this terminology entirely, and make this section of the config purely about configuring variants for core plugins.

   After making this change, your config file should look like this:

     let defaultConfig = require('tailwindcss/defaultConfig')()
   
     let colors = {
       // ...
     }
   
     module.exports = {
       theme: {
         // ...
       },
   -   modules: {
   +   variants: {
         appearance: ['responsive'],
         backgroundAttachment: ['responsive'],
         backgroundColors: ['responsive', 'hover', 'focus'],
         // ...
         zIndex: ['responsive'],
       },
       plugins: [
         require('tailwindcss/plugins/container')({
           // ...
         }),
       ],
       options: {
         prefix: '',
         important: false,
         separator: ':',
       }
     }

3. Move your options settings to the top-level.

   The advanced options have been moved to the top-level of the config file instead of being nested under the redundant options key.

   After making this change, your config file should look like this:

     let defaultConfig = require('tailwindcss/defaultConfig')()
   
     let colors = {
       // ...
     }
   
     module.exports = {
   +   prefix: '',
   +   important: false,
   +   separator: ':',
       theme: {
         // ...
       },
       variants: {
         appearance: ['responsive'],
         backgroundAttachment: ['responsive'],
         backgroundColors: ['responsive', 'hover', 'focus'],
         // ...
         zIndex: ['responsive'],
       },
       plugins: [
         require('tailwindcss/plugins/container')({
           // ...
         }),
       ],
   -   options: {
   -     prefix: '',
   -     important: false,
   -     separator: ':',
   -   }
     }

4. Update the sections under theme to their new names.

   As part of an effort to make the naming in the config file more consistent, many of the sections under theme have been renamed.

   These are the sections that need to be updated:

New Features

Registering new variants from plugins (#505)

(Introduced as an experiment in v0.6.2, now promoted to an official feature)

Plugins can now add their own variants (like hover, focus, group-hover, etc.) to Tailwind.

To get started, destructure the new addVariant function from the object passed to your plugin, and call it with the name of the variant you'd like to add and a callback that can be used to manipulate the PostCSS nodes where the variant is being applied:

module.exports = {
  plugins: [
    function({ addVariant }) {
      addVariant('important', ({ container }) => {
        container.walkRules(rule => {
          rule.selector = `.\\!${rule.selector.slice(1)}`
          rule.walkDecls(decl => {
            decl.important = true
          })
        })
      })
    }
  ]
}

Documentation is coming soon, but for now learn more in the pull request.

Variant order can be customized per module (#505)

(Introduced as an experiment in v0.6.2, now promoted to an official feature)

Variants are now generated in the order that they are specified in the modules section of your config file, rather than in a hard-coded static order like in previous versions of Tailwind.

That means that if you want focus variants to defeat hover variants for background colors, but you want the opposite behavior for border colors, you can actually do that now by specifying the order in your config:

modules.exports = {
  // ...
  modules: {
    // ...
    backgroundColors: ['responsive', 'hover', 'focus'],
    // ...
    borderColors: ['responsive', 'focus', 'hover'],
    // ...
  }
}

Note that this doesn't affect responsive variants — those are a special case since responsive versions are also generated for other variants, and we group responsive declarations to optimize the resulting CSS.

Added focus-within variant (#463)

Tailwind now includes a focus-within variant that you can use to change how an element is styled if an element inside of it has focus.

<div class="focus-within:shadow-lg">
  <label>
    <span>Email</span>
    <input type="email">
  </label>
</div>

Learn about the :focus-within pseudo-class on MDN

By default we don't generate focus-within variants for any utilities, but you can change this in the modules section your Tailwind configuration file:

  modules.exports = {
    // ...
    modules: {
      // ...
-     backgroundColors: ['responsive', 'hover', 'focus'],
+     backgroundColors: ['responsive', 'focus-within', 'hover', focus'],
      // ...
    }
  }

Fancy CLI updates (#554)

Tailwind 0.7.0 includes a completely rewritten CLI tool with nicer output and a better user experience.

All of the existing functionality is still there with the same API, it just looks better.

Option to generate config without comments (#558)

You can now use the --no-comments option when running tailwind init to generate a config file that excludes all of the inline documentation comments.

This is a great way to make your config file easier to skim if you're an experienced Tailwind user who doesn't need the comments.

Make configured prefix optional when using @apply (#553)

If you're prefixing your generated utilities, including that prefix when using @apply is now optional.

/* Before */
.my-component {
  @apply tw-bg-blue tw-text-white tw-font-bold;
}

/* Now */
.my-component {
  @apply bg-blue text-white font-bold;
}

You can continue to use the prefix if you like, or drop it if you prefer a terser syntax.

Improve Flexbox behavior in IE 10/11 (#550)

IE 10 and 11 interpret the shorthand flex property differently than other browsers.

Tailwind now specifies explicit grow, shrink, and basis values for the flex-1, flex-auto, and flex-initial utilities for a more consistent cross-browser experience.

Learn more at the flexbugs repo (bugs #4 and #6 specifically)

Changes

Variant order in modules config is now significant (#505)

Impact: Low, Effort: Low

Prior to 0.7.0, variants were always generated in the same order, regardless of the order specified in the modules section of your config file.

Now, variants are generated in the they are specified. That means that if your config file currently lists variants in a different order than the <=0.6.6 default variant order, those variants will appear in a different order in your CSS.

To preserve the <=0.6.6 behavior, simply edit the modules section of your config file to make sure your variants are listed in the following order:

modules.exports = {
  // ...
  modules: {
    // ...
    [anyModule]: ['group-hover', 'hover', 'focus-within', 'focus', 'active']
    // ...
  }
}

Normalize.css updated to v8.0.0 (#537)

Impact: Low, Effort: Low

We've updated our dependency on Normalize.css from 7.0.0 to 8.0.0.

This drops support for very old browsers like IE9, Android 4.3, Safari 8, and iOS Safari 7-8.

If you still need to support those browsers, remove @tailwind preflight from your CSS, add Normalize.css 7.0.0 to your project, and manually add our additional preflight base styles.

Removed CSS fix for Chrome 62 button border radius change (#579)

Impact: Low, Effort: Low

When Chrome 62 was released, it introduced a user agent stylesheet change that added a default border radius to all buttons.

This messed up styles for like half of the internet (including sites like GitHub itself), so Chrome reverted the change in Chrome 63.

We included a fix for this in Tailwind with the intention to remove it when Chrome 62 was no longer in common use. Now that usage has dropped to 0.09%, we've removed our fix.

If this is a problem for you (it isn't), you can add the removed styles back to your project right after @tailwind preflight.
