Compare Source

Autoprefixer 9.7 brings AUTOPREFIXER_GRID environment variable and huge performance improvments.

Grid Environment Variable

Autoprefixer can add CSS Grid polyfills for IE. You need to manually enable it to prove that you understand the limits of polyfill.

In previous versions you can enable Grid polyfill by grid: 'autoplace' option or by /* autoprefixer grid: autoplace */ control comment. But in some cases, developers were not able to use both methods. For instance, during work with Material UI’ CSS-in-JS in Create React App.

Now Autoprefixer supports environment variable to enable CSS Grid polyfill:

AUTOPREFIXER_GRID=autoplace npm build

Performance Improvements

@​Knagis found that Browserslist takes 70% of the Autoprefixer time.

We did a lot of improvements in Browserslist and now Autoprefixer should work much faster.

v9.6.0

Compare Source

Autoprefixer 9.6 marked browsers option as deprecated and added text-orientation and @media (min-resolution: 2x) support.

We added the “Sponsor” button to your repository. You can support Autoprefixer and other open source projects important for your business by Tidelift.

Browsers

Autoprefixer adds prefixes only for target browsers, browsers which is support on your project.

Initially, Autoprefixer had the browsers option to set target browsers. But we found that many tools need target browsers too. postcss-preset-env and babel-preset-env use them to add only actual polyfills, postcss-normalize uses them to add only necessary CSS reset rules, plugins for ESLint and Stylelint will warn you if some of the target browsers doesn’t support your code.

This is why we created Browserslist config file. It is a single config for all tools.

A lot of users still uses the browsers option. We understand them; it is hard to change old practice. Unfortunately, using the browsers option creates many problems. For instance, you can miss that your build tool has own Autoprefixer inside. It will cut your prefixes because it will not know about your target browsers.

This is why, in 9.6, we decided to deprecate the browsers option. Autoprefixer will show a warning on this option. In the next 10.0 release, we will drop this option. This is how you can migrate:

1. Create browserslist key with an array in package.json.

2. Copy queries from the browsers option. If you have browsers: [“last 1 version”, “not dead”], then you need:

      "browserslist": [
        "last 1 version",
        "not dead"
      ]

HiDPI Media Query

We all need to support HiDPI/retina screen now. Autoprefixer supports specific media query for HiDPI screens:

.image {
  background-image: url(image@1x.png);
}
@​media (min-resolution: 2dppx) {
  .image {
    background-image: url(image@2x.png);
  }
}

.image {
  background-image: url(image@1x.png);
}
@​media (-webkit-min-device-pixel-ratio: 2),
       (-o-min-device-pixel-ratio: 2/1),
       (min-resolution: 2dppx) {
  .image {
    background-image: url(image@2x.png);
  }
}

Bug we found that CSS Values 4 spec added x alias for dppx.

Autoprefixer 9.6 supports @media (min-resolution: 2x) shortcut. Note, that Autoprefixer will not convert it to 2dppx. Autoprefixer adds only prefixes. Use postcss-preset-env to add polyfills.

• text-orientation property support was added.

}

a {
  -webkit-mask-composite: source-over;
          mask-composite: add;
}
b {
  -webkit-mask: url(intersect.png), url(exclude.png);
  -webkit-mask-composite: source-in, xor;
          mask: url(intersect.png) intersect, url(exclude.png);
}

v9.4.0

Compare Source

Autoprefixer 9.4.0 brings limited autoplacement support to the IE CSS Grid.

Grid Autoplacement

If the grid option is set to "autoplace", limited autoplacement support is now added to the Autoprefixer CSS Grid translations. You can also use the /* autoprefixer grid: autoplace */ control comment to enable autoplacement directly in your CSS.

In order to use the new autoplacement feature, you must define both rows and columns when declaring the grid template.

/* Input CSS */

/* autoprefixer grid: autoplace */

.autoplacement-example {
    display: grid;
    grid-template-columns: 1fr 1fr;
    grid-template-rows: auto auto;
    grid-gap: 20px;
}

/* Output CSS */

/* autoprefixer grid: autoplace */

.autoplacement-example {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: 1fr 20px 1fr;
  grid-template-columns: 1fr 1fr;
  -ms-grid-rows: auto 20px auto;
  grid-template-rows: auto auto;
  grid-gap: 20px;
}

.autoplacement-example > *:nth-child(1) {
  -ms-grid-row: 1;
  -ms-grid-column: 1;
}

.autoplacement-example > *:nth-child(2) {
  -ms-grid-row: 1;
  -ms-grid-column: 3;
}

.autoplacement-example > *:nth-child(3) {
  -ms-grid-row: 3;
  -ms-grid-column: 1;
}

.autoplacement-example > *:nth-child(4) {
  -ms-grid-row: 3;
  -ms-grid-column: 3;
}

Autoplacement support in Autoprefixer is currently very limited in what it can do. Please read the Grid Autoplacement support in IE section before using this new feature.

Thanks to @​bogdan0083 for implementing the new feature, @​Dan503 for documenting it, and @​evandiamond for coming up with the initial idea.

Other Changes

• Remove some unnecessary warnings for Grid (by @​fanich37).

v9.3.1

• Fix Grid prefixes with repeat() value (by Bogdan Dolin).

v9.3.0

Autoprefixer 9.3 brings place-self support for Grid Layout

place-self

@​Dan503 and @​bogdan0083 found a way to impement support for another Grid property

.grid > .center {
  place-self: center;
}

.grid > .center {
  -ms-grid-row-align: center;
  -ms-grid-column-align: center;
  place-self: center;
}

Other Changes

@​Dan503 and @​bogdan0083 also detected and fixed issue with Grid row/column span inheritance.

v9.2.1

Compare Source

• Fix broken AST.

v9.2.0

Compare Source

Autoprefixer 9.2 brings many new improvements for -ms- prefixes for Grid Layout.

New Ways to Enable/Disable Grid Layout

In previous versions, you had needed to pass grid: true to enable prefixes for Grid Layout. But not all users have access to Autoprefixer options. CodePen, Create Reat App or Angular CLI doesn’t allow you to do it.

In Autoprefixer 9.2 @​fanich37 added special control comments:

/* autoprefixer grid: on */
.grid {
    display: grid;
    grid-gap: 33px;
    grid-template:
        "head head  head" 1fr
        "nav  main  main" minmax(100px, 1fr)
        "nav  foot  foot" 2fr /
        1fr   100px 1fr;
}

.non-ie .grid {
    /* autoprefixer grid: off */
    …
}

Autoprefixer doesn’t support Grid properties and values with auto. In 9.2 it will ignore whole @supports content if it contains these Grid properties:

@​supports (grid-auto-rows: 100px) {
    /* Autoprefixer will not show Grid warnings and will not add prefixes here */
}

Smarter grid-area

Autoprefixer supports grid-template even if it was not in IE Grid spec.

But in 9.2 @​bogdan0083 really improve it according to @​Dan503 idea. Now Autoprefixer supports even overriding grid-template.

/* autoprefixer grid: on */
.grid {
    display: grid;
    grid-template:
        "nav  main" minmax(100px, 1fr)
        "nav  foot" 2fr /
        100px 1fr;
}

.grid.no-menu {
    grid-template:
        "main" minmax(100px, 1fr)
        "foot" 2fr
}

Autoprefixer 9.1 brings background-clip: text and fix span in IE Grid.

Background Clip

background-clip: text become to be the standard and got Edge support. So we added it to Autoprefixer:

.title {
  background: linear-gradient(yellow, red);
   -webkit-background-clip: text;
           background-clip: text;
}

Note, that Edge expect -webkit- prefix for this property.

v9.0.0

Autoprefixer 9.0 brings Browserslist 4.0 and drops Node.js 4 support.

Breaking Changes

We removed Node.js 4 and Node.js 9 support since it doesn’t have security updates anymore.

We removed IE and “dead” browsers (without security updates) from Babel’s targets. Don't worry, Autoprefixer still generate IE-compatible code. These changes affect websites which run Autoprefixer on client-side like CodePen.

last 2 version
not dead
not Explorer 11
not ExplorerMobile 11
node 10
node 8
node 6

Autoprefixer Rails 9.0 dropped the RubyRacer and Sprockets 3 support.

Browserslist 4.0

Autoprefixer 9.0 uses Browserslist 4.0 to get your target browsers.

Now you use Browserslist to specify Node.js versions. Babel 7 will use Browserslist config as well.

Also, Browserslist 4.0 will warn you if you didn’t update Can I Use DB for last than 6 month.

PostCSS 7.0

Autoprefixer 9.0 uses PostCSS 7.0
