v9.7.0

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([email protected]);
}
@​media (min-resolution: 2dppx) {
  .image {
    background-image: url([email protected]);
  }
}

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

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.
• @​jmmarco added CONTRIBUTING.md

b {
  mask: url(intersect.png) intersect, url(exclude.png);
}

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

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.

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;

v9.2.0

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.

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.

.main {
    gap: 10px 20px;
    grid-template-columns: 1fr 1fr 1fr;
    grid-template-areas: "head head head"
                         "nav main main"

Autoprefixer 8.5 brings grid-gap support and fix radial-gradient.

Grid Gap

@​yepninja continues his amazing work of adding CSS Grid Layout support to Autoprefixer.

Now he brought grid-gap. It is amazing work since IE 11 has gaps support in -ms- grids.

To add grid-gap support for IE 11 Autoprefixer adds addition grid cells. Unfortunately, it will work only if you have grid-template in the same rule with grid-gap. We had big discussion with a community about these limits.

.page {
    grid-gap: 33px;
    -ms-grid-rows: 1fr 33px minmax(100px, 1fr) 33px 2fr;
    -ms-grid-columns: 1fr 33px 100px 33px 1fr;
    grid-template:
        "head head  head" 1fr
        "nav  main  main" minmax(100px, 1fr)
        "nav  foot  foot" 2fr /
        1fr   100px 1fr;
}

Set postcss-gap-properties before Autoprefixer if you want to use new gap property.

Radial Gradients

Old gradients with prefixes used a different direction syntax. Autoprefixer converts direction to old syntax (or warn you to rewrite direction from old to new syntax).

But it has an issue with extent keywords like circle closest-corner. We fixed it after @​BaliBalo report.

.mask {
    -webkit-mask-image: -webkit-radial-gradient(100% 50%, circle closest-corner, black, white);
            mask-image: radial-gradient(circle closest-corner at 100% 50%, black, white);
}

    mask: url(mask.jpg); /* ← will be prefixed */

Autoprefixer 8.3 adds @media support for grid-template and fixes gradient direction warning.

Media and Grid Layout

@​evgeny-petukhov continues his great work for Grid Layout support in Autoprefixer.

Now he improved @media support. Now this CSS will work in IE:

body {
    grid-template:
        [header-left] "head head" 30px [header-right]
        [main-left]   "nav  main" 1fr  [main-right]
        [footer-left] "nav  foot" 30px [footer-right]
        / 120px repeat(4, 250px 10px);
}

header {
    grid-area: head;
}

main {
    grid-area: main;
}

footer {
    grid-area: footer;
}

@​media (min-width: 1000px) {
    body {
        grid-template:
            [header-left] "head" 30px [header-right]
            [main-left]   "main" 1fr  [main-right]
            [footer-left] "footer" 30px [footer-right]
            / 1fr;
    }
}

Don’t forget that Autoprefixer inserts Grid Layout prefixes only if you set grid: true option.

Gradient Warning

@​radium-v found that Autoprefixer show warning even if cover is outside of radial-gradient.

a {
    background: radial-gradient(#fff, transparent) 0 0 / cover no-repeat #f0f;
}

@​kotfire improve old direction detection and fix this issue.

            color-adjust: exact;

Autoprefixer 8.1 brings overscroll-behavior and better Grid support.

Overscroll Behavior

@​Malvoz suggested the great idea to polyfill overscroll-behavior for IE 11 and Edge by -ms-scroll-chaining.

.none {
    -ms-scroll-chaining: none;
        overscroll-behavior: none;
}
.contain {
    -ms-scroll-chaining: none;
        overscroll-behavior: contain;
}
.auto {
    -ms-scroll-chaining: chained;
        overscroll-behavior: auto;
}

Note, that overscroll-behavior-x and overscroll-behavior-y are not supported since -ms- property doesn’t have this freedom.

Better Grid Layout

@​evgeny-petukhov continues his amazing work and now Autoprefixer polyfills Grid Layout for IE in more cases.

He added grid-template shortcut support and improve support of grid-column-end and grid-row-end.

Grid properties were fixed in @supports. We recommend:

• To select modern Grid browsers and IE 11: @supports (display: grid).
• To select only Grid browsers without IE 11: @supports (grid-gap: 0).

Note, that you need grid: true option to Autoprefixer to add -ms- prefixes for Grid Layout.

v8.0.0

Autoprefixer 8.0 uses Browserslist 3.0, has autoprefixer CLI tool instead of autoprefixer-info.

Browserslist 3.0

The main feature of Autoprefixer 8.0 is Browserslist 3.0. In the new version, it brings new default browsers. It will affect you only if you don’t change browsers by .browserslistrc or browserslist key in package.json (we don’t recommend to use browsers option).

In one hand, Browserslist 3.0 usage statistics limit for default browsers was reduced from >1% to >0.5%. In another hand, we remove dead browsers from default browsers. The dead browser is a browser with < than 1% in the global market and who don’t have security updates. Right now IE 10 and BlackBerry browser are dead browsers.

Read other notable changes in Browserslist 3.0 changelog. We recommend subscribing for @​Browserslist twitter account.

CLI Tool

CLI tool to show target browsers and used prefixes was renamed to autoprefixer:

$ npx autoprefixer --info
Browsers:
  Edge: 16

These browsers account for 0.04% of all users globally

At-Rules:
  @​viewport: ms

Selectors:
  ::placeholder: ms

Properties:
  user-select: ms
  hyphens: ms
  appearance: webkit
  scroll-snap-type: ms
  scroll-snap-coordinate: ms

  scroll-snap-points-x: ms
  scroll-snap-points-y: ms
  flow-into: ms
  flow-from: ms
  region-fragment: ms
  text-spacing: ms

With the new name, npx will install Autoprefixer automatically if it is missed in the current project.

Previous Autoprefixer versions replace break-* properties to page-break-* for Firefox.

But this feature didn’t add any vendor prefix. Autoprefixer goal is to take care only about prefixes, not polyfills. For better consistency, we removed this feature from Autoprefixer.

Don’t afraid, the PostCSS ecosystem has many plugins for CSS polyfills. We recommend to take look at postcss-preset-env to write future CSS today.
