PostCSS Double Position Gradients lets you use double-position gradients in CSS, following the CSS Image Values and Replaced Content specification.
```pcss .linear-gradient { background-image: linear-gradient(90deg, black 25% 50%, blue 50% 75%); }
.conic-gradient { background-image: conic-gradient(yellowgreen 40%, gold 0deg 75%, #f06 0deg); }
/ becomes /
.linear-gradient { background-image: linear-gradient(90deg, black 25%, black 50%, blue 50%, blue 75%); background-image: linear-gradient(90deg, black 25% 50%, blue 50% 75%); }
.conic-gradient { background-image: conic-gradient(yellowgreen 40%, gold 0deg, gold 75%, #f06 0deg); background-image: conic-gradient(yellowgreen 40%, gold 0deg 75%, #f06 0deg); } ```
Add PostCSS Double Position Gradients to your project:
bash
npm install postcss-double-position-gradients --save-dev
Use PostCSS Double Position Gradients to process your CSS:
```js const postcssDoublePositionGradients = require('postcss-double-position-gradients');
postcssDoublePositionGradients.process(YOUR_CSS /, processOptions, pluginOptions /); ```
Or use it as a PostCSS plugin:
```js const postcss = require('postcss'); const postcssDoublePositionGradients = require('postcss-double-position-gradients');
postcss([ postcssDoublePositionGradients(/ pluginOptions /) ]).process(YOUR_CSS /, processOptions /); ```
PostCSS Double Position Gradients runs in all Node environments, with special instructions for:
| Node | PostCSS CLI | Webpack | Create React App | Gulp | Grunt | | --- | --- | --- | --- | --- | --- |
The preserve
option determines whether the original double-position gradients
should be preserved. By default, double-position gradients are preserved.
js
postcssDoublePositionGradients({ preserve: false })
```css .linear-gradient { background-image: linear-gradient(90deg, black 25% 50%, blue 50% 75%); }
.conic-gradient { background-image: conic-gradient(yellowgreen 40%, gold 0deg 75%, #f06 0deg); }
/ becomes /
.linear-gradient { background-image: linear-gradient(90deg, black 25%, black 50%, blue 50%, blue 75%); }
.conic-gradient { background-image: conic-gradient(yellowgreen 40%, gold 0deg, gold 75%, #f06 0deg); } ```
The enableProgressiveCustomProperties
option determines whether the original notation
is wrapped with @supports
when used in Custom Properties. By default, it is enabled.
⚠️ We only recommend disabling this when you set preserve
to false
or if you bring your own fix for Custom Properties. See what the plugin does in its README.
js
postcssDoublePositionGradients({ enableProgressiveCustomProperties: false })
```pcss :root { --a-gradient: linear-gradient(90deg, black 25% 50%, blue 50% 75%); }
/ becomes /
:root { --a-gradient: linear-gradient(90deg, black 25%, black 50%, blue 50%, blue 75%); / will never be used, not even in older browser / --a-gradient: linear-gradient(90deg, black 25% 50%, blue 50% 75%); } ```
