}
.foo {
/* Output example */
background: linear-gradient(to bottom, #1e5799, #7db9e8);

}
Install
npm install postcss-filter-gradient --save-dev
Usage
postcss([ require('postcss-filter-gradient') ])
Options
angleFallback
Default: true
IE filter doesn't support angular gradient. By default, when processing the angular gradient,
we will convert the angle to its closest direction. You can disable this feature by setting this option to false
.
Limitation
The IE filter gradient only support horizontal and vertical directions, and only support two colors. So, if there are more than two colors in the color stops, we only pick the first and the last one.
FAQ
Does it support legacy gradient syntax?
No. We only transform the standard linear-gradient
syntax.
You can use the postcss-gradientfixer to unprefix it first.
Does it support angluar gradient?
Yes. This plugin only support deg
unit. It will convert angular to the closest direction. For example, it convert 90deg
to right
and convert 10deg
to top
, positive angluar are also supported.
