v1.21.0

This release includes new features to improve compatibility of output CSS with your browser targets, and safely remove old fallbacks that aren't needed anymore. It also gives you more control over exactly how CSS is compiled, and fixes some bugs.

Preserve manual fallbacks

Lightning CSS will now preserve manually provided fallback values when some of your browser targets do not support the last one. For example, in the following rule, if some targets didn't support the max function, both declarations would be preserved. Otherwise, if we are sure that all targets support it, Lightning CSS will drop the fallback declaration.

.foo {
  margin-right: 22px;
  margin-right: max(4%, 22px);
}

This is supported for many types of values such as lengths, colors, gradients, images, font styles, etc. It uses compatibility data from caniuse and MDN to determine if each value is supported.

Include and exclude options

You can now control exactly how Lightning CSS compiles using the "include" and "exclude" options, in addition to the existing "targets". This allows you to explicitly turn on or off certain features, which overrides the defaults based on the provided browser targets. For example, you might want to only compile colors, and handle auto prefixing or other features with another tool. Or you may want to handle everything except vendor prefixing with Lightning CSS. These options make that possible.

An enum of available feature flags is provided, and you can use the bitwise OR operator to combine flags together, e.g. Features.Nesting | Features.Colors. There are also some flags which turn on multiple other flags at once, e.g. Selectors, Colors, and MediaQueries. The playground has been updated to show these flags and includes checkboxes to turn them on or off.

import {transform, Features, browserslistToTargets} from 'lightningcss';
import browserslist from 'browserslist';
transform({
// ...
// Turn on color and nesting compilation, regardless of browser targets.
include: Features.Colors | Features.Nesting,
</tr></table>
