postcss-matches-is-pseudo-class v1.0.1

postcss-matches-is-pseudo-class

PostCSS plugin which converts :matches() pseudo classes into :is() and reverse.

By default:

.foo:matches(:hover, :active) {
  text-decoration: underline;
}

.bar:is(:hover, :active) {
  text-decoration: underline;
}

becomes

.foo:matches(:hover, :active) {
  text-decoration: underline;
}

.foo:is(:hover, :active) {
  text-decoration: underline;
}

.bar:matches(:hover, :active) {
  text-decoration: underline;
}

.bar:is(:hover, :active) {
  text-decoration: underline;
}

options

preserve

• With { preserve: true } (default), both :is() and :matches() are kept/added
• With { preserve: false }, renames :matches() to :is()
• With { preserve: "matches" }, renames :is() to :matches()
