PostCSS Sass Extend

PostCSS Sass Extend is a PostCSS plugin that allows you to use @extend and placeholder classes like you do in Sass.

/* before */

%placeholder {
	color: blue;
}

%unused-placeholder {
	color: yellow;
}

.a {
	@extend %placeholder;

	background-color: black;
}

.b {
	color: red;
}

.c {
	background-color: white;

	@extend %placeholder;
}

.d {
	color: green;
}

/* after */

.a, .c {
	color: blue;
}

.a {

	background-color: black;
}

.b {
	color: red;
}

.c {
	background-color: white;
}

.d {
	color: green;
}
