properties-order

Specify the order of properties within declaration blocks.

This rule ignore prefixes to determine properties order. E. g. -moz-transform is treated as transform. But prefixed properties will always precede the unprefixed version (e. g. -moz-transform will be always before transform).

Recommended to use this rule only on source files, rather autoprefixed files. Some “non-standard” prefixes could be treated wrong. E. g. different flexbox implementations; -ms-flex-align: center; align-items: center; with alphabetical order will be sorted as align-items: center; -ms-flex-align: center; because alphabetically flex-align is after align-item.

This rule ignores variables ($sass, @less, --custom-property).

string|array: "alphabetical"|["array", "of", "unprefixed", "property", "names"]

"alphabetical"

Properties will be ordered alphabetically.

Before:

a {
	top: 0;
	color: pink;
}

a {
	-moz-transform: scale(1);
	transform: scale(1);
	-webkit-transform: scale(1);
}

After:

a {
	color: pink;
	top: 0;
}

a {
	-moz-transform: scale(1);
	-webkit-transform: scale(1);
	transform: scale(1);
}

["array", "of", "unprefixed", "property", "names"]

Within an order array, you should include unprefixed property names.

By default, unlisted properties will be placed after all listed properties. So if you specify an array and do not include display, that means that the display property can be included before or after all specified properties. This can be changed with the unspecified-properties-position option.

Given:

["transform", "top", "color"]

Before:

a {
	color: pink;
	top: 0;
}

a {
	-moz-transform: scale(1);
	color: pink;
	transform: scale(1);
	-webkit-transform: scale(1);
}

After:

a {
	top: 0;
	color: pink;
}

a {
	-moz-transform: scale(1);
	-webkit-transform: scale(1);
	transform: scale(1);
	color: pink;
}

Given:

[
	"position",
	"top"
	"display",
	"z-index"
]

Before:

a {
	z-index: 2;
	top: 0;

	position: absolute;
	display: block;
}

After:

a {

	position: absolute;
	top: 0;
	display: block;
	z-index: 2;
}

Note: Empty line before position is preserved.
