Quantity Queries mixins

npm version Test

Simple quantity queries mixins for Sass. Use quantity as a condition to style your items. Learn more about quantity queries in this A List Apart article. See the mixins in action in this CodePen Demo

Mixin item quantity matching examples:

1 item 2 items 3 items 4 items 5 items 6 items
at-least(4)
at-most(4)
between(3, 6)
exactly(5)
even()
odd()
multiple-of(3)

Install

Using npm:

npm install --save-dev quantity-queries

Using Yarn:

yarn add --dev quantity-queries

Usage

Import the library:

// Dart Sass
@use 'quantity-queries';
// LibSass
@import 'quantity-queries/legacy';

Note: depending on your setup you might need to use the node_modules path for the import.

// Dart Sass
@use '{node_modules_path}/quantity-queries/src/';

// Legacy implementations (e.g., node-sass)
@import '{node_modules_path}/quantity-queries/src/legacy';

at-least()

Target the items inside elements that contain $count items or more:

@include at-least($count, $selector) { ... }

at-most()

Target the items inside elements that contain $count items or less:

@include at-most($count, $selector) { ... }

between()

Target the items inside elements that contain a range between $first and $last items:

@include between($first, $last, $selector) { ... }

exactly()

Target the items inside elements that contain exactly $count items:

@include exactly($count, $selector) { ... }

even()

Target the items inside elements that contain an even number of items:

@include even($selector) { ... }

odd()

Target the items inside elements that contain an odd number of items:

@include odd($selector) { ... }

multiple-of()

Target the items inside elements that contain a multiple of $count number of items:

@include multiple-of($selector) { ... }

Example

Sass input:

ul > li {

	// Color the `li` items red when there are 6 items or more
	@include at-least(6) {
		color: red;
	}

	// Color the `li` items blue when there are 4 items or less
	@include at-most(4) {
		color: blue;
	}

	// Add a green background to `li` items when there are between 5 and 8 items
	@include between(5, 8) {
		background-color: green;
	}

	// Add a shadow to `li` items when there are exactly 8 items
	@include exactly(8) {
		box-shadow: 0 1px 3px #000;
	}

	// Add a red outline to `li` items when there is an even number of them
	@include even() {
		outline: solid 2px red;
	}

	// Add a blue outline to `li` items when there is an odd number of them
	@include odd() {
		outline: solid 2px blue;
	}

	// Span every sixth element of a grid when it and its siblings are a multiple of 6
	@include multiple-of(6, '*') {
		&:nth-child(6n + 1) {
			grid-row: span 2;
			grid-column: span 2;
		}
	}
}

Custom selector

The quantity queries mixins default to the current last simple selector for all the items (li in the above example). If you need a different selector or want the quantity query to be selector-agnostic, pass the desired selector to the mixin.

	nav div {
		@include at-least(4, '*') { ... }; // selector agnostic (universal selector)
		@include between(4, 8, 'span') { ... }; // use span instead of div
	}
