Install:

bower install hagrid

npm install hagrid

@import "[path to hagrid]/hagrid";

Use:

// * Initialize a basic grid

.parent {

	@include g;

	// * Initialize a grid with a set of modifiers
	// * Modifiers are applied to all items of one grid
	@include g(full, rev);

	// * Alt. Syntax
	@include grid(full, rev);

}

// * Initialize a grid-item with a set of responsive widths

.item {

	// * The general width is set without a breakpoint-keyword (e.g. md)
	// * Responsive widths are set in the config-map $hagrid-breakpoints
	@include i(1/2, 1/3 md, 1/4 lg);

	// * If you initialize an item without arguments or a general width, it defaults to 100% (mobile first)
	@include i;
	@include i(2/3 md, 3/4 lg);

	// * You can use whatever you want as values
	// * Fractions work great for grids and allow for complex grids without doing math
	// * Passing in false will prevent @i from setting any general width

	// * Recommended
	@include i(1/2, 1/3 md, 1/4 lg);

	//* Possible
	@include i(false, lg 50%);

	// * You can use custom breakpoints in Hagrid. Those should be quoted
	// * Breakpoints pointing at $hagrid-breakpoints should not be quoted
	@include i(2/3 "(min-width: 580px)", 1/3 lg);

	// * Alt. Syntax
	@include item();
}

Note: display: flex is set on each grid-parent, so you have to re-set it on grid-items if you use the fallback-grid and want to use flexbox-properties in grid-items.

Options:

// *  Specify gutters between items. They are used like modifiers or applied to all grids
$hagrid-gutters: (
    default: 1.5rem,
    full: 0,
    narrow: 0.5rem,
    wide: 3rem
);

// * Set common breakpoints used in your project. Can be used in the @bp-mixin (see below)
$hagrid-breakpoints: (
    sm: "(min-width: 35.5em)",
    md: "(min-width: 48em)",
    lg: "(min-width: 64em)",
    xl: "(min-width: 80em)"
);

// * Gutters and modifiers are applied to all items of each grid-container
// * By default, the selector `> *` is used. If you use a consistent selector for grid-items, you can set it here
$hagrid-item-selector: "> *";


// * If you want to add an `inline-block`-grid for older browsers, set this to true
$hagrid-fallback: false;

// * By default, the whitespace issue is fixed the pure-way via letter-spacing / font-family
// * If you want to fix the issue via 0-whitespace HTML, set `$hagrid-fallback-fontfix` to false
$hagrid-fallback-fontfix: true;

// * If you are using the fontfix (recommended), reset your typeface here
$hagrid-fallback-font: sans-serif;

// * Displays warnings about modifiers / mixins that won't work on the fallback
$hagrid-fallback-warnings: false;

// * When set to true, hagrid will extend shared properties among grids and grid-items
// * When set to false (default), the output will be better traceable but slightly larger (gzip will eat this up)
$hagrid-dry-mixins: false;

Modifiers:

// * Modifiers are set on grids
@include g(center, middle, full);

x-axis Alignment:

• right: Align grid-items to the right in partially filled rows.
• center: Center grid-items in partially filled rows.
• space-around: Distribute items in partially filled rows by using variable space around them.
• space-between: Distribute items in partially filled rows by using variable space between them.

y-axis Alignment:

• bottom: Align items to the bottom of the grid.
• middle: Vertically center grid items.

Spacing:

You can provide custom gutters to the grid via the config-variable $hagrid-gutters. Use them as you would use a normal modifier. (e.g. @include g(wide))

Direction:

• rev: Reverted grid on x-axis.
• flip: Reverted grid on y-axis.

Mixins:

• bp: Use breakpoints directly in a class.
• stretch: Assign stretch-mixin to a group of grid-items in a grid to stretch-align their contents.

Example (bp):

 .item {
 		// * Single Breakpoint
 		@include bp(md) {
 			text-align: left;
 		}
 		// * Multiple Breakpoints
 		@include bp(md, lg) {
 			text-align: left;
 		}
 		// * Specific Breakpoints
 		@include bp("(min-width: 568px and max-width: 640px)") {
 			text-align: left;
 		}
 }

Example (stretch):

.stretch {
	@include g;
	> .item {
		@include i;
		@include stretch;
	}
}

Automatic Grid Layouts:

An automatic grid modifier was included until v1.1.0 but then removed because of its inconsistency with the fallback-grid. It will be re-added when the fallback can be safely dropped. Example of automatic grids with pure flexbox:

.grid {
    display: flex;
    flex: 1 1 auto;
}

.grid-item {
     flex: 1 1 0%;
}

.grid-item.example {
    flex: 0 0 auto;
    width: 50%;
}

Browser Support:

• Chrome
• Firefox
• Safari 7+ (Fallback 6+)
• Android 4.4+ (Fallback 2.3+)
• IE 10+ (Fallback 9+ / 8+ with polyfill & -rem)
• Opera 12+

Prefixes:

Hagrid does not generate prefixes (-webkit-,-ms-) as it is designed to be integrated with common SASS workflows in mind (Gulp / Grunt with Autoprefixer). A sample configuration for Autoprefixer is available in the test build-file. Be careful not to set browsers in a way that generates legacy flexbox syntax!
