Grid

The Stacks grid system is a flexible, scaffolding system for product layouts. It’s an extensive system that provides fixed cell widths, gutter spacing, and flex atomic classes.

Basic grid

Section titled Basic grid

A grid is initiated with the .grid class. By default, display: flex; starts a non-wrapping row. To convert it to a column, apply the .fd-column helper class.

<div class="grid">
    <div class="grid--cell">…</div>
    <div class="grid--cell">…</div>
</div>
<div class="grid fd-column">
    <div class="grid--cell">…</div>
    <div class="grid--cell">…</div>
</div>

.grid--cell

Fluid cells

Section titled Fluid cells

By default all child elements of a grid have a default value of flex: 1 0 auto;. This means that by default all cells will only be as wide as their content. If you would like a cell or all the cells to fill the remaining space, apply the .fl1 to the cell, or .grid__fl1 to the parent to apply to all children.

Fixed cells

Section titled Fixed cells

You can either fix the width of an individual element or fix the width of all child elements within a parent container by setting the width on the parent. The cell widths are based on a 12-column grid system.

Nested grids

Section titled Nested grids

Grids can be nested within each other. This allows you to create unique, custom layouts without needing to create new, custom code or override existing styles.

Note: Nested grids with gutter spacing will conflict with each other. If you are nesting a grid with gutter spacing into a grid that also has gutter spacing, the child's parent wrapper margins will be overwritten by the parent. To have the child grid gutter spacing honored, you must place the child grid within a .grid--cell wrapper first. This allows the parent and child grid gutter spacing to act correctly without interfering with each other.

Gutters

Section titled Gutters

Sometimes gutters are desired between cells. To do so apply the appropriate class to the parent wrapper. The gutter applies a margin to all sides. The sizes available are the same as the spacing units.

Gutter classes

Section titled Gutter classes

Class	Output
`.gs2`	2px
`.gs4`	4px
`.gs6`	6px
`.gs8`	8px
`.gs12`	12px
`.gs16`	16px
`.gs24`	24px
`.gs32`	32px
`.gs48`	48px
`.gs64`	64px
`.gsx`	Applies margins only to left and right
`.gsy`	Applies margins only to top and bottom

`.fl0`	Sets flex grow and shrink to 0, flex-basis to auto.
`.fl1`	Sets flex grow and shrink to 1, flex-basis to auto.
`.fl2`	Sets flex grow and shrink to 2, flex-basis to auto.
`.fl3`	Sets flex grow and shrink to 3, flex-basis to auto.
`.fl4`	Sets flex grow and shrink to 4, flex-basis to auto.
`.fl5`	Sets flex grow and shrink to 5, flex-basis to auto.
`.fl-shrink0`	Sets flex shrink value to 0, which means it won’t shrink relative to available space and sibling elements.
`.fl-shrink1`	Sets flex shrink value to 1. This means it will shrink relative to other sibling elements by a factor of 1.
`.fl-shrink2`	Sets flex shrink value to 2. This means it will shrink relative to other sibling elements by a factor of 2.
`.fl-shrink3`	Sets flex shrink value to 3. This means it will shrink relative to other sibling elements by a factor of 3.
`.fl-shrink4`	Sets flex shrink value to 4. This means it will shrink relative to other sibling elements by a factor of 4.

`.fl-none`	This is equivalent to flex: 0 0 auto. It sizes the item according to its width/height properties, but makes it fully inflexible.
`.fl-equal`	Sets flex grow value to 1, flex shrink to 1, and flex basis to 0, allowing for equal spacing of each child.

`.jc-space-around`	Equally distributes the remaining space around child elements. Note that this doesn’t mean the spaces are visually equal, but that the same space unit is applied to both sides of a child element. The first item would have one unit of space against the container edge, but the next item would have two units of space between itself and the first item.
`.jc-space-between`	Evenly distributes the space between child elements along a parent’s main axis with the first item starting on the start line and the last item on the end line.
