SUIT CSS components-grid

Build Status

A CSS grid component. The grid makes use of flexbox and box-sizing to provide features that float-based layouts cannot.

N.B. This component relies on particular dimensions being applied to cells in the grid via other classes. For example, suitcss-utils-size.

  • Grid--alignMiddle: middle-align all child cells
  • Grid--alignBottom: bottom-align all child cells
  • Grid--fill: evenly distribute space amongst all child cells
  • Grid--fit: fit cells to their content
  • Grid--equalHeight: all child cells match height of the tallest

Use

A simple grid is easy to create. A grid container can have any number of child cells. When used with Grid--fill space is evenly distributed without need for sizing utilities.

Note Elements that are direct descendants of Grid will be flex items. It's recommended to use an element that can easily have classes attached later if needed, such as u-sizeFill or u-flexJustifyCenter

<div class="Grid Grid--fill Grid--withGutter">
  <div><!-- cell content --></div>
  <div><!-- cell content --></div>
  <div><!-- cell content --></div>
  <div><!-- cell content --></div>
</div>

For more granular control over layout make use of modifiers and sizing utilities.

<div class="Grid [Grid--alignCenter|Grid--alignRight|Grid--alignMiddle|Grid--alignBottom|Grid--fill|Grid--fit|Grid--equalHeight]">
  <div class="u-size1of2 u-lg-size6of12"></div>
  <div class="u-size1of2 u-lg-size4of12"></div>
  <div class="u-size1of3 u-lg-size2of12"></div>
  <div class="u-size1of3"></div>
</div>

Fit cells to their content and allow others to fill the remaining space.

<div class="Grid">
  <div class="u-sizeFit">Fit to content</div>
  <div class="u-sizeFill">Take up remaining space</div>
</div>

Widths and offsets

Cell widths and offsets can be controlled using the responsive sizing utilities and responsive offset utilities, respectively.

One limitation of creating grid gutters in the manner shown above is that it prevents any offset utilities applied directly to the Grid component from functioning as expected.

GOOD:

<div class="Grid Grid--withGutter">
  <div class="u-size1of2 u-before1of4 u-after1of4">
    {{>partial}}
  </div>
</div>

BAD:

<div class="Grid Grid--withGutter u-before1of4 u-after1of4">
  <div>
    {{>partial}}
  </div>
</div>

You can nest grids in any context, including one that uses dimension or offset utilities, but keep in mind that the dimensions will be relative to the grid's width, and not the width of the whole application.

<div class="u-before1of4 u-after1of4">
  <div class="Grid Grid--withGutter">
    <div class="u-size1of2"> <!-- 50% of the width of the Grid -->
      {{>partial}}
    </div>
  </div>
</div>
