Responsive grid

react-grid-system provides a responsive grid similar to Bootstrap (see: http://getbootstrap.com/css/#grid), except here, it's React components only, and no CSS is used at all.

Three components are provided for creating responsive grids: Container, Row, and Col.

An example on how to use these:

<Container>
  <Row>
    <Col sm={4}>
      One of three columns
    </Col>
    <Col sm={4}>
      One of three columns
    </Col>
    <Col sm={4}>
      One of three columns
    </Col>
  </Row>
</Container>

Responsive utilities

Next to the grid, two components are provided for showing or hiding content: Visible and Hidden. The main difference between these two components and the similar CSS classes provided by Bootstrap is that these two components do not render the content at all when it should be hidden, instead of just hiding it with CSS.

Some examples on how to use these components:

<p>
  <span>Your current screen class is </span>
  <Visible xs><strong>xs</strong></Visible>
  <Visible sm><strong>sm</strong></Visible>
  <Visible md><strong>md</strong></Visible>
  <Visible lg><strong>lg</strong></Visible>
  <Visible xl><strong>xl</strong></Visible>
  <span>.</span>
</p>

<Visible xs sm>
  <p>Paragraph visible on extra small and small.</p>
</Visible>
<Hidden xs sm>
  <p>Paragraph hidden on extra small and small.</p>
</Hidden>
<Visible md lg>
  <p>Paragraph visible on medium and large.</p>
</Visible>
<Hidden md lg>
  <p>Paragraph hidden on medium and large.</p>
</Hidden>

Next to that, the ScreenClassRender component is provided, for rendering a component differently based on the screen class. An example on how to use this:

const styleFunction = (screenClass) => {
  if (screenClass === 'xl') return { fontSize: '60px' };
  if (screenClass === 'lg') return { fontSize: '40px' };
  if (screenClass === 'md') return { fontSize: '30px' };
  if (screenClass === 'sm') return { fontSize: '20px' };
  return { fontSize: '10px' };
};

<ScreenClassRender style={styleFunction}><p>Some text which font size depends on the screen class.</p></ScreenClassRender>

Finally, a ClearFix component can be used for resetting a row. This is sometimes needed when not all columns have the same height. For example:

<Row>
  <Col xs={6} sm={3}>
    xs=6 sm=3<br />
    This column has a lot more height, so a clearfix is needed for screenclass xs.
  </Col>
  <Col xs={6} sm={3}>xs=6 sm=3</Col>

  <ClearFix xs />

  <Col xs={6} sm={3}>xs=6 sm=3</Col>
  <Col xs={6} sm={3}>xs=6 sm=3</Col>
</Row>

Context types

The following child context types can be provided to the grid components, to alter their responsive behavior:

Context Type	Default Value	Description
breakpoints	[576, 768, 992, 1200]	The breakpoints (minimum width) of devices in screen class sm, md, lg, and xl. The default values are based on the Bootstrap 4 breakpoints.
containerWidths	[540, 750, 960, 1140]	The container widths in pixels of devices in screen class sm, md, lg, and xl. The default values are based on the Bootstrap 4 container widths.
gutterWidth	30	The gutter width in pixels. A gutter width of 30 means 15px on each side of a column. The default value is based on the Bootstrap 4 gutter width.
serverSideScreenClass	xl	The screen class used when the view port cannot be determined using window. This is useful for server-side rendering (SSR) based on the user agent. See also the example application below.
phone	false	deprecated When set to true, a server-side screen class of xs will be used.
tablet	false	deprecated When set to true, a server-side screen class of md will be used.
