Gutters

Gutters are the padding between your columns, used to responsively space and align content in the CoreUI for React.js grid system.

How they work#

• Gutters are the gaps between column content, created by horizontal padding. We set padding-right and padding-left on each column, and use negative margin to offset that at the start and end of each row to align content.

• Gutters start at 1.5rem (24px) wide. This allows us to match our grid to the padding and margin spacers scale.

• Gutters can be responsively adjusted. Use breakpoint-specific gutter props to modify horizontal gutters, vertical gutters, and all gutters.

Horizontal gutters#

{breakpoint}={{ gutterX: * }} props can be used to control the horizontal gutter widths. The <CContainer> or <CContainer fluid> parent may need to be adjusted if larger gutters are used too to avoid unwanted overflow, using a matching padding utility. For example, in the following example we've increased the padding with .px-4:

<CContainer className="px-4">
  <CRow xs={{ gutterX: 5 }}>
    <CCol>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol>
      <div className="p-3">Custom column padding</div>
    </CCol>
  </CRow>
</CContainer>

An alternative solution is to add a wrapper around the <CRow> with the .overflow-hidden class:

<CContainer className="overflow-hidden">
  <CRow xs={{ gutterX: 5 }}>
    <CCol>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol>
      <div className="p-3">Custom column padding</div>
    </CCol>
  </CRow>
</CContainer>

Vertical gutters#

{breakpoint}={{ gutterY: * }} props can be used to control the vertical gutter widths. Like the horizontal gutters, the vertical gutters can cause some overflow below the <CRow> at the end of a page. If this occurs, you add a wrapper around <CRow> with the .overflow-hidden class:

<CContainer className="overflow-hidden">
  <CRow xs={{ gutterY: 5 }}>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
  </CRow>
</CContainer>

Horizontal & vertical gutters#

{breakpoint}={{ gutter: * }} props can be used to control the horizontal gutter widths, for the following example we use a smaller gutter width, so there won't be a need to add the .overflow-hidden wrapper class.

<CContainer>
  <CRow xs={{ gutter: 2 }}>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
    <CCol xs={{ span: 6 }}>
      <div className="p-3">Custom column padding</div>
    </CCol>
  </CRow>
</CContainer>

Row columns gutters#

Gutter props can also be added to row columns. In the following example, we use responsive row columns and responsive gutter props.

<CContainer>
  <CRow xs={{ cols:2, gutter: 2 }} lg={{ cols: 5, gutter: 3}}>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
    <CCol>
      <div className="p-3">Row column</div>
    </CCol>
  </CRow>
</CContainer>

No gutters#

The gutters between columns in our predefined grid props can be removed with {breakpoint}={{ gutter: 0 }}. This removes the negative margins from <CRow> and the horizontal padding from all immediate children columns.

Need an edge-to-edge design? Drop the parent <CContainer> or <CContainer fluid>.

In practice, here's how it looks. Note you can continue to use this with all other predefined grid props (including column widths, responsive tiers, reorders, and more).

<CRow xs={{ gutter: 0 }}>
  <CCol sm={6} md={8}>.col-sm-6 .col-md-8</CCol>
  <CCol xs={6} md={4}>.col-6 .col-md-4</CCol>
</CRow>

Change the gutters#

Classes are built from the $gutters Sass map which is inherited from the $spacers Sass map.

$grid-gutter-width: 1.5rem;
$gutters: (
  0: 0,
  1: $spacer * .25,
  2: $spacer * .5,
  3: $spacer,
  4: $spacer * 1.5,
  5: $spacer * 3,
);
