Gutters

Markdown ChatGPT Claude

Gutters are the padding between your columns, used to responsively space and align content in the CoreUI for Vue.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-5:

vue

<template>
  <CContainer class="px-5">
    <CRow :xs="{ gutterX: 6 }">
      <CCol>
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

<script setup>
import { CContainer, CRow, CCol } from '@coreui/vue'
</script>

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

vue

<template>
  <CContainer class="overflow-hidden">
    <CRow :xs="{ gutterX: 6 }">
      <CCol>
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

<script setup>
import { CContainer, CRow, CCol } from '@coreui/vue'
</script>

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:

vue

<template>
  <CContainer class="overflow-hidden">
    <CRow :xs="{ gutterY: 6 }">
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

<script setup>
import { CContainer, CRow, CCol } from '@coreui/vue'
</script>

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.

vue

<template>
  <CContainer>
    <CRow :xs="{ gutter: 3 }">
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-4 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

<script setup>
import { CContainer, CRow, CCol } from '@coreui/vue'
</script>

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.

vue

<template>
  <CContainer>
    <CRow :xs="{ cols: 2, gutter: 3 }" :lg="{ cols: 5, gutter: 4 }">
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
      <CCol>
        <div class="p-4 border bg-light">Row column</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

<script setup>
import { CContainer, CRow, CCol } from '@coreui/vue'
</script>

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).

vue

<template>
  <div class="docs-example-row">
    <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>
  </div>
</template>

<script setup>
import { CRow, CCol } from '@coreui/vue'
</script>

Change the gutters

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

$grid-gutter-x: 1.5rem;
$gutters: (
  0: 0,
  1: $spacer * .25,
  2: $spacer * .375,
  3: $spacer * .5,
  4: $spacer * .75,
  5: $spacer,
  6: $spacer * 1.25,
  7: $spacer * 1.5,
  8: $spacer * 1.75,
  9: $spacer * 2,
  10: $spacer * 2.25,
  11: $spacer * 2.5,
  12: $spacer * 3,
);
