# Gutters

> 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](https://coreui.io/docs/utilities/spacing) 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`:

```html
<template>
  <CContainer class="px-4">
    <CRow :xs="{ gutterX: 5 }">
      <CCol>
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol>
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

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

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

```html
<template>
  <CContainer class="overflow-hidden">
    <CRow :xs="{ gutterX: 5 }">
      <CCol>
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol>
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

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

## 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:

```html
<template>
  <CContainer class="overflow-hidden">
    <CRow :xs="{ gutterY: 5 }">
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

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

## 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.

```html
<template>
  <CContainer>
    <CRow :xs="{ gutter: 2 }">
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
      <CCol :xs="{ span: 6 }">
        <div class="p-3 border bg-light">Custom column padding</div>
      </CCol>
    </CRow>
  </CContainer>
</template>

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

## Row columns gutters

Gutter props can also be added to [row columns](../layout/grid#row-columns). In the following example, we use responsive row columns and responsive gutter props.

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

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

## No gutters

The gutters between columns in our predefined grid props can be removed with `:{breakpoint}="{ gutter: 0 }"`. This removes the negative `margin`s 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).

```html
<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>
```
  
</Example>
