# Layout

The following containers are responsive. Change your window's size or select a device preset from your browser's dev tools to see how layouts are affected by available space.

<Tabs>
<Tab title="Flex (default)" icon="⠖">

Items are laid out in a row and wrapped as they overflow the container.
By default, all items in a row assume the same (maximum) height.

```vue-html
<Layout flex>
  <Card title="A" style="width:100px; min-width:100px"></Card>
  <Card title="B" :tags="['funk', 'dunk', 'punk']"></Card>
  <Card title="C" style="width:100px; min-width:100px"></Card>
  <Card title="D"></Card>
</Layout>
```

<div class="preview">
<Layout flex>
  <Card title="A" style="width:100px; min-width:100px"></Card>
  <Card title="B" :tags="['funk', 'dunk', 'punk']"></Card>
  <Card title="C" style="width:100px; min-width:100px"></Card>
  <Card title="D"></Card>
</Layout>
</div>

<Tab title="Grid" icon="ꖛ">

<Layout flex>

```vue-html{1}
<Layout grid :column-width=90>
  <Alert>A</Alert>
  <Alert>B</Alert>
  ...
</Layout>
```

<div class="preview">
<Layout grid :column-width=90>
  <Alert>A</Alert>
  <Alert>B</Alert>
  <Alert>C</Alert>
  <Alert>D</Alert>
  <Alert>E</Alert>
  <Alert>F</Alert>

  <Card title="B"></Card>
  <Card title="C" class="span-2-rows"></Card>
  <Card title="D"></Card>
</Layout>
```

<Layout grid>
  <Card title="A" class="span-2-columns">

    ```vue
    <Card class="span-2-columns"></Card>
    ```

  </Card>
  <Card title="B"></Card>
  <Card title="C" class="span-2-rows">

  <Card title="A"></Card>
  <Card title="B"></Card>
  <Card title="C"></Card>
  <Card title="D"></Card>
  <Card title="E"></Card>

  <Card title="C"></Card>
  <Card title="D"></Card>
  <Card title="E"></Card>
</Layout>
</div>

</Layout>

</Tab>

<Tab title="Columns" icon="𝌆">

Let items flow like words on a printed newspaper, Great for very long lists of buttons or links.

<Layout stack>

```vue-html
<Layout columns :column-width="120">
  <Button icon="bi-star"/>
  <Button icon="bi-star"/>
  <Button icon="bi-star"/>

Normal paragraph. Text flows like in a newspaper. Set the column width in px. Columns will be equally distributed over the width of the container.

  <Card small title="Cards...">...break over columns...</Card>

  <Button icon="bi-star"/>
  <Button icon="bi-star"/>
  <Button icon="bi-star"/>
</Layout>
```

<div class="preview">
<Layout columns :column-width="120">
  <Button icon="bi-star"/>

<Card small title="Cards...">...break over columns...</Card>

---

  <Button icon="bi-star"/>
  <Button icon="bi-star"/>
  <Button icon="bi-star"/>
</Layout>
</div>

</Layout>

</Tab>

</Tabs>

## Common props

### `no-gap`: Remove the gap between items

<Layout flex>

```vue
<script setup>
const noGap = ref(true);
</script>

<template>
  <Toggle v-model="noGap" />

  <Layout flex :no-gap="noGap || undefined">
    <Card title="A" style="width:100px; min-width:100px" />
    <Card title="B" />
    <Card title="C" style="width:100px; min-width:100px" />
    <Card title="D" />
  </Layout>
</template>
```

<div class="preview">
  <Toggle v-model="noGap" /> {{ noGap ? 'no-gap' : '-' }}

---

  <Layout flex :no-gap="noGap || undefined">
    <Card title="A" style="width:100px; min-width:100px" />
    <Card title="B" />
    <Card title="C" style="width:100px; min-width:100px" />
    <Card title="D" />
  </Layout>
</div>

</Layout>

### Add fixed or flexible Spacers

If you add a spacer with attribute `grow`, it will push the other item until the Layout fills the available space. This only works if the parent element itself grows beyond its minimal contents.

<Layout flex>

```vue
<script setup>
const isGrowing = ref(true);
</script>

<template>
  <Toggle v-model="isGrowing" />

  <Layout stack style="height:30em;">
    <Alert>A</Alert>
    <Alert>B</Alert>
    <Spacer :grow="isGrowing || undefined" />
    <Alert>C (footer)</Alert>
  </Layout>
</template>
```

<div class="preview">
<Toggle v-model="isGrowing" /> {{ isGrowing ? 'grow' : '-' }}

---

<Layout stack style="height:30em; background:rgba(155,200,20,.3)">
  <Alert>A</Alert>
  <Alert>B</Alert>
    <Spacer :grow="isGrowing || undefined" />
  <Alert>C (footer)</Alert>
</Layout>
</div>

</Layout>

Multiple spacers will distribute their growth evenly.

Note that you can set the minimum space occupied by the `Spacer` with its `size` prop [(docs)](layout/spacer). Negative values can offset the gap of the `Layout`:

<Layout flex>

```vue
<template>
  <Toggle v-model="isGrowing" />

  <Layout stack style="height:25em;">
    <Alert>A</Alert>
    <Spacer :size="-32" :grow="isGrowing || undefined" />
    <Alert>B1</Alert>
    <Alert>B2</Alert>
    <Spacer :size="-32" :grow="isGrowing || undefined" />
    <Alert>C (footer)</Alert>
  </Layout>
</template>
```

<div class="preview" style="width:0">
<Toggle v-model="isGrowing" />

---

<Layout stack style="height:25em; background:rgba(155,200,20,.3)">
    <Alert>A</Alert>
    <Spacer :size="-32" :grow="isGrowing || undefined" />
    <Alert>B1</Alert>
    <Alert>B2</Alert>
    <Spacer :size="-32" :grow="isGrowing || undefined" />
    <Alert>C (footer)</Alert>
  </Layout>
</div>

</Layout>
