## Alert

Displays important alert messages.

### Basic usage

Alert components are non-overlay elements in the page that does not disappear automatically.

::: demo Alert provides 4 types of themes defined by `type`, whose default value is `info`.

```html
<template>
  <el-alert
    title="success alert"
    type="success">
  </el-alert>
  <el-alert
    title="info alert"
    type="info">
  </el-alert>
  <el-alert
    title="warning alert"
    type="warning">
  </el-alert>
  <el-alert
    title="error alert"
    type="error">
  </el-alert>
</template>
```
:::

### Customizable close button

Customize the close button as texts or other symbols.

::: demo Alert allows you to configure if it's closable. The close button text and closing callbacks are also customizable. `closable` attribute decides if the component can be closed or not. It accepts `boolean`, and the default is `true`. You can set `close-text` attribute to replace the default cross symbol as the close button. Be careful that `close-text` must be a string. `close` event fires when the component is closed.

```html
<template>
  <el-alert
    title="unclosable alert"
    type="success"
    :closable="false">
  </el-alert>
  <el-alert
    title="customized close-text"
    type="info"
    close-text="Gotcha">
  </el-alert>
  <el-alert
    title="alert with callback"
    type="warning"
    @close="hello">
  </el-alert>
</template>

<script>
  export default {
    methods: {
      hello() {
        alert('Hello World!');
      }
    }
  }
</script>
```

### With icon

Displaying an icon improves readability.

::: demo Setting the `show-icon` attribute displays an icon that corresponds with the current Alert type.

```html
<template>
  <el-alert
    title="success alert"
    type="success"
    show-icon>
  </el-alert>
  <el-alert
    title="info alert"
    type="info"
    show-icon>
  </el-alert>
  <el-alert
    title="warning alert"
    type="warning"
    show-icon>
  </el-alert>
  <el-alert
    title="error alert"
    type="error"
    show-icon>
  </el-alert>
</template>
```
:::

## Centered text

Use the `center` attribute to center the text.

::: demo

```html
<template>
  <el-alert
    title="success alert"
    type="success"
    center
    show-icon>
  </el-alert>
  <el-alert
    title="info alert"
    type="info"
    center
    show-icon>
  </el-alert>
  <el-alert
    title="warning alert"
    type="warning"
    center
    show-icon>
  </el-alert>
  <el-alert
    title="error alert"
    type="error"
    center
    show-icon>
  </el-alert>
</template>
```
:::

### With description

Description includes a message with more detailed information.

::: demo Besides the required `title` attribute, you can add a `description` attribute to help you describe the alert with more details. Description can only store text string, and it will word wrap automatically.

```html
<template>
  <el-alert
    title="with description"
    type="success"
    description="This is a description.">
  </el-alert>
</template>
```
:::

### With icon and description

::: demo At last, this is an example with both icon and description.

```html
<template>
  <el-alert
    title="success alert"
    type="success"
    description="more text description"
    show-icon>
  </el-alert>
  <el-alert
    title="info alert"
    type="info"
    description="more text description"
    show-icon>
  </el-alert>
  <el-alert
    title="warning alert"
    type="warning"
    description="more text description"
    show-icon>
  </el-alert>
  <el-alert
    title="error alert"
    type="error"
    description="more text description"
    show-icon>
  </el-alert>
</template>
```
