# Form Layout Styling

## <a id="style-properties"></a>Style Properties

The following style properties can be used in CSS stylesheets to customize the appearance of this component.

To apply values to these properties globally in your application UI, place them in a CSS block using the `html {…​}` selector. See [Component Style Properties](https://vaadin.com/docs/next/styling/styling-components.md#component-style-properties) for more information on style properties.

| Feature                 | CSS Property                          | Flow API           |
| ----------------------- | ------------------------------------- | ------------------ |
| Spacing between columns | `--vaadin-form-layout-column-spacing` | `setColumnSpacing` |
| Spacing between rows    | `--vaadin-form-layout-row-spacing`    | `setRowSpacing`    |

### <a id="side-labels"></a>Side Labels

The following style properties and Flow methods can be used to customize the width of labels and the spacing between them and the fields in label-aside mode:

| Feature                              | CSS Property                         | Flow API          |
| ------------------------------------ | ------------------------------------ | ----------------- |
| Side label width                     | `--vaadin-form-layout-label-width`   | `setLabelWidth`   |
| Spacing between side label and field | `--vaadin-form-layout-label-spacing` | `setLabelSpacing` |

**Flow** — `FormLayoutLabelStyling.java`

```java
FormLayout formLayout = new FormLayout();
formLayout.setAutoResponsive(true);
formLayout.setLabelsAside(true);
formLayout.addFormItem(new TextField(), "First name");
formLayout.addFormItem(new TextField(), "Last name");
formLayout.addFormItem(new EmailField(), "Email address");

formLayout.setLabelWidth("10em");
formLayout.setLabelSpacing("2em");
```

**React** — `form-layout-label-styling.tsx`

```tsx
return (
  <FormLayout
    autoResponsive
    labelsAside
    style={{
      '--vaadin-form-layout-label-width': '10em',
      '--vaadin-form-layout-label-spacing': '2em',
    }}
  >
    <FormItem>
      <label slot="label">First name</label>
      <TextField />
    </FormItem>
    <FormItem>
      <label slot="label">Last name</label>
      <TextField />
    </FormItem>
    <FormItem>
      <label slot="label">Email address</label>
      <EmailField />
    </FormItem>
  </FormLayout>
);
```

**Lit** — `form-layout-label-styling.ts`

```typescript
return html`
  <vaadin-form-layout
    auto-responsive
    labels-aside
    style="
      --vaadin-form-layout-label-width: 10em;
      --vaadin-form-layout-label-spacing: 2em;
    "
  >
    <vaadin-form-item>
      <label slot="label">First name</label>
      <vaadin-text-field></vaadin-text-field>
    </vaadin-form-item>
    <vaadin-form-item>
      <label slot="label">Last name</label>
      <vaadin-text-field></vaadin-text-field>
    </vaadin-form-item>
    <vaadin-form-item>
      <label slot="label">Email address</label>

## <a id="css-selectors"></a>CSS Selectors

The following CSS selectors can be used in stylesheets to target the various parts and states of the component. See the [Styling documentation](https://vaadin.com/docs/next/styling.md) for more details on how to style components.

> **Important: Not for Shadow DOM**
>
> These selectors should be used in `styles.css` or another stylesheet loaded with the `@StyleSheet` annotation or the `@import` CSS rule. **They do not work in the shadow DOM of Vaadin components**, such as in stylesheets in the `components` sub-folder or loaded with the `@CssImport` annotation’s `themeFor` property.
