## Input help
Use an input helper to display additional information about a form element. The text label will appear once a user hovers over the helper. To add an input helper, use the `.form-help` class.
```html
?
```
Look at the example below to see how the input help works:
```html example centered height="25rem" columns={1}
```
## Required field
Use the `.required` class to indicate that a field is required. It will add a red asterisk to the label.
```html
```
Look at the example below to see how the required field works:
```html example centered columns={1}
```
## Form hint
Use a form hint to provide users with additional information about a form element. The text will appear below the input field. To add a form hint, use the `.form-hint` class.
```html
We'll never share your email with anyone else.
```
Look at the example below to see how the form hint works:
```html example centered columns={1}
We'll never share your email with anyone else.
```
## Additional info inside label
Use the `.form-label-description` class to add additional information to the label. The text will appear next to the label. You can use it to add for example a character counter.
```html
```
This example shows how to use the additional info inside the label:
```html example centered columns={1} height="15rem"
