### CSS Tip

[](#css-tip)

Adding special CSS, will show the difference between **mandatory** and **dependent mandatory** form fields.

This is only an example:

```
label.dependent.mandatory:after {
	content: '(*)';
	font-size: 9px;
	vertical-align: super;
	color: #FF7777;
}

```

With the CSS above, a form like the following will be created:
