# Format payment page

To format the payment page using the style attributes:

{% stepper %}
{% step %}
Add the `ClearentSDK.init()` method.

{% code overflow="wrap" lineNumbers="true" %}

```js
<script type="text/javascript">
    ClearentSDK.init({
        "baseUrl": "https://gateway-sb.clearent.net",
        "pk": "YOUR PUBLIC KEY GOES HERE",
        "styles": ".form-control{color: blue;}.form-control:focus{color: purple;}"
    });
</script>
```

{% endcode %}

The payment form displays the blue text for input fields, and the text changes to purple when the field is selected for input
