# STWebpageController

The controller you use to report web usage and block restricted webpages.

```
class STWebpageController
```

## Overview

This class provides a convenient way for you to communicate changes in each webpage, such as when the user starts or stops playing media. When a parent or guardian of the user blocks the webpage’s current URL, the webpage controller:

- Automatically occludes the web page’s content
- Updates a KVO-compliant [`urlIsBlocked`](/documentation/ScreenTime/STWebpageController/urlIsBlocked) property

For example, you can observe `urlIsBlocked` and take action when it changes to <doc://com.apple.documentation/documentation/ObjectiveC/YES>, such as pausing media.

> Important: Create a webpage controller for each webpage or tab and add it on top of the webpage’s content.
