Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in the browser.
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Page` class.
## Example 1
This example creates a page, navigates it to a URL, and then saves a screenshot:
The Page class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [PageEvent](./puppeteer.pageevent.md) enum.
| accessibility | <code>readonly</code> | [Accessibility](./puppeteer.accessibility.md) | The Accessibility class provides methods for inspecting the browser's accessibility tree. The accessibility tree is used by assistive technology such as [screen readers](https://en.wikipedia.org/wiki/Screen_reader) or [switches](https://en.wikipedia.org/wiki/Switch_access). |
| coverage | <code>readonly</code> | [Coverage](./puppeteer.coverage.md) | The Coverage class provides methods to gather information about parts of JavaScript and CSS that were used by the page. |
| keyboard | <code>readonly</code> | [Keyboard](./puppeteer.keyboard.md) | Keyboard provides an api for managing a virtual keyboard. The high level api is [Keyboard.type()](./puppeteer.keyboard.type.md), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page. |
| mouse | <code>readonly</code> | [Mouse](./puppeteer.mouse.md) | The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport. |
| touchscreen | <code>readonly</code> | [Touchscreen](./puppeteer.touchscreen.md) | The Touchscreen class exposes touchscreen events. |
| tracing | <code>readonly</code> | [Tracing](./puppeteer.tracing.md) | The Tracing class exposes the tracing audit interface. |
