# Accessibility class
|
|
|
|
The Accessibility class provides methods for inspecting Chromium'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).
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
export declare class Accessibility
|
|
```
|
|
|
|
## Remarks
|
|
|
|
Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might have wildly different output.
|
|
|
|
Blink - Chrome's rendering engine - has a concept of "accessibility tree", which is then translated into different platform-specific APIs. Accessibility namespace gives users access to the Blink Accessibility Tree.
|
|
|
|
Most of the accessibility tree gets filtered out when converting from Blink AX Tree to Platform-specific AX-Tree or by assistive technologies themselves. By default, Puppeteer tries to approximate this filtering, exposing only the "interesting" nodes of the tree.
|
|
|
|
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Accessibility` class.
