 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).
 
+**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.

+ElementHandle prevents the DOM element from being garbage-collected unless the handle is [disposed](./puppeteer.jshandle.dispose.md). ElementHandles are auto-disposed when their origin frame gets navigated.

+ElementHandle instances can be used as arguments in [Page.$eval()](./puppeteer.page._eval.md) and [Page.evaluate()](./puppeteer.page.evaluate.md) methods.
+
+If you're using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a `<select>` element, you can type it as `ElementHandle<HTMLSelectElement>` and you get some nicer type checks.
