This keeps your app safe from the embedded content.

 ## Synopsis
 
 To embed a web page in your app, add the webview tag to your app's embedder page (this is the app page that will display the guest content). In its simplest form, the webview tag includes the src of the web page and css styles that control the appearance of the webview container:
 
 ```html
-<webview id="foo" src="http://www.google.com/" style="width:640px; height:480px"></webview>
+<webview id="foo" src="http://www.google.com/" style="width:640px; height:480px">
+</webview>
 ```

 ### Node.js support in webview
 
 To enable Node.js support in WebView, add the `allownw` attribute to the webview tag. Then Node.js will be turned on, no matter it loads local file or remote site. Use this feature with caution because webview is normally supposed to load untrusted contents.
 
 ### executeScript in main world
 
-The [executeScript function in Chrome](https://developer.chrome.com/apps/tags/webview#method-executeScript) lets you inject JS code into webview, but in a isolated world. To access JS objects in the target DOM context, you can inject code into the main world context instead. Simply adding `{mainWorld: true}` to `InjectDetails` typed parameter of the function.
