### `guestinstance`
```html
<webview src="https://www.github.com/" guestinstance="3"></webview>
```
A value that links the webview to a specific webContents. When a webview
first loads a new webContents is created and this attribute is set to its
instance identifier. Setting this attribute on a new or existing webview
connects it to the existing webContents that currently renders in a different
webview.
The existing webview will see the `destroy` event and will then create a new
webContents when a new url is loaded.
### `disableguestresize`
```html
<webview src="https://www.github.com/" disableguestresize></webview>
```
When this attribute is present the `webview` contents will be prevented from
resizing when the `webview` element itself is resized.
This can be used in combination with
[`webContents.setSize`](web-contents.md#contentssetsizeoptions) to manually
resize the webview contents in reaction to a window size change. This can
make resizing faster compared to relying on the webview element bounds to
automatically resize the contents.
```javascript
const {webContents} = require('electron')
// We assume that `win` points to a `BrowserWindow` instance containing a
// `<webview>` with `disableguestresize`.
win.on('resize', () => {
const [width, height] = win.getContentSize()
for (let wc of webContents.getAllWebContents()) {
// Check if `wc` belongs to a webview in the `win` window.
if (wc.hostWebContents &&
wc.hostWebContents.id === win.webContents.id) {
wc.setSize({
normal: {
width: width,
height: height
}
})
}
}
})
```
