# BrowserView
A `BrowserView` can be used to embed additional web content into a
[`BrowserWindow`](browser-window.md). It is like a child window, except that it is positioned
relative to its owning window. It is meant to be an alternative to the
`webview` tag.
## Class: BrowserView
> Create and control views.
Process: [Main](../glossary.md#main-process)
This module cannot be used until the `ready` event of the `app`
module is emitted.
### Example
```javascript
// In the main process.
const { app, BrowserView, BrowserWindow } = require('electron')
app.whenReady().then(() => {
const win = new BrowserWindow({ width: 800, height: 600 })
const view = new BrowserView()
win.setBrowserView(view)
view.setBounds({ x: 0, y: 0, width: 300, height: 300 })
view.webContents.loadURL('https://electronjs.org')
})
```
### `new BrowserView([options])` _Experimental_
* `options` Object (optional)
* `webPreferences` Object (optional) - See [BrowserWindow](browser-window.md).
### Instance Properties
Objects created with `new BrowserView` have the following properties:
#### `view.webContents` _Experimental_
A [`WebContents`](web-contents.md) object owned by this view.
### Instance Methods
Objects created with `new BrowserView` have the following instance methods:
#### `view.setAutoResize(options)` _Experimental_
* `options` Object
* `width` boolean (optional) - If `true`, the view's width will grow and shrink together
with the window. `false` by default.
* `height` boolean (optional) - If `true`, the view's height will grow and shrink
together with the window. `false` by default.
* `horizontal` boolean (optional) - If `true`, the view's x position and width will grow
and shrink proportionally with the window. `false` by default.
* `vertical` boolean (optional) - If `true`, the view's y position and height will grow
and shrink proportionally with the window. `false` by default.
#### `view.setBounds(bounds)` _Experimental_
* `bounds` [Rectangle](structures/rectangle.md)
Resizes and moves the view to the supplied bounds relative to the window.
#### `view.getBounds()` _Experimental_
Returns [`Rectangle`](structures/rectangle.md)
The `bounds` of this BrowserView instance as `Object`.
#### `view.setBackgroundColor(color)` _Experimental_
* `color` string - Color in Hex, RGB, ARGB, HSL, HSLA or named CSS color format. The alpha channel is
optional for the hex type.
Examples of valid `color` values:
* Hex
* #fff (RGB)
* #ffff (ARGB)
* #ffffff (RRGGBB)
* #ffffffff (AARRGGBB)
* RGB
* rgb\((\[\d]+),\s*(\[\d]+),\s*(\[\d]+)\)
* e.g. rgb(255, 255, 255)
* RGBA
* rgba\((\[\d]+),\s*(\[\d]+),\s*(\[\d]+),\s*(\[\d.]+)\)
* e.g. rgba(255, 255, 255, 1.0)
* HSL
* hsl\((-?\[\d.]+),\s*(\[\d.]+)%,\s*(\[\d.]+)%\)
* e.g. hsl(200, 20%, 50%)
* HSLA
* hsla\((-?\[\d.]+),\s*(\[\d.]+)%,\s*(\[\d.]+)%,\s*(\[\d.]+)\)
* e.g. hsla(200, 20%, 50%, 0.5)
* Color name
* Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
* Similar to CSS Color Module Level 3 keywords, but case-sensitive.
* e.g. `blueviolet` or `red`
**Note:** Hex format with alpha takes `AARRGGBB` or `ARGB`, _not_ `RRGGBBA` or `RGA`.
