> [`WebContentsView`](web-contents-view.md) class.
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
<!--
```YAML history
deprecated:
- pr-url: https://github.com/electron/electron/pull/35658
breaking-changes-header: deprecated-browserview
```
-->
> Create and control views.
> **Note**
> The `BrowserView` class is deprecated, and replaced by the new
> [`WebContentsView`](web-contents-view.md) class.
Process: [Main](../glossary.md#main-process)
This module cannot be used until the `ready` event of the `app`
module is emitted.
### Example
```js
// 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')
})
```

* `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_ `RRGGBBAA` or `RGB`.
