# Frameless Window
A borderless window is a special type of window mode that does not have a shell (including window borders, title bars, toolbars, etc.), containing only the web content. Using a borderless window mode allows you to fully customize the window interface, making your application look consistent across all operating systems. However, since borderless windows do not have a system-provided shell, care must be taken while using them to avoid affecting the user experience.
## Create a Borderless Window
In the `manifest.json` file, set the `frame` property of the `window` object to `false` to enable borderless window mode.
```json
{
"id": "LB5UL2P0Q9FFF",
"version": "1.0.0",
"name": "Hello World",
"logo": "/logo.png",
"keywords": ["keywrod1", "keywrod2"],
"main":
{
"frame": false, // 👈 Borderless mode
"url": "index.html",
"width": 640,
"height": 480
}
}
```
## Draggable Area
You can use the `-webkit-app-region` property in your application to control the draggable area of the application window.
By default, borderless windows are non-draggable. The application needs to specify `-webkit-app-region: drag` in CSS to tell the plugin which areas are draggable (like standard title bars of the operating system). Use `-webkit-app-region: no-drag` within the draggable area to exclude some parts. Please note that currently only rectangular shapes are supported.
To make the entire window draggable, you can add `-webkit-app-region: drag` as the `body` style:
```html
```
Please note that if you make the entire window draggable, you must mark the buttons inside as not draggable, otherwise users will not be able to click on them:
```css
button {
-webkit-app-region: no-drag;
}
```
If you only set the custom title bar to be draggable, you also need to make all the buttons within the title bar non-draggable.
