# Frameless Applications

Wails supports application that have no frames. This can be achieved by using the [frameless](../reference/options.mdx#frameless) field in [Application Options](../reference/options.mdx#application-options).

Wails offers a simple solution for dragging the window: Any HTML element that has the CSS style `--wails-draggable:drag` will act as a "drag handle". This property applies to all child elements. If you need to indicate that a nested element should not drag, then use the attribute '--wails-draggable:no-drag' on that element.


```html
<html>
  <head>
    <link rel="stylesheet" href="/main.css" />
  </head>

  <body style="--wails-draggable:drag">
    <div id="logo"></div>
    <div id="input" style="--wails-draggable:no-drag">
      <input id="name" type="text" />
      <button onclick="greet()">Greet</button>
    </div>
    <div id="result"></div>

    <script src="/main.js"></script>
  </body>
</html>
```

For some projects, using a CSS variable may not be possible due to dynamic styling. In this case, you can use the `CSSDragProperty` and `CSSDragValue` application options to define a property and value that will be used to indicate draggable regions:

```go title=main.go
package main

import (
    "embed"

    "github.com/wailsapp/wails/v2"
    "github.com/wailsapp/wails/v2/pkg/options"
)

//go:embed frontend/dist
var assets embed.FS

func main() {
    // Create an instance of the app structure
    app := NewApp()

    // Create application with options
    err := wails.Run(&options.App{
        Title:           "alwaysontop",
        Width:           1024,
        Height:          768,
        Assets:          assets,
        Frameless:       true,
        CSSDragProperty: "widows",
        CSSDragValue:    "1",
        Bind: []interface{}{
            app,
        },
    })

    if err != nil {
        println("Error:", err)
    }
}
```

```html title=index.html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8"/>
    <meta content="width=device-width, initial-scale=1.0" name="viewport"/>
    <title>alwaysontop</title>
</head>
<body style="widows: 1">
<div id="app"></div>
<script src="./src/main.js" type="module"></script>
</body>
</html>

```

:::info Fullscreen
  If you allow your application to go fullscreen, this drag functionality will be disabled.
