+# useDir
+
+Reactive [dir](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/dir) of the element's text.
+
+## Basic Usage
+
+```ts
+import { useDir } from '@vueuse/core'
+
+const dir = useDir() // Ref<'ltr' | 'rtl' | 'auto'>
+
+```
+By default, which enables `rlt` direction when dir `rtl` is applied to the `html` tag, for example:
+
+```html
+<!--ltr-->
+<html> ... </html>
+
+<!--rtl-->
+<html dir="rtl"> ... </html>
+```
+
+## Config
+
+```ts
+import { useDir } from '@vueuse/core'
+
+const mode = useDir({
+  selector: 'body'
+}) // Ref<'ltr' | 'rtl' | 'auto'>
+```
