# useBreakpoints
Reactive viewport breakpoints.
## Usage
```ts
import { breakpointsTailwind, useBreakpoints } from '@vueuse/core';
const breakpoints = useBreakpoints(breakpointsTailwind);
const smAndLarger = breakpoints.greaterOrEqual('sm'); // sm and larger
const largerThanSm = breakpoints.greater('sm'); // only larger than sm
const lgAndSmaller = breakpoints.smallerOrEqual('lg'); // lg and smaller
const smallerThanLg = breakpoints.smaller('lg'); // only smaller than lg
```
```vue
<script setup lang="ts">
import { useBreakpoints } from '@vueuse/core';
const breakpoints = useBreakpoints({
mobile: 0, // optional
tablet: 640,
laptop: 1024,
desktop: 1280,
});
// Can be 'mobile' or 'tablet' or 'laptop' or 'desktop'
const activeBreakpoint = breakpoints.active();
// true or false
const laptop = breakpoints.between('laptop', 'desktop');
</script>
<template>
<div :class="activeBreakpoint">...</div>
</template>
```
#### Server Side Rendering and Nuxt
If you are using `useBreakpoints` with SSR enabled, then you need to specify which screen size you would like to render on the server and before hydration to avoid an hydration mismatch
```ts
import { breakpointsTailwind, useBreakpoints } from '@vueuse/core';
const breakpoints = useBreakpoints(breakpointsTailwind, {
ssrWidth: 768, // Will enable SSR mode and render like if the screen was 768px wide
});
```
Alternatively you can set this up globally for your app using [`provideSSRWidth`](../useSSRWidth/index.md)
## Presets
- Tailwind: `breakpointsTailwind`
- Bootstrap v5: `breakpointsBootstrapV5`
- Vuetify v2: `breakpointsVuetifyV2` (deprecated: `breakpointsVuetify`)
- Vuetify v3: `breakpointsVuetifyV3`
- Ant Design: `breakpointsAntDesign`
- Quasar v2: `breakpointsQuasar`
- Sematic: `breakpointsSematic`
- Master CSS: `breakpointsMasterCss`
- Prime Flex: `breakpointsPrimeFlex`
- ElementUI / ElementPlus: `breakpointsElement`
_Breakpoint presets are deliberately not auto-imported, as they do not start with `use` to have the scope of VueUse. They have to be explicitly imported:_
```js
import { breakpointsTailwind } from '@vueuse/core';
// and so on
```
## Type Declarations
```ts
export * from './breakpoints';
export type Breakpoints<K extends string = string> = Record<K, MaybeRefOrGetter<number | string>>;
export interface UseBreakpointsOptions extends ConfigurableWindow {
/**
* The query strategy to use for the generated shortcut methods like `.lg`
*
* 'min-width' - .lg will be true when the viewport is greater than or equal to the lg breakpoint (mobile-first)
* 'max-width' - .lg will be true when the viewport is smaller than the xl breakpoint (desktop-first)
*
* @default "min-width"
*/
strategy?: 'min-width' | 'max-width';
ssrWidth?: number;
}
/**
* Reactively viewport breakpoints
*
* @see https://vueuse.org/useBreakpoints
*
* @__NO_SIDE_EFFECTS__
*/
export declare function useBreakpoints<K extends string>(
breakpoints: Breakpoints<K>,
options?: UseBreakpointsOptions,
): Record<K, ComputedRef<boolean>> & {
greaterOrEqual: (k: MaybeRefOrGetter<K>) => ComputedRef<boolean>;
smallerOrEqual: (k: MaybeRefOrGetter<K>) => ComputedRef<boolean>;

current: () => ComputedRef<K[]>;
active(): ComputedRef<'' | K>;
};
export type UseBreakpointsReturn<K extends string = string> = ReturnType<typeof useBreakpoints<K>>;
