```dts function blur( node: Element, { delay, duration, easing, amount, opacity }?: BlurParams | undefined ): TransitionConfig; ```

## crossfade The `crossfade` function creates a pair of [transitions](/docs/svelte/transition) called `send` and `receive`. When an element is 'sent', it looks for a corresponding element being 'received', and generates a transition that transforms the element to its counterpart's position and fades it out. When an element is 'received', the reverse happens. If there is no counterpart, the `fallback` transition is used.

```dts function crossfade({ fallback, ...defaults }: CrossfadeParams & { fallback?: ( node: Element, params: CrossfadeParams, intro: boolean ) => TransitionConfig; }): [ ( node: any, params: CrossfadeParams & { key: any; } ) => () => TransitionConfig, ( node: any, params: CrossfadeParams & { key: any; } ) => () => TransitionConfig ]; ```

## draw Animates the stroke of an SVG element, like a snake in a tube. `in` transitions begin with the path invisible and draw the path to the screen over time. `out` transitions start in a visible state and gradually erase the path. `draw` only works with elements that have a `getTotalLength` method, like `` and ``.

```dts function draw( node: SVGElement & { getTotalLength(): number; }, { delay, speed, duration, easing }?: DrawParams | undefined ): TransitionConfig; ```

## fade Animates the opacity of an element from 0 to the current opacity for `in` transitions and from the current opacity to 0 for `out` transitions.

```dts function fade( node: Element, { delay, duration, easing }?: FadeParams | undefined ): TransitionConfig; ```

## fly Animates the x and y positions and the opacity of an element. `in` transitions animate from the provided values, passed as parameters to the element's default values. `out` transitions animate from the element's default values to the provided values.

```dts function fly( node: Element, { delay, duration, easing, x, y, opacity }?: FlyParams | undefined ): TransitionConfig; ```

## scale Animates the opacity and scale of an element. `in` transitions animate from the provided values, passed as parameters, to an element's current (default) values. `out` transitions animate from an element's default values to the provided values.

```dts function scale( node: Element, { delay, duration, easing, start, opacity }?: ScaleParams | undefined ): TransitionConfig; ```

## slide Slides an element in and out.

```dts function slide( node: Element, { delay, duration, easing, axis }?: SlideParams | undefined ): TransitionConfig; ```
