Transitions can use custom functions. If the returned object has a `css` function, Svelte will create a CSS animation that plays on the element.
The `t` argument passed to `css` is a value between `0` and `1` after the `easing` function has been applied. *In* transitions run from `0` to `1`, *out* transitions run from `1` to `0` —in other words `1` is the element's natural state, as though no transition had been applied. The `u` argument is equal to `1 - t`.

The `<svelte:element>` element lets you render an element of a dynamically specified type. This is useful for example when displaying rich text content from a CMS. Any properties and event listeners present will be applied to the element.
The only supported binding is `bind:this`, since the element typespecific bindings that Svelte does at build time (e.g. `bind:value` for input elements) do not work with a dynamic tag type.
