 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 `<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.
