What is transition:fade used for?
In Svelte, transition:fade is used to smoothly fade elements in or out when they are added or removed from the DOM. It is a built-in transition that animates an element's opacity from 0 to 1 (fade in) or from 1 to 0 (fade out).
Example: Fade In and Out
You can pass options to fade such as duration (milliseconds) or delay before the transition starts.
Example: Fade with Options
Best practices and notes:
transition:fadeonly works on elements entering or leaving the DOM.Combine with
{#if}blocks for conditional rendering with smooth fades.Supports options like
duration,delay, andeasing.It is one of several built-in transitions Svelte provides, including
slide,scale, anddraw.
