Svelte provides several built-in transitions such as fade, slide, scale, and draw. You can customize these transitions by passing options like duration, delay, and easing to control their behavior.
You apply a transition to an element using the transition: directive followed by the transition function and an optional options object.
duration– time in milliseconds the transition lasts.delay– time in milliseconds to wait before starting the transition.easing– a function controlling the rate of change during the transition (e.g.,cubicIn,cubicOut).css– for some transitions likedraw, you can provide a custom CSS function to override default behavior.
You can combine transitions or apply different options to different elements to achieve more complex animations.
Always wrap transitions around elements that are conditionally rendered (using
{#if}blocks).Adjust
duration,delay, andeasingto match the desired visual effect.Combine multiple transitions for richer animations.
Use built-in transitions as a base and customize options instead of creating from scratch unless needed.
