Resize Observer
[component-header:sl-resize-observer]
The Resize Observer component offers a thin, declarative interface to the ResizeObserver API
.
The resize observer will report changes to the dimensions of the elements it wraps through the sl-resize
event. When emitted, a collection of ResizeObserverEntry
objects will be attached to event.detail
that contains the target element and information about its dimensions.
<div class="resize-observer-overview">
<sl-resize-observer>
<div>
Resize this box and watch the console 👉
</div>
</sl-resize-observer>
</div>
<script>
const container = document.querySelector('.resize-observer-overview');
const resizeObserver = container.querySelector('sl-resize-observer');
resizeObserver.addEventListener('sl-resize', event => {
console.log(event.detail);
});
</script>
<style>
.resize-observer-overview div {
display: flex;
border: solid 2px rgb(var(--sl-input-border-color));
align-items: center;
justify-content: center;
text-align: center;
