+# simple-element-resize-detector
+
+Observes resizing of an element using a hidden iframe.
+
+
+## Installation
+
+```sh
+npm i -S simple-element-resize-detector
+```
+
+
+## Usage
+
+```js
+import observeResize from 'simple-element-resize-detector';
+
+// any DOM element that can have children
+let element = document.createElement('div');
+
+// listen for resize
+observeResize(element, () => {
+	console.log('new size: ', {
+		width: element.clientWidth,
+		height: element.clientHeight
+	});
+});
+```
+
+To stop observing resize events, simply remove the returned detector frame:
+
+```js
+let detector = observeResize(el, () => {});
+
+detector.remove();
+
+// or, for better browser compatibility:
+// detector.parentNode.removeChild(detector)
+```
