naturalWidth vs width

Written byPhuoc Nguyen

`naturalWidth` is the natural width of an element. It never changes. For example, a 100px wide image always has `naturalWidth` of 100px even when the image is resized by CSS or JavaScript.
Whereas, `width` is the value of `width` attribute. It is subject to change and can be updated via CSS or JavaScript.

Good to know

It's possible to get the natural width of an image that can be loaded by given `url`:
const getNaturalWidth = url => {
return new Promise((resolve, reject) => {
const img = new Image();
img.addEventListener('load', () => {
img.addEventListener('error', () => reject());
img.src = url;

// Usage
getNaturalWidth('https://path/to/image.png').then((naturalWidth) => {
