Returns an array of HTML elements whose width is larger than that of the viewport's.
- Use `HTMLElement.offsetWidth` to get the width of the `Document`.
- Use `Array.prototype.filter()` on the result of `Document.querySelectorAll()` to check the width of all elements in the document.
```js
const getElementsBiggerThanViewport = () => {
const docWidth = document.documentElement.offsetWidth;
return [...document.querySelectorAll('*')].filter(
el => el.offsetWidth > docWidth
);
};
```
```js
getElementsBiggerThanViewport(); // <div id="ultra-wide-item" />
```
