title: Remove an Element Using jQuery

# --description--
Now let's remove an HTML element from your page using jQuery.
jQuery has a function called `.remove()` that will remove an HTML element entirely
Remove element `target4` from the page by using the `.remove()` function.
# --hints--
You should use jQuery to remove your `target4` element from your page.
```js
assert(
$('#target4').length === 0 && code.match(/\$\(["']#target4["']\).remove\(\)/g)
);
```
You should only use jQuery to remove this element.
```js
assert(
code.match(/id="target4/g) &&
!code.match(/<!--.*id="target4".*-->/g) &&
$('#right-well').length > 0
);
```
