Appending Image to Overlay Div?

The way the code is written, when we append $image to $overlay I imagine the <img> tag going after the <div> tags opposed to in between them?

This is how I visualize it after being appended...

<div id="overlay"></div>
<img>  // img is after

How is it that the <img> goes between? This is how I believe the result should look....

<div id="overlay">
  <img>  // img is between
</div>

Instructors code

const $overlay = $('<div id="overlay"></div>');
const $image = $('<img>');

$overlay.append($image);

jQuery's append() is used to add one element INTO another. One thing you would note, though, if that particular DIV contained other elements, an H1 for example, the append would add that IMG element after the H1, but still inside of the DIV.

You can read a little more about how append() works in the jQuery documentation: http://api.jquery.com/append/

OK great! That makes perfect sense to me now.
