<button onclick="alert('Hello!');">Say Hello!</button>
<p>My favorite language is <b>HTML</b>. Here are my others:</p>
<ol>
<li>CSS</li>
<li>JavaScript</li>
<li>PHP</li>
</ol>
</div>

Notice how every element has an opening tag, a closing tag, and text or other elements inside
the opening and closing tags. Void tags however, are shown in the example below:

<img src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png" />
<br>
<hr>
<input type="number" placeholder="Enter your favorite number">

With the exception of the img tag, all of these void elements have only an opening tag. The img
tag, unlike any other tag, has a self closing / before the greater than sign of the opening tag.
It is best practice to have a space before the slash.
