The example below does not include void elements:

<a href="/?originalUrl=https%3A%2F%2Friptutorial.com%2F%26quot%3Bhttp%3A%2F%2Fstackoverflow.com%2F%26quot%3B%26gt%3B%2520%2520%2520%2520%2520%2520%2520%2520%26lt%3Bh3%26gt%3BClick%2520here%2520to%2520visit%2520%26lt%3Bi%26gt%3BStack%2520Overflow!%26lt%3B%2Fi%26gt%3B%26lt%3B%2Fh3%26gt%3B%2520%2520%2520%2520%26lt%3B%2Fa%26gt%3B%2520%2520%2520%2520%26lt%3Bbutton%2520onclick%3D%26quot%3Balert("Hello!');">Say Hello!</button>

</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="/?originalUrl=https%3A%2F%2Friptutorial.com%2F%26quot%3Bhttps%3A%2F%2Fcdn.sstatic.net%2FSites%2Fstackoverflow%2Fcompany%2Fimg%2Flogos%2Fso%2Fso-icon.png%26quot%3B%2520%2F%26gt%3B%26lt%3Bbr%26gt%3B%26lt%3Bhr%26gt%3B%26lt%3Binput%2520type%3D%26quot%3Bnumber%26quot%3B%2520placeholder%3D%26quot%3BEnter%2520your%2520favorite%2520number%26quot%3B%26gt%3B%253C%2Fcode">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.
