You can turn most of the HTML elements into clickable links if you surround them with an anchor tag.
A link is is exactly what it sounds like, its a “link” to some other website or webpage i.e. when you click it, it takes you to some other resource on the internet.
You have created links in the previous challenges but you were only using normal text until now. for example:
<a href="link-to-a-website"> Website name </a>
Note that the user will only see “Website name” and when they click on it, the browser will take them to “link-to-a-wesbite” (assuming such a website exists).
The same concept applies to images. You can turn images into clickable links if you surround them with an a tag. the user will only see the image but it will also be a link to some other website.
