The link element is a convenient way of creating a link. This can be an internal link to another page or an external link. This is adjustable in the CMS.
If you create an internal link and you change the url of that page, the link will be updated automaticly, so you won't end up with a dead link.
In the view file, this element is accessible by its name, for example
<a href="<?=$link;?>">This is a link</a>
<a href="https://webigniter.net">This is a link</a>
