I would call this classically “URL” - a link to a live-example. This is the site of my main client.
I’m not earning my living with graphic design - I do it behind my job. Mainly for him to be precise. It has been done in FreewayPro - the editor of my choice the last decade (unfortunately retired).
Ah - you can give it an ID or class name up to your liking. But a DIV is a DIV and a Section is a Section or cody spoken:
<div class="my-name-whatever">
<p>Some content</p>
</div>
or
<div ID="My-unique-name-never-appears-twice-on-the-same-page">
<p>And certainly some content here as well</p>
</div>
Cheers
