I'm looking up HTML text format on MDN and I came across with the example below:
<address>
<p>
Chris Mills<br />
Manchester<br />
The Grim North<br />
UK
</p>
<ul>
<li>Tel: 01234 567 890</li>
<li>Email: [email protected]</li>
</ul>
</address>
So, Instead of using the <br/> tag to separate the <p> content, can I use the <pre> tag? Further than that, can I use it in any context I want some linebreaks?

The
<pre>tag cannot be used.This is because
<pre>defines if it is shown exactly like what is written in your source code, in monospace, and that it is pre-formatted text. Just like the comment above, you can use CSS white space.
