Adding a subtitle to a Bootstrap Navbar - html

Question

I have a Bootstrap 4 website with a navbar. The navbar has a brand part with an image and title text, and then there's the rest of the navbar. You can see it here: https://jsfiddle.net/zmbq/aq9Laaew/218793/
Now, I want to add a subtitle, under the title "A Digital Onomasticon". The problem is - the substitle is long, and I want it to extend below the nav links.
I tried everything I could think of and couldn't figure out how to do that.
NOTE: the answer to this question is not sufficient, as it yields something like this: https://jsfiddle.net/zmbq/7et2uz0w/

Answer 1

Wrap the brand and links in a separate flexbox (d-flex) div...
<nav class="navbar navbar-light bg-light navbar-expand-sm flex-nowrap align-items-start">
<a class="navbar-brand" href="#">
<img src="http://onomasticon.researchsoftwarehosting.org/assets/images/seal-impression.png">
</a>
<div class="d-flex flex-column">
<div class="d-sm-flex d-block flex-nowrap">
<a class="navbar-brand" href="#">A Digital Onomasticon</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarOnavbarNavptions" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Item one</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Item two</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Item three</a>
</li>
</ul>
</div>
</div>
<small>A lot more text that goes under the links and should be cleverly placed, and isn't</small>
</div>
</nav>

Answer 2

You can set the subtitle to position absolute to remove it from the normal content flow. It's unclear how it should look on mobile, I simply hide it in the media query. Example:
<a class="navbar-brand" href="#">
<img src="http://onomasticon.researchsoftwarehosting.org/assets/images/seal-impression.png">
A Digital Onomasticon
<small>A lot more text that goes under the links and should be cleverly placed, and isn't</small>
</a>
.navbar-brand small {
display: block;
font-size: 10px;
white-space: normal;
position: absolute;
}
#media (max-width: 575.98px) {
.navbar-brand small {
display: none;
}
}
