I got this HTML:
<div class="row">
<div class="col-lg-6">
**<h1 id="primerbeneficio">Conoce a tu <span>lomito<span/> ideal</h1>**
<button id="descargaapple" type="button" class="btn btn-dark btn-lg download-button"><i class="fab fa- apple"></i> Download</button>
<button type="button" class="btn btn-outline-light btn-lg download-button"><i class="fab fa-google-play"></i> Download</button>
</div>
<div class="col-lg-6">
<img src="images/iphone6.png" class="title-image" alt="iphone-mockup">
</div>
</div>
And I just want to modify the word "lomito", but in my page also is affected the next word "ideal" with the same style.
The console shows this:

As it seems, another span tag involves both words, and "ideal" inherits somehow from h1.. but obviously my html doesn´t intend that.
I got bootstrap 5 with a CDN, but that shouldn´t be a problem, or is it?
I´ve already tried changing the html, but it can´t go any further than that, I mean, is just a tag..
