Basic tags are links to respective pages, for example blog posts about a specific tag.
For “Dismiss” tags, they should include data that can be added/dismissed. For example, a hidden form input.
<span class="tag tag--dismiss tag--large">
<span class="tag__title">Unde</span>
<button type="button" class="tag__dismiss js--dismiss">⨉</button>
</span>
<span class="{{modifier 'tag' modifiers}}">
<span class="tag__title">{{ titlecase text }}</span>
<button type="button" class="tag__dismiss js--dismiss">⨉</button>
</span>
