Change the underline's opacity. Requires adding `.link-underline` to first set an `rgba()` color we use to then modify the alpha opacity.
{{< example >}}
+<p><a class="link-offset-2 link-underline link-underline-opacity-0" href="#">Underline opacity 0</a></p>
<p><a class="link-offset-2 link-underline link-underline-opacity-10" href="#">Underline opacity 10</a></p>
<p><a class="link-offset-2 link-underline link-underline-opacity-25" href="#">Underline opacity 25</a></p>
<p><a class="link-offset-2 link-underline link-underline-opacity-50" href="#">Underline opacity 50</a></p>
Just like the `.link-opacity-*-hover` utilities, `.link-offset` and `.link-underline-opacity` utilities include `:hover` variants by default. Mix and match to create unique link styles.
{{< example >}}
-<a class="link-offset-2 link-offset-3-hover link-underline link-underline-opacity-25 link-underline-opacity-75-hover" href="#">
- Underline opacity 10
+<a class="link-offset-2 link-offset-3-hover link-underline link-underline-opacity-0 link-underline-opacity-75-hover" href="#">
+ Underline opacity 0
</a>
