I am using Gatsby with React and have a navigation menu with links. I would like to make it so that when a link is clicked, a border bottom appears to indicate the current page, rather than only on hover.
<ul className="men" id="menu">
<li className="menuSob">
<Link className="menuItem" to="/about/">
About Magnet
</Link>
</li>
<li className="menuRep">
<Link className="menuItem" to="/representacoes/">
Representations
</Link>
</li>
<li className="menuServ">
<Link className="menuItem" to="/services/">
Services
</Link>
</li>
<li className="menuContent">
<Link className="menuItem" to="/content/">
Content
</Link>
</li>
<li className="menuCont">
<Link className="menuItem" to="/contact/">
Contact
</Link>
</li>
</ul>
