The link to #main
is the current page, so it works as a skip link.
<nav aria-label="Main menu">
<ul>
<li><a href="/">Home</a></li>
<li><a href="#main" aria-current="page">About us</a></li>
<li><a href="/services">Services</a></li>
<li><a href="/projects">Projects</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
</nav>
Note: this approach requires javascript to show/hide the list on click the button
<nav aria-label="Main menu">
<button aria-expanded="false">
<svg>...</svg>
Menu
</button>
<ul id="menu-list" hidden>
<li><a href="/">Home</a></li>
<li><a href="#main" aria-current="page">About us</a></li>
<li><a href="/services">Services</a></li>
<li><a href="/projects">Projects</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
</nav>
