I'm building an admin panel mockup. I need to create a sidebar navigation and I'm searching for a semantic way to do it. What is important: I need to place there also a footer.
I was thinking about something this way:
<div class="page-container">
<!-- Sidebar -->
<aside>
<div class="brand">
Brand
</div>
<nav>
....
</nav>
<footer>
Footer
</footer>
</aside>
<!-- Content -->
<div class="content-container">
....
</div>
</div>
To do everything right, follow the HTML5 specification. There is the aside element section specially for your case.
