Radial Popup Menu In Pure CSS – Circle Menu

Yet another circle menu navigation concept to create a floating action button that reveals a radial popup menu when toggled.

Built with pure HTML and CSS/CSS3. No JavaScript required.

How to use it:

Create the radial popup menu from a regular html unordered list. In this example, we’re going to use Font Awesome 5 for the icons.

<link rel="stylesheet" 
      href="https://use.fontawesome.com/releases/v5.0.13/css/all.css" 
      integrity="sha384-DNOHZ68U8hZfKXOrtjWvjxusGo9WQnrNx2sqG0tfsghAvtVlRW3tvkXWZh58N9jp"

<ul id="menu"&gt;
  <a class="menu-button icon-plus" href="#menu" title="Show navigation"><span class="fas fa-share-alt"></span></a>
  <a class="menu-button icon-minus" href="#0" title="Hide navigation"><span class="fas fa-share-alt"></span></a>
  <li class="menu-item">
      <a href="#menu">
          <span class="fab fa-github"></span>
      </a>
  </li>
  <li class="menu-item">
      <a href="#menu">
          <span class="fab fa-facebook"></span>
      </a>
  </li>
  <li class="menu-item">
      <a href="#menu">
          <span class="fab fa-twitter"></span>
      </a>
  </li>
  <li class="menu-item">
      <a href="#menu">
          <span class="fab fa-instagram"></span>
      </a>
  </li>
</ul>
