Animated Hexagon Menu with JavaScript, SVG and CSS3

A creative animated hexagon menu with triangle menu items & subtle hover effects built on top of SVG, CSS/CSS3 and a little JavaScript magic.

How to use it:

The html to create a SVG based hexagon navigation with six sub menus.

<nav id="hexNav">
  <div id="menuBtn"> <svg viewbox="0 0 100 100">
    <polygon points="50 2 7 26 7 74 50 98 93 74 93 26" fill="none" stroke-width="4" stroke="#585247" stroke-dasharray="0,0,300">
    </svg> <span></span> </div>
  <ul id="hex">
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="1.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="2.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="3.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="4.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="5.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
    <li class="tr">
      <div class="clip"><a href="#" class="content"> <img src="6.jpg">
        <h2 class="title">Title</h2>
        <p>Description</p>
        </a></div>
    </li>
  </ul>
</nav>
