How to use

HTML structure

The navigation menu uses a c787b9a589a3ece771e842a6176cf8e9 element to wrap an unordered list.

<nav>
  <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">Docs</a></li>
      <li><a href="#">Demos</a></li>
      <li><a href="#">中文</a></li>
  </ul>
</nav>

CSS Style

When the mouse slides over the menu item in this navigation menu, the menu item has a slight tilt animation, and two lines will slide out above and below the menu item. The menu item's tilt animation uses the transform attribute to rotate and scale the hyperlink element when the menu item is rolled over by the mouse.

li a {
    display: block;
    font-size: 20px;
    text-align: center;
    padding: 10px 15px;
}
 
li a:hover {
    transform: rotate(5deg) scale(1.1);
}

The upper and lower lines of the menu item are made using the :before and :after pseudo-elements of the hyperlink element. They start with 0 transparency and 0 width, and use the transform property to rotate and move them.

li a:before, li a:after {
    opacity: 0;
    border-top: 1px solid white;
    content: '';
    display: block;
    position: relative;
    z-index: -1;
    margin: auto;
    width: 0px;
}
 
li a:before {
    top: 0px;
    transform: rotate(120deg) translateY(-50%) translateX(-50%);
}
 
li a:after {
    top: 5px;
    transform: rotate(-60deg) translateY(-50%) translateX(-50%);
}

As the mouse rolls over, their transparency changes to 1, their width is set to 20 pixels, and they use a smooth transition of the ease effect.

li a:hover:before, li a:hover:after{
    transition: all 0.3s ease;
    opacity: 1;
    width: 20px;
}
