Fullscreen Sliding Navigation Menu Plugin With jQuery - expandyMenu

expandyMenu is a fancy jQuery navigation plugin used to create a fullscreen sliding menu that reveals the background on mouse hover.

How to use it:

1. Create the menu items as follows:

<div id="menu" class="menu-container">
  
  <div id="item-1" class="menu-item red">
    <h1>Menu 1</h1>
    <p>Description here</p>
  </div>
  <div id="item-2" class="menu-item blue">
    <h1>Menu 2</h1>
    <p>Description here</p>
  </div>
  <div id="item-2" class="menu-item d-blue">
    <h1>Menu 3</h1>
    <p>Description here</p>
  </div>
  <div id="item-3" class="menu-item green">
    <h1>Menu 4</h1>
    <p>Description here</p>
  </div>
  <div id="item-4" class="menu-item yellow">
    <h1>Menu 5</h1>
    <p>Description here</p>
  </div>

</div>

2. Create a toggle link for the navigation menu.

<a class="cd-nav-trigger cd-text-replace" href="#primary-nav" id="toggle">
  <span aria-hidden="true" class="cd-icon"></span>
</a>

3. The primary CSS styles for the navigation menu.

#menu { overflow: hidden; }

#menu>* {
  display: block;
  overflow: hidden;
}

.menu-item {
  width: 25%;
  height: 100%;
  display: block;
  position: absolute;
  float: left;
  -webkit-transform: translateY(-100%);
  transform: translateY(-100%);
  transition: transform 300ms linear;
  will-change: transform;
  pointer-events: auto;
}

.menu-item.active {
  -webkit-transform: translateY(0%);
  transform: translateY(0%);
  transition: transform 300ms linear;
}

h1 {
  font-size: 2.9vw;
  color: #ffffff;
  top: 15%;
  width: 260px;
  text-transform: uppercase;
  text-align: center;
  margin-left: -130px;
  left: 50%;
  z-index: 100;
}

.menu-item p {
  opacity: 0;
  text-align: center;
  margin-left: -130px;
  left: 50%;
  z-index: 100;
  top: 30%;
  width: 280px;
  color: #ffffff;
  -webkit-transition: opacity 0.5s, height 0.4s;
  -moz-transition: opacity 0.5s, height 0.4s;
  transition: opacity 0.5s, height 0.4s;
}

.menu-item.menu-expanded p { opacity: 1; }

.menu-item>* {
  position: absolute;
  will-change: transform;
}
 @media screen and (max-width: 768px) {

.menu-horizontal .menu-item {
  width: 100%;
  float: none;
  position: relative;
  height: 250px;
  -webkit-transform: translateX(-100%);
  transform: translateX(-100%);
  transition: transform 300ms linear;
}

.menu-horizontal .menu-item.active {
  -webkit-transform: translateX(0%);
  transform: translateX(0%);
  transition: transform 300ms linear;
}
}

.menu-item:after {
  content: '';
  position: absolute;
  opacity: 0;
  top: 0;
  left: 0;
  height: 100vh;
  width: 100%;
  background-image: url("bg.jpg");
  background-repeat: no-repeat;
  background-position: center center;
  background-size: cover;
  -webkit-transition: opacity 0.5s, height 0.4s;
  -moz-transition: opacity 0.5s, height 0.4s;
  transition: opacity 0.5s, height 0.4s;
}

.menu-item.menu-expanded:after {
  opacity: 1;
  -webkit-transform: scale(1);
  -moz-transform: scale(1);
  -ms-transform: scale(1);
  -o-transform: scale(1);
  transform: scale(1);
}

4. Style the menu trigger.

.nav-trigger {
  position: absolute;
  z-index: 9999;
  top: 24px;
  right: 5%;
  height: 52px;
  width: 52px;
  border-radius: 50%;
  background-color: rgba(0, 0, 0, 0.8);
  -webkit-transition: background 0.2s;
  -moz-transition: background 0.2s;
  transition: background 0.2s;
}

.nav-trigger .nav-icon, .nav-trigger .nav-icon::before, .nav-trigger .nav-icon::after {
  /* menu icon created in CSS */
  position: absolute;
  background-color: #ffffff;
  border-radius: 2px;
  /* Force Hardware Acceleration in WebKit */
  -webkit-transform: translateZ(0);
  -moz-transform: translateZ(0);
  -ms-transform: translateZ(0);
  -o-transform: translateZ(0);
  transform: translateZ(0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
}

.no-touch .nav-trigger:hover { background-color: black; }
