  width: 100%;
  height: 100%;
  line-height: 40px;

}

.menu .menuContent ul li {
  display: inline-block;
  margin-left: 50px;
  margin-right: 50px;
  color: #2d3235;
  transition: opacity 0.3s ease 0.3s;
  cursor: pointer;
  position: relative;
}

.menu .menuContent ul li:hover:before {

  left: 60px;
  top: -30px;
  opacity: 0;
  right: 0;
  margin: auto;
}

.menu .menuContent ul li:after {

  opacity: 0;

  transform: rotate(-45deg) translate(-50%, -50%);
  top: 50%;
}

.menu.active span i:nth-child(2) {
  transform: translateX(-100px);
  opacity: 0;
}

.menu.active span i:nth-child(3) {

  top: 50%;
}

.menu span {
  width: 70px;
  height: 70px;
  position: absolute;

  cursor: pointer;
  background: #fafafa;
  z-index: 1;

  width: 45%;
  height: 2px;
  left: 0;
  right: 0;
  margin: auto;
  background-color: #ccc;
  transition: transform 0.3s ease, opacity 0.1s ease 0.1s;
}

.menu span i:nth-child(1) {
  top: 40%;
