:root {
  --primary--color: rgba(13, 110, 139, 0.75);
  --secondary-color: rgba(229, 148, 0, 0.9);
  --overlay-color: rgba(24, 39, 51, 0.85);
  --menu-speed: 1s;
}
/* reset */
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}
body {
  font-family: Arial, Helvetica, sans-serif;
  line-height: 1.4;
}
.container {
  max-width: 960;
  margin: 0 auto;
  overflow: hidden;
  padding: 0 3rem;
}
#showcase {
  background-color: var(--primary--color);
  color: #fff;
  height: 100vh;
  position: relative;
}
#showcase:before {
  content: '';
  background: url('../img/1.jpg') no-repeat center center/cover;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -1;
}

#showcase .showcase-container {
  display: flex;
  /* 竖向排序 */
  flex-direction: column;
  /* 上下居中 */
  justify-content: center;
  /* 上下居中 */
  align-items: center;
  text-align: center;

}

/* toggler animation */

.menu-wrap .toggler:checked + .hamburger > div {
  transform: rotate(135deg);
}
/* turn linex into */
.menu-wrap .toggler:checked + .hamburger > div:before,
.menu-wrap .toggler:checked + .hamburger > div:after{
  top: 0px;
  transform: rotate(90deg);
}
.menu-wrap .toggler:checked:hover + .hamburger > div {
  transform: rotate(225deg);
}
/* show menu */
.menu-wrap .toggler:checked ~ .menu{
  /* 可见 */
  visibility: visible;
}
.menu-wrap .toggler:checked ~ .menu > div {
  transform: scale(1);
  transition:var(--menu-speed);
}
.menu-wrap .toggler:checked ~ .menu > div > div {
  opacity: 1;
  transition: opacity 0.4s ease 0.4s;
}
