CSS动画条纹问题

标签： html css animation css-animations

我在下面有2个代码段。 在第一个，我有漂亮的条纹，他们调整自己的窗口大小，并始终居中（我尝试一些动画，但我不会像片段2中的动画那样得到它）

但我需要一个动画，这个动画显示在第二个片段中，条纹应该来自下方并且上升，我想在最终结果中保留它。

所以我需要与第一个和第二个片段融合。

首先：

＆＃13;
＆＃13; 
html,
body {
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
  #position: fixed;
}

.mask {
  height: 100%;
  overflow: hidden;
  position: relative;
}

.container {
  height: 100%;
  margin: 0 -100vh;
  #position: absolute;
}

.stripe {
  float: left;
  height: 100%;
  width: 2%;
  margin: 0 1%;
  bottom: 0%;
  max-height: 0%;
  #position: absolute;
  background-color: black;
  transform: skew(-20deg);
  #transform-origin: bottom bottom;
  #transform-origin: left bottom;
  animation: ani 1s linear 1 forwards;
}

.stripe:nth-child(1) {
  animation-delay: 0.0s;
}

.stripe:nth-child(2) {
  animation-delay: 0.2s;
}

.stripe:nth-child(3) {
  animation-delay: 0.4s;
}

.stripe:nth-child(4) {
  animation-delay: 0.6s;
}

.stripe:nth-child(5) {
  animation-delay: 0.8s;
}

.stripe:nth-child(6) {
  animation-delay: 1s;
}

.stripe:nth-child(7) {
  animation-delay: 1.2s;
}

.stripe:nth-child(8) {
  animation-delay: 1.4s;
}

.stripe:nth-child(9) {
  animation-delay: 1.6s;
}

.stripe:nth-child(10) {
  animation-delay: 1.8s;
}

.stripe:nth-child(11) {
  animation-delay: 2s;
}

.stripe:nth-child(12) {
  animation-delay: 2.2s;
}

.stripe:nth-child(13) {
  animation-delay: 2.4s;
}

.stripe:nth-child(14) {
  animation-delay: 2.6s;
}

.stripe:nth-child(15) {
  animation-delay: 2.8s;
}

.stripe:nth-child(16) {
  animation-delay: 3s;
}

.stripe:nth-child(17) {
  animation-delay: 3.2s;
}

.stripe:nth-child(18) {
  animation-delay: 3.4s;
}

.stripe:nth-child(19) {
  animation-delay: 3.6s;
}

.stripe:nth-child(20) {
  animation-delay: 3.8s;
}

.stripe:nth-child(21) {
  animation-delay: 4s;
}

.stripe:nth-child(22) {
  animation-delay: 4.2s;
}

.stripe:nth-child(23) {
  animation-delay: 4.4s;
}

.stripe:nth-child(24) {
  animation-delay: 4.6s;
}

.stripe:nth-child(25) {
  animation-delay: 4.8s;
}

@keyframes ani {
  0% {
    max-height: 0%;
  }
  100% {
    max-height: 100%;
  }
}

我改变了你的布局。

但主要区别在于从渐变的背景中获取动画效果并移动此渐变。以这种方式处理条纹位置要容易得多：

html,
body {
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
}

.mask {
  height: 100%;
  overflow: hidden;
  position: relative;
}

.container {
  height: 100%;
  margin-right: -100vh;
}

.stripe {
  display: inline-block;
  height: 100%;
  width: 2%;
  margin: 0 1%;
  bottom: 0%;
  transform: skew(-20deg);
  transform-origin: top;
      background-image: linear-gradient(to top, black 50%, transparent 50%);
    background-size: 100% 200%;
    animation: ani 1s forwards;
}

.stripe:nth-child(1) {
  animation-delay: 0.0s;
}

.stripe:nth-child(2) {
  animation-delay: 0.2s;
}

.stripe:nth-child(3) {
  animation-delay: 0.4s;
}

.stripe:nth-child(4) {
  animation-delay: 0.6s;
}

.stripe:nth-child(5) {
  animation-delay: 0.8s;
}

.stripe:nth-child(6) {
  animation-delay: 1s;
}

.stripe:nth-child(7) {
  animation-delay: 1.2s;
}

.stripe:nth-child(8) {
  animation-delay: 1.4s;
}

.stripe:nth-child(9) {
  animation-delay: 1.6s;
}

.stripe:nth-child(10) {
  animation-delay: 1.8s;
}

.stripe:nth-child(11) {
  animation-delay: 2s;
}

.stripe:nth-child(12) {
  animation-delay: 2.2s;
}

.stripe:nth-child(13) {
  animation-delay: 2.4s;
}

.stripe:nth-child(14) {
  animation-delay: 2.6s;
}

.stripe:nth-child(15) {
  animation-delay: 2.8s;
}

.stripe:nth-child(16) {
  animation-delay: 3s;
}

.stripe:nth-child(17) {
  animation-delay: 3.2s;
}

.stripe:nth-child(18) {
  animation-delay: 3.4s;
}

.stripe:nth-child(19) {
  animation-delay: 3.6s;
}

.stripe:nth-child(20) {
  animation-delay: 3.8s;
}

.stripe:nth-child(21) {
  animation-delay: 4s;
}

.stripe:nth-child(22) {
  animation-delay: 4.2s;
}

.stripe:nth-child(23) {
  animation-delay: 4.4s;
}

.stripe:nth-child(24) {
  animation-delay: 4.6s;
}

.stripe:nth-child(25) {
  animation-delay: 4.8s;
}

@keyframes ani {
  0% {
    background-position: 100% 0%;
  }
  100% {
    background-position: 100% 100%;
  }
}
