记录一些常用动画

        .flow-animation {
          position: relative;
          width: 300px;
          height: 1px;
          background-color: rgba(0,0,0,0);
          overflow: hidden;
        }

        .flow-animation::before {
          content: "";
          position: absolute;
          top: -50%;
          left: 0;
          right: 0;
          bottom: -50%;
          z-index: 999;
          background-color: white;

          /* 添加动画效果 */
          animation: flowAnimation 5s linear infinite;
        }

        @keyframes flowAnimation {
          0% { transform: rotateY(0deg); }
          100% { transform: rotateY(-360deg); }
        }

1.从左到右滑动线

@keyframes glowing {
  0% {
    background-position: 0 0;
  }
  50% {
    background-position: 100% 0;
  }
  100% {
    background-position: 200% 0;
  }
}
.element {
  background-image: linear-gradient(45deg, rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.5), rgba(0, 0, 0, 0));
  background-size: 400% 400%;
  animation: glowing 5s linear infinite;
  animation-direction: alternate;
}
