制作流畅的动画条纹div

Question

我正在制作一个流畅的动画条纹div,就像进度条一样.

CSS:

.animationStripes{
  width: 300px;
  height: 50px;
  background-image: repeating-linear-gradient(-45deg, rgb(0, 0, 0), rgb(0, 0, 0) 25px, blue 25px, blue 50px);
  -webkit-animation:progress 2s linear infinite;
  -moz-animation:progress 2s linear infinite;
  -ms-animation:progress 2s linear infinite;
  animation:progress 2s linear infinite;
}
@keyframes progress{
  0% {
    background-position: 0 0;
  }
  100% {
    background-position: -70px 0px;
  }
}

好吧，我只通过添加一件事并且不对我的原始代码进行任何更改就成功地解决了这个问题。只需添加即可background-size: 150% 100%;防止图像在右侧笨拙地剪切。
