我无法制作流畅的动画条纹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;
  }
}

问题在于背景图像渐变的最右侧存在奇怪的错位。我如何解决这个错位?

我设法通过添加一个东西并且不对我的原始代码进行任何修改来修复它。简单地添加background-size: 150% 100%;可以防止图像在右侧笨拙地剪裁。

使用百分比值制作线性渐变,而不是使用像素。应用背景大小,在您的情况下,我说background-size:50px 50px;,在关键帧中,移动背景,背景大小background-position: -50px 0px;

也是一个例子 http://plnkr.co/edit/HrSxkhYZaWp81fAQEaJn?p=preview
