  background-size: contain;
}

.bounce {
  animation: bounce 2s infinite;
}

@keyframes bounce {
  0%, 20%, 50%, 80%, 100% {
    transform: translateY(0);
  }
  40% {
    transform: translateY(-30px);
  }
  60% {
    transform: translateY(-15px);
  }
}

background image中的图片为黑色。我想改变这个图像的颜色。我可以添加叠加层吗？或者我 有 来创建新的svg + xml; base64图像？因为我不知道该怎么做。

Answer 1

你不能这样做。您将不得不创建另一个图像。
