如何使用 CSS 变换以抛物线路径 ie.curved 移动图片？

Question

我正在尝试沿抛物线（圆的 25%）路径移动图像，有人可以帮忙吗。我已尝试多次使用 csstransform: rotate(18deg) translate(0px,100px)围绕我的确切代码移动它如下 -

*{
    margin: 0;
    padding: 0;
}
.dash{
    position: absolute;
    top: 70%;
    left: 40%;
    width:50px;
    height:50px;
    background: #000;
    animation: animate 5s linear infinite;
    transform-origin: top;
}
@keyframes animate{
    0%{
        transform: rotate(0deg) translate(0px , 0px);
    }
    10%{
        transform: rotate(-5deg) translate(0px,-50px);
    }
    20%{
        transform: rotate(-15deg) translate(0px,-100px);
    }
    40%{
        transform: rotate(-20deg) translate(0px,-150px);
    }
    60%{
        transform: rotate(-30deg) translate(0px,-200px);
    }
    80%{
        transform: rotate(-35deg) translate(0px,-250px);
    }
    100%{
        transform: rotate(0deg) translate(0px,-300px);
    }
}

Answer 1

您可以像下面这样简单地做：

.dash {
  position: absolute;
  top: 0;
  left: 0;
  width: 50px;
  height: 50px;
  background: #000;
  animation: animate 2s linear infinite alternate;
}

@keyframes animate {
  0% {
    transform: rotate(90deg) translate(150px);
  }

  100% {
    transform: rotate(0deg) translate(150px);
  }
}

html {
  background:radial-gradient(circle 170px at top left,transparent 95%,#000,transparent) fixed;
}

<div class="dash"></div>

也喜欢这个：

.dash {
  position: absolute;
  top: 0;
  left: 0;
  width: 50px;
  height: 50px;
  background: #000;
  animation: animate 2s linear infinite alternate;
}

@keyframes animate {
  0% {
    transform: rotate(90deg) translate(150px) rotate(-90deg);
  }

  100% {
    transform: rotate(0deg) translate(150px) rotate(0);
  }
}

html {
  background:radial-gradient(circle 170px at top left,transparent 95%,#000,transparent) fixed;
}

<div class="dash"></div>
