Question

我有一个svg元素，正在对其进行无限的CSS旋转。我想要一个动作，可以在无限旋转中将此元素从其当前旋转角度旋转到特定角度。

我已经成功地使元素无限旋转，并旋转到所需的角度，但这并不是一个平稳的过渡。当应用新的旋转（rotateBack）时，在将元素旋转到50度之前，会将其重置为0度的原点。如何让rotateBack动画从当前旋转角度开始？

这是我当前的解决方案，其中不包括某些样式。

function refresh() {
  var refreshIcon = document.getElementById('refreshIcon');
  var refreshIconPath = document.getElementById('refreshIconPath');
  if (refreshIconPath.style.fill === 'rgb(186, 12, 47)') {
    refreshIconPath.style.fill = 'green';
    refreshIcon.style.webkitAnimation = 'rotateBack 1.5s forwards';
  } else {
    refreshIconPath.style.fill = 'rgb(186, 12, 47)';
    refreshIcon.style.webkitAnimation = 'rotation 1.5s infinite linear forwards';
  }
}

@-webkit-keyframes rotation {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(359deg);
  }
}

@-webkit-keyframes rotateBack {
  100% {
    -webkit-transform: rotate(50deg);
  }
}

<button class="refresh-button" onclick="refresh();">
    <svg class="refresh-icon" id="refreshIcon" width="36pt" height="36pt" viewBox="0 0 36 36" version="1.1">
        <g id="surface1">
