动画固定位置侧边栏

Question

我试图让我的固定侧边栏滑入或只是一般地动画，但我似乎无法弄清楚如何做到这一点。我尝试添加一些过渡和常规动画，但它们似乎不起作用。如果可能的话，我需要保持它固定。任何帮助表示赞赏。

$('.open-menu').click(function() {
  $(".sidebar").toggleClass('open')
  $("body").toggleClass('no-scroll')
});

.wrap {
  margin-bottom: 54px;
}

.sidebar {
  background: black;
  width: 280px;
  height: calc(100% - 50px);
  position: fixed;
  -webkit-transform: translate3d(-100%, 0px, 0px);

形成.sidebar 删除display: none;，将.open 更改为.sideba.open 并删除display:block !important;

但说实话，你的 CSS 有点乱。您使用动画，但您没有声明 keyfrems。请阅读：https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Animations/Using_CSS_animations
