css - 动画固定位置边栏

Question

我正在尝试让我的固定侧边栏滑入或只是一般地设置动画，但我似乎无法弄清楚该怎么做。我试过只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，我需要保持它的固定。感谢您的帮助。

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

form .sidebar 移除display: none;，将.open改为.sideba.open并移除display:block !important;

但老实说，您的 CSS 有点乱。您使用动画但没有声明关键帧。请阅读:https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Animations/Using_CSS_animations
