左边的侧边栏需要两侧

Question

我创建了一个侧栏，需要它从右侧和左侧出现（当前从左侧出现）所以如果您注意到提高响应的方法，我也可以估算一个待办事项列表如果您有很大的感激之情可以告诉我，由于某种原因，从汉堡包到x的转换仅适用于chrome，而不是在firefox时间来解决这个问题将非常感激（需要它出现在菜单点击上）

Answer 1

基本上，Firefox不会渲染从 hamburger 到 x 的过渡，因为您使用动画 来webkit-基于浏览器，因此Firefox 不适用。

在CSS更新中，使用供应商前缀进行转换的规则，并在底部写下标准声明。

为了举例：

  -webkit-transition: all 0.3s ease-out;  /* Android 2.1+, Chrome 1-25, iOS 3.2-6.1, Safari 3.2-6  */
  transition: all 0.3s ease-out;  /* Chrome 26, Firefox 16+, iOS 7+, IE 10+, Opera, Safari 6.1+  */
