缓动/过渡后窗格未调整大小

Question

我有这些 HAML (A) 和 Sass (B) 文件（在后台使用 i.compass 和 ii.cecer-easing-0.2 ）。

根据此示例，我想要对左窗格进行动画处理（水平扩展/收缩），并自动调整右窗格的大小。

我已经使用这些样式设置了我的父容器 { display: box; box-orient：水平； }。子 div 具有“box-flex”和缓动“过渡”。但右窗格没有调整大小。

我想知道我还必须在那里放什么？

谢谢

看来您不应该对 box-flex 的子级应用 position:absolute ，因为这会阻止它们在更改大小时相互“推动”。

解决方法是在 .main-content 上应用 position:absolute 并从那里定位：

.main-content
  @include display-box
  @include box-orient(horizontal)
  +stretch-y( $offset-top: $header-height, $offset-bottom: $footer-height )

.left-col
  width: $left-col-width
  @extend .stretched
  @include box-flex(1)
  @include ceaser-transition(easeInOutExpo, width, 500ms, 0s)

.left-col.closed
  width: 500px

.right-col
  @extend .stretched
  @include box-flex(1)
