AngularJS Material 具有弹性布局重叠的卡片

Question

我有一个页面有一些 AngularJS Material 卡片需要排列成两列。最后一张卡片应以全宽显示在两列下方。但是，卡片 #3 和 #4（取决于宽度）与最后一张卡片重叠。我花了几个小时调试它，但就是找不到为什么会这样。

这是我的代码：

    angular.module('app', ['ngMaterial']).controller('ctrl', function() {});

实际上，如果您运行此处的代码会按预期出现，但如果它是一个单独的 HTML 文件，则不会。很奇怪。

Answer 1

我已经为该代码段创建了 this codepen，即使将宽度更改为任何内容，它似乎也能正常工作。

这可能是浏览器问题，看起来不像是 Angular material 错误。

    angular.module('app', ['ngMaterial']).controller('ctrl', function() {});
