AngularJS具有弹性布局的材质卡重叠

Question

我有一个页面，其中包含一些AngularJS材质卡，需要将其分为两列。最后一张卡片应在两列下方显示完整宽度。但是，＃3和＃4卡（取决于宽度）与最终卡重叠。我花了几个小时来调试它，但无法找出原因。

这是我的代码：

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

这里是输出的相关部分：

实际上，如果您在此处运行代码，它会按预期显示，但如果是单独的HTML文件，则不会。很奇怪。

Answer 1

您缺少<!DOCTYPE html>，如果没有此选项，浏览器将以怪异模式呈现页面。

请参见Why do I need a doctype? (What does it do)

Answer 2

我为代码段创建了this代码笔，即使将宽度更改为任何值，它也似乎正常工作。

这可能是浏览器问题，似乎不是Angular的实质性错误。

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