Question

我正在关注https://material.angularjs.org/latest/layout/alignment上的文档。

我正在尝试垂直和水平对齐我的div，它适用于水平对齐但不适用于垂直对齐。 div的来源如下：

<div layout="column" layout-align="center center" class="text-center">
  <md-content>
    <h2>Test h2</h2>
  </md-content>
  <form ng-controller="LoginController as login" ng-submit="login.login()"
    ng-cloak class="text-center">
    <md-content>
      Login or ,<br/>
      register test br
      <md-input-container class="md-block">
        <label>Your email address</label>
        <input ng-model="login.user.email" type="email" required>
      </md-input-container>
      <md-input-container class="md-block">
        <label>Your password</label>
        <input ng-model="login.user.password" type="password" required>
      </md-input-container>
      <div class="md-block">
        <md-button type="submit" class="md-raised md-primary">Log in</md-button>
      </div>
    </md-content>
  </form>
</div>

这是什么问题？谢谢你的帮助

Answer 1

<div layout-align='center center' layout='column'>

这将仅将中心与直接子元素对齐。因此，将要对齐的所有元素包装为水平和垂直居中

<div layout-align='center center' layout='column'>
     <div>ABC</div>
     <div>XYZ</div>
</div>

看一下layout="column"之后的主要div和行。它们很重要。

<!DOCTYPE html>

          <div layout="row" layout-align="center start">

app.js

angular.module('app', ['ngMaterial']);

angular.module('app').controller('MainController', ["$scope", function($scope) {

}]);

使用角度材质垂直和水平对齐
