md-card 中的两个 md-content 彼此相邻

Two md-content next to eachother in md-card

我试图在一张 md 卡中获取 2 个内容 "boxes"。一个用户可以输入一些文本字段,而在另一侧我想要一个徽标。

<md-card ng-controller="AuthenticationController">
    <md-content class="left_side" layout-align="center center">

    </md-content>

    <md-content class="right_side" layout-align="right">

    </md-content>
</md-card>

CSS

    .left_side {
   height: 100%;
   width: 50%;
   background-color: blue;
   display: flex;
 }

    .right_side {
  height: 100%;
  width: 50%;
  background-color: red;
  display: flex;
  margin-right: 0px;
}

我认为这很简单,但不知何故我一直想错了,因为我不明白。

这对我有用

<div ng-controller="AppCtrl" class="md-padding selectdemoBasicUsage" ng-cloak="" ng-app="MyApp" id="container">
    <md-content class="md-padding" layout-xs="column" layout="row" layout-align="center center">
        <div flex-xs flex-gt-xs="70" layout="column" layout-align="center center">
            <md-card layout="row" ng-controller="AppCtrl" layout-align="center center">

                <md-content class="left_side" layout-align="center center" layout="column">

                    <md-content id="headerTxt">Welkom!</md-content> <br>
                    <md-content id="formContent" md-colors="orange">
