Angular Material 未按应有的方式进行郊游

Lay outing with Angular Material not responding as it should

我正在尝试使用 angular material 构建一个登录表单。但我似乎无法获得预期的效果 -> http://gyazo.com/d31f624204524d8b1b6349c89b237be1

到目前为止我有这个 -> http://gyazo.com/0ab7343544a3c7992099c30684e062a1

任何人都可以帮助我使用这个 flex box 模型来布置我的应用程序

html 的代码是:

<div layout="row" flex layout-padding layout-fill layout-align="center center">
    <div>
        <md-card>
            <md-toolbar>
                <div class="padding-20 text-center">
                    <div>
                        <img src="../images/logo.png" alt="" width="177" height="162">
                    </div>
                    <h1 class="md-headline">Sign Up</h1>
                </div>
            </md-toolbar>

            <md-card-content class="md-padding">
                <form name="login">
                    <md-input-container>
                        <label for="email">Email</label>
                        <input id="email" label="email" name="email" type="email" />
                        <div ng-messages="login.email.$error"></div>
                    </md-input-container>

                    <md-input-container>
                        <label for="password">Password</label>
                        <input id="password" label="password" name="password" type="password" />
                    </md-input-container>
                </form>
            </md-card-content>
        </md-card>
    </div>
</div>

我的css:

body{
    background-image: url("../images/background.png");
    width: 1920px;
    height: 1080px;
    background-repeat: no-repeat;
    background-size: cover;
    overflow-x:hidden;
    overflow-y:hidden;
}

.padding-20 text-center{
    text-align: center;
    padding: 20px;
}

这是一个开始
