将角材料卡对齐在页面的中心 [英] aligning angular material card in center of the page

问题描述

我制作了一个注册脚本，允许用户注册我的网站。现在我遇到的问题是，注册界面所在的角度材料卡不在中心位置。我已经尝试了很多东西，包括< center> 和[layout-align =center center]，仍然没有任何作用
我的代码：

I made a Registration script which allows user to Sign Up to my site. Now the problem I am experiencing that the angular material card, in which the sign up interface lies, isn't at center. I've tried many things including <center> and [layout-align="center center"], still nothing works My code:

<md-content class="md-padding" layout-xs="column" layout="row">
    <div flex-xs flex-gt-xs="40" layout="column" layout-align="center center">
        <md-card class="card-40-center">
            <md-card-title>
                <md-card-title-text>
                    <span class="md-headline">Sign Up</span>
                </md-card-title-text>
            </md-card-title>
            <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" class="signup_form">
            <div class="md-padding" layout-align="center">
                <div layout="row">
            <md-input-container flex="100">
                <label>First name</label>
                <input>
            </md-input-container>
                <md-input-container flex="100">
                    <label>Last name</label>
                    <input>
