如图。input文本框输入内容不显示，placeholder属性的值也没有显示，给input文本框加个什么css属性可以使这些内容显示出来？
以下是代码：
<div class="tpl-block ">
<div class="am-g tpl-amazeui-form">
<div class="am-u-sm-12 am-u-md-9">
<form class="am-form am-form-horizontal">
<div class="am-form-group">
<label for="user-name" class="am-u-sm-3 am-form-label">姓名 / Name</label>
<div class="am-u-sm-9">
<input type="text" class="input" id="user-name" placeholder="姓名 / Name">
<small>输入你的名字，让我们记住你。</small>
</div>
</div>
</form>
</div>
</div>
</div>
