我想定义一个类为必填字段添加星号，但我知道我继承的项目使用Razor mvc，并且它没有头部分将它放在我的cshtml文件的顶部。
这是我的_RegistrationStep1.cshtml表单的开头看起来像：
@{ Layout = null;}
@model MApplicationData.Models.ApplicantCapturedData
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="site-section">
<h4 class="site-header"><b>Department Contact Info:</b> (REQUIRED in case we have questions about this new applicant)</h4>
<hr />
@Html.HiddenFor(model => model.ID)
</div>
<div class="row">
<div class="col-xs-5">
<label class="control-label col-md-6" for="DeptContactName">Department Contact Name</label>
<div class="col-md-4">
@Html.EditorFor(model => model.DeptContactName, new { htmlAttributes = new { @class = "form-control", @required = "required" } })
@Html.ValidationMessageFor(model => model.DeptContactName, "", new { @class = "text-danger" })
</div>
</div>
...
我没有在我的网上搜索没有头部的cshtml文件中找到任何东西，但CSS definition确实说如果我不想在任何地方内联定义它的头部分。
我确实看到有关如何使所需字段的星号动态的信息，但我认为只需定义一个second class来添加asterisk就可以了。
ApplicantCapturedData.cs或Index.cshtml中没有头。我想也许它会以某种方式包括在内。搜索head的项目会在_Layout.cshtml中显示一个标签，该标签位于application / views / shared文件夹中，但是当我在那里添加所需的类信息时，运行该项目并未在必填字段上显示星号。这是_Layout.cshtml：

<!--I added this class-->
.required:after
{
content: "*";
font-weight: bold;
color:red;
}
</head>
这就是我在_RegistrationStep1.cshtml中使用所需类的方法：
<div class="row">
<div class="col-xs-5">
<label class="control-label col-md-6 required" for="DeptContactName">Department Contact Name</label><!--that is required class used-->
<div class="col-md-4">
@Html.EditorFor(model => model.DeptContactName, new { htmlAttributes = new { @class = "form-control", @required = "required" } })
@Html.ValidationMessageFor(model => model.DeptContactName, "", new { @class = "text-danger" })
</div>
</div>
...
_ViewStart.cshtml中有_Layout.cshtml的引用，它位于application / views文件夹中：
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
任何帮助确定所需的类不显示星号的原因将不胜感激。谢谢！
我看到你的布局中有一个/Content/Site.css。在那里，您可以编写您的css代码，并将应用于所有.cshtml文件中，并具有所需的输出。所以将此代码添加到Site.css：
label .required:after {
color: #e32;
content: ' *';
display:inline;
}
这是一个星号的样本，但是还有许多其他在线样本可以更好地适合你。有关详细信息，请参阅Mdn website
