在MVC 4中使用Razor在默认css(site.css)中找不到Microsoft提供的默认css(site)中的类

Question

我使用了Microsoft提供的默认（Razor-cshtml）模板，使用 MVC.It 工作正常将数据插入数据库。现在，我添加了三个新的下拉列表，我想为其应用与文本框相同的外观。（文本框和下拉列表的宽度和样式应相同）。

Microsoft使用div class="editor-field and editor-label" 作为文本框（EditorFor） 和标签。但这不是申请下拉列表。为什么会这样？？

我什至想更改样式，例如：文本框的宽度和字体。怎么办？？

我在Microsoft提供的默认css（site.css）中搜索了这些类，但是我没有找到这些类。如何解决这个问题???

如何使用微软提供的默认css（site.css）为所有文本框和下拉列表制作统一的css。

请建议我一些方法。

我的 CSHTML 代码：

@model Sample.Models.Master.CompanyModel
@{
    ViewBag.Title = "Create";
}
<h2>Create</h2>
<br />
@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>CompanyModel</legend>
        <div class="editor-label">

Answer 1

像下面这样使用。

.cssclass{
width:auto!important;
}

您需要使用 important ，并使用 f5 重新加载浏览器，以便浏览器不会缓存。

Answer 2

根据丹尼尔·伊姆斯的回答说

我需要将类中的元素包装为：

HTML作为：

<div class="editor">
    <label class="editor-label">Test</label>
    <input class="editor-field" />
</div>

而不是：

<label class="editor-label">Test</label>
<input class="editor-field" />

CSS 作为：

.editor label { /**/ }
.editor input,
.editor select { /**/ }

而不是：

.editor-label { /**/ }
.editor-field { /**/ }

我们可以使用一些 javascript 来重新添加类：

var content = document.getElementById('content');
var labels = content.getElementsByTagName('label');
for (var i = 0; i < labels.length; i++) {
    labels[i].classList.add('editor-label');
    var id = labels[i].getAttribute('for');
    var input = document.getElementById(id);
    input.classList.add('editor-field');
}
