我正在创建一个MVC4 Web应用程序项目.当我使用空项目并只是在浏览器上运行它工作正常.但问题是当我正在尝试创建一个Internet应用程序项目而不是Empty project.Once我创建互联网应用程序项目,当试图在浏览器上运行它时,它显示以下配置错误.我明白这是与MySQL连接器程序集引用相关的东西.以下是错误.

Server Error in '/' Application.

我想在div标签之后添加一个三角形.因此我在伪元素之后使用了css3.但它不起作用.以下是我的css规则.

.header-wrapper .part1 ::after {
    width: 0;
    height: 0;
    border-left: solid 48.35px #f21e1e;
    border-bottom: solid 48.35px transparent;
    border-top: solid 48.35px transparent;
}

以下是我的HTML部分

<div class="header-wrapper">
    <div class="part1"></div>
</div>
