变黑后，它们会暂时恢复正常。
这是导航栏的代码。

如果我向导航按钮发送垃圾邮件，主页背景有时也会变黑。
我想这可能是因为脚本的原因。我尝试改变脚本的位置：在正文之后，在头部。还尝试向脚本添加异步属性，但没有结果。
如果您不使用这些代码行，请尝试删除它们
<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css"/>
<link rel="stylesheet" href="~/css/site.css" asp-append-version="true"/>
<link rel="stylesheet" href="~/Curriculum.styles.css" asp-append-version="true"/>
这些样式表可能是导致问题的原因。
