我正在开发ASP.Net中的自定义菜单控件。

我已经在ASP.Net webform c#上为菜单创建了一个单独的新项目,最终获得了我想要的输出。

欲望输出

现在,当我将菜单控件css和其他HTML代码放在VB.Net上运行的应用程序中时,所有自定义css都消失了,ASP.Net默认的CSS Classes覆盖了它。以下是我目前的输出:

这是我的主页代码:

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />
<asp:Menu
        ID="Menu"
        runat="server"
        DataSourceID="SiteMapDataSource1"
        Orientation="Horizontal"
        OnMenuItemDataBound="OnMenuItemDataBound"
        IncludeStyleBlock="false"
        StaticEnableDefaultPopOutImage="false"
        CssClass="AHMenu">
        <LevelSubMenuStyles>
            <asp:SubMenuStyle CssClass="AHlevel1" />
            <asp:SubMenuStyle CssClass="AHlevel2" />
            <asp:SubMenuStyle CssClass="AHlevel3" />
            <asp:SubMenuStyle CssClass="AHlevel4" />
            </LevelSubMenuStyles>
            <LevelMenuItemStyles>
            <asp:MenuItemStyle CssClass="AHlevel1Style" />
            <asp:MenuItemStyle CssClass="AHlevel2Style" />
            <asp:MenuItemStyle CssClass="AHlevel3Style" />
            <asp:MenuItemStyle CssClass="AHlevel4Style" />
            </LevelMenuItemStyles>
</asp:Menu>

在浏览器视图源中,我的所有CSS都消失了,并使用默认CSS覆盖。如下图所示:

这是我的CSS:

#Menu > ul.AHlevel1 > li:hover {
  background-color: white;
}

#Menu > ul.AHlevel1 > li:hover a.AHlevel1Style {
  color: black !important;
}

.AHMenu {
