这是一个Asp.Net MVC4应用程序

如果删除导航栏css navbar navbar-inverse navbar-fixed-top但模态位置仍位于左侧，则会删除此淡入淡出错误

所有上述相关链接都定义了相同的问题，但它们都没有帮助解决我的问题

Answer 1

您的示例中的

navbar navbar-fixed-top需要z-index > 1040

Answer 2

将您的代码更改为此

<!--===================navBar===================-->
<div class="navbar navbar-fixed-top"> 
<a href="#registration_modal" data-toggle="modal">
    Register
</a>
</div>
<!--===================modal====================-->
<div id="registration_modal" class="modal hide fade">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">×</button>
            <h3>Register An Account</h3>
    </div>

    <div class="modal-body">
        Registration form goes here.
    </div>

    <div class="modal-footer">
        <button class="btn btn-secondary" data-dismiss="modal">Cancel</button>
        <button class="btn btn-primary">Register</button>
    </div>

</div>
