這是一個Asp.Net MVC4應用程序

如果我刪除導航欄css navbar navbar-inverse navbar-fixed-top但模式位置仍在左側，則消除此淡入淡出錯誤

以上所有相關鏈接都定義了相同的問題，但它們均無助於解決問題

Answer 1

在您的示例中navbar navbar-fixed-top需要z-index > 1040

Answer 2

將您的代碼更改為此

<!--===================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>
