嗨，我在导航栏中遇到了问题它会创建一个空白：screenshot html代码：

    <div class="header">
    <div class="overlay"></div>
    <nav class="navbar fixed-top navbar-expand-lg navbar-light bg-light">
        <a class="navbar-brand" href="#">Creative Agency</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item active">

如何在不出现此问题的情况下使导航栏固定（在顶部）！

我使用Bootstrap 4

注意：为主体添加padding-top无法解决此问题！

Answer 1

我通过addign解决了问题

padding-top: 48px;

到标题！
