html - 导航栏下 100% 宽度的 div 显示滚动条

问题描述

嘿伙计们，我希望你做得很好，所以我正在处理一个页面。主要有一个导航栏，在该导航栏下方有一个引导网格和一个页脚..所以我想显示页面，因为导航栏和页脚之间的网格覆盖了 em 之间的空间，为此我使用了 100% 的宽度作为行但是它似乎有效。这是我的代码。因此它成为每个设备的单个页面。没有滚动条

    <div class="container-fluid">
        <div class="row my_row">
            <div class="col-md-2">
                www
            </div>
            <div class="col-md-8">

    </div>
    <nav class="navbar navbar-bottom navbar-light bg-faded">
  <a class="navbar-brand" href="#">Fixed bottom</a>
</nav>
</body>
</html>

我的CSS：

* { margin:0; padding:0; }
.main_nav {
    background: #006080;
}
.logo {
    margin-left: 10px;
}
.my_row > div {
    border: 1px solid black;
}
.my_row {
    height: 100%;
}

标签： htmlcssnavbar

解决方案

只需添加溢出：隐藏到 CSS 的主体

body{
overflow:hidden;
}

* { margin:0; padding:0; }
.main_nav {
    background: #006080;
}
.logo {
    margin-left: 10px;
}
.my_row > div {
    border: 1px solid black;
}
.my_row {
    height: 100%;
}
