css - 在导航栏菜单中滚动已修复

Question

我有这段代码(这是 Bootstrap 固定导航栏菜单):

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
        <div class="container-fluid container_mop">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>

            </div>
            <a class="navbar-brand" href="#"><img src="images/logo.png" class="center img-responsive logo_top"></a>
            <div class="collapse navbar-collapse" id="navbar-collapse-1">

                <ul class="nav navbar-nav navbar-left navbar_odstep">
                    <li class="mopy_menu_1"><a href="#">O mnie</a></li>
                    <li class=" mopy_menu_1 dropdown ">
                        <a href="#" class="mopy_menu_2 navbar_cor_1" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">gabinet <span class="caret"></span></a>
                        <ul class="dropdown-menu dropdownPadding">
                            <li class=" mopy_menu_dropdown"><a href="#">- Gdzie przyjmuje </a></li>
                            <li class=" mopy_menu_dropdown"><a href="#">- Badania </a></li>

@media(max-width: 480px) {

    .odstepNadMenuFront {
       background-color: red;
      height: 120px;
  }

    .logo_top {
      padding-top: 50px;
        width: 90%;
  }

  .navbar_odstep {

      padding-bottom: 0px;
  }

    .navbar_odstep{
        padding:0 ;
    }

}

当我有 480px 宽度时，我在菜单中滚动时遇到问题(在菜单中单击“gabinet”后 - 打开子菜单后)。在桌面分辨率方面我没有任何问题。

有人知道怎么解决吗？该网站使用 Bootstrap 3

Answer 1

max-height 是在 bootstrap 中指定的，所以你需要通过添加下面的 css 来覆盖它

.navbar-fixed-bottom .navbar-collapse, .navbar-fixed-top .navbar-collapse {
    max-height: 100% !important;
}
