html - 在标题上方滑动移动导航

我正在尝试从移动设备的顶部创建滑动导航，但是我无法弄清楚为什么滑动导航位于标题的顶部。我希望标题始终在最前面，并且我尝试了z-index和position：绝对，但是并不能解决问题。

的HTML

<!-- Navigation -->
<nav class="topHeader clearfix">
    <div class="headerWrapper">

    <div class="logo">
        <a href="#">Logo</a>
    </div>

    <div class="navigation">
        <a href="#">Link</a>
        <a href="#">Link</a>
        <a href="#">Link</a>
        <a href="#">Link</a>
    </div>

    <div class="hamburgerMenu">
        <a href="#">
        <span></span>
        <span></span>
        <span></span>
        </a>
    </div>

    <div class="hamburgerNavigation">
        <a href="#">Link</a>
        <a href="#">Link</a>
        <a href="#">Link</a>
        <a href="#">Link</a>
    </div>

    </div>
</nav>

JAVASCRIPT

$(document).ready(function(){
    $('.hamburgerMenu').click(function(){
        $(this).toggleClass('open');
    });
});


$('.hamburgerMenu').click( function() {
    $(".hamburgerNavigation").toggleClass("show");
} );

最佳答案

您可以将top设置为.topHeader

.topHeader .headerWrapper .show {
    opacity: 1;
    transform: translate3d(0, 0vh, 0);
    top: 77px; // Added
}

或者您可以设置负数z-index

.topHeader .headerWrapper .show {
        opacity: 1;
        transform: translate3d(0, 0vh, 0);
        z-index: -1; // Added
    }
