标签： html css

导航栏底部和背景图像之间有间隙。我看过我的代码，但我似乎无法解决它或找出问题所在。有什么帮助吗？

HTML：

<body>
<div class="landingContent">
        <input type="checkbox" id="navbar-checkbox" class="navbar-checkbox">

    <nav id="middle" class="menu">
                    <li><a href="#" id="logo-nav"> < /> </a></li>
        <ul>
            <li><a href="#" id="active">Home</a></li>
            <li><a href="#">Forum</a></li>
            <li><a href="#">Projects</a></li>
            <li><a href="#">Store</a></li>
            <li><a href="#">About</a></li>
            <li><a href="#">Contact</a></li>
        </ul>

        <label for="navbar-checkbox" class="navbar-handle"></label>
    </nav>

    <div class="content-main">
        <h1>System</h1>
        <p>"A new look into technology"</p>
        <center>
        <div class="first"><button class="button" id="btn-nw" type="button" onclick="smoothScroll(document.getElementById('second'))"><i class="fa fa-angle-double-down"></i></button></div>
    </center>
    </div>
</div>
<div class="otherContent">

</div>

您只是在content-main课程中添加了太多的保证金。
