背景图像不能很好地与粘性页脚一起使用

Question

因此，在我当前的 HTML 和 CSS 设置下，我的内容的背景图像会因页脚而中断，这并不是我想要的。案例及要点：http://droppinghike.nl/gallerij.html

我的 HTML：

<div class="container">
    <header>
        <h1 id="title">Dropping Hike</h1>
        <ul id="nav">
            <li><a class="nav-link" id="active" href="#">Home<div class="nav-underline"></div></a></li>
            <li><a class="nav-link" href="aanmelden.html">Aanmelden<div class="nav-underline"></div></a></li>
            <li><a class="nav-link" href="deelnemers.html">Deelnemers<div class="nav-underline"></div></a></li>
            <li><a class="nav-link" href="gallerij.html">Gallerij<div class="nav-underline"></div></a></li>
            <li><a class="nav-link" href="contact.html">Contact<div class="nav-underline"></div></a></li>
            <li><a class="nav-link" href="faq.html">FAQ<div class="nav-underline"></div></a></li>
        </ul>
    </header>

    <div class="row">
        <h3 class="section">Welkom</h3>

任何想法或建议将不胜感激！ :)

Answer 1

您可以从页脚的 hr 中删除默认的上边距：

hr {
  margin-top: 0;
}

目前默认的 hr 将整个页脚向下推到它应该在的位置以下。

如果您想在较长的页面上保留内容和页脚之间的空间，可以在此处在主容器和页脚之间添加<br />：

编辑： 使主要内容全高而不是将页脚推到底部：

html {
    height: 100%;
}
body {
    min-height: 100%;
    margin-bottom: 0;
}
.container {
    min-height: 100%;
}
