身体边界没有到达身体的底部

标签: html css border spacing

我正在尝试在我的网页的整个主体周围创建边框,但每当我在身体标签周围放置边框时,它都无法到达底部。此外,由于某种原因,在页面的正文和底部之间有一个空格。请指教!

以下是代码:(请参阅https://jsfiddle.net/04tpunop/

HTML:

<!DOCTYPE html>
<body>
    <header>
        <nav>
            <div id="navBar">
          <a class="hdrBtn">Button</a>
                    <a class="hdrBtn">Button</a>
            </div>
        </nav>
    </header>
    <div id="banner">
            <h1>Content</h1>
            <h1>Content</h1>
            <h1>Content</h1>
    </div>
    <div id="content">
            <h1>Content</h1>
            <h1>Content</h1>
            <h1>Content</h1>
            <h1>Content</h1>
            <h1>Content</h1>

我认为你的身体可能只是包裹内容。尝试在CSS中将高度设置为100%。

如果这不起作用,请尝试将内容包装在高度和宽度设置为100%的DIV中

您需要从#banner中删除position: fixed;,从#content

删除position: relative;

还需要在标题中增加top: 0;的值以显示顶部边框
