Question

我正在投资组合网站上工作。我想弄清楚为什么我的主页上的主要部分延长到目前为止，但在其他页面上它停在内容正下方。这是代码。

所有网页的CSS：

body {
    background-color:#A6FFFF;
    width:100%;
}
#header, #main, #footer {
    display:block;
    position:relative;
    float:left;
}
#header, #footer {
    width:100%;
    height:15%;
}
#header {
    margin-bottom:2px;
    font-family:"Lucida Sans Unicode", "Lucida Grande", sans-serif;
}
#footer {
    margin-top:2px;
    text-align:right;
    border:2px;
}
#main {
    position:relative;
    width:70%;
    height:100%;
    margin:0 auto;
    background-color:#FFF;
    float:center;
}
#nav {
    list-style:none;
    margin:0;
    padding:0;
    text-align:center;
}
#nav li {
    display:inline;
}
#nav a {
    display:inline-block;
    padding:10px;
}

主页HTML：

<body>
<div class="auto-style1">
    <div id="header">Header
        <h1>Creative Minds Inc.</h1>
    </div>
    <div id="nav">Navigation

    <h2>Keyboard Shortcuts</h2>

    <h2>Cut, Copy, Paste shortcuts</h2>

    <p>The keyboard is not used as often as it could or should be. Sure it is used for typing documents or searches on the internet and such.
    <br>But do you really know how to use the keyboard to the best of your abilities? This is where I will show you the cut, copy, and paste shortcuts.
    <br>Now these are ways to make using the keyboard simplier instead of just using the mouse. So you yourself as a computer user can possibly be
    <br>more advanced and efficent. Now the keyboard functions are not hard to use. Below I will list the cut, copy, and paste keyboard shortcuts.
    <br>The keyboard shortcuts require you to hold down two different keys at the same time.</p>
    <p>First you will select the text or the image that you would like to cut or copy. When you do that it will look highlighted.</p>
    <p>Second you will press the control key. The control key is shown as <strong>ctrl</strong> on the keyboard next to the shift button.</p>
    <p>Third and finally, while you will continue holding down the <strong>ctrl</strong> key you will press either the x, c or v key for the desired function</p>

    <h2>CUT</h2>

    <p>The cut command or shortcut is used simply to remove texts or images from a screen that you are currently working on.
    <br>The cut shortcut moves the information to a place where it is stored and is readily available unless it is overwritten by the next cut or copy command.</p>
    <br>
    <p>Below you will see the keys that are used to do the cut shortcut function</p>
    <img src="images/keyboardshortcutcut.png" alt="Cut Shortcut Key" />

    <h2>COPY</h2>

    <p>The copy command is used as stated. It copies the text or images from the screen that you have selected and strores it.
    <br>Also until it is overwritten by the next cut or copy command.</p>
    <br>
    <p>In the image below you will see the keys that are used to do the copy shortcut function.</p>
    <img src="images/keyboardshortcutcopy.png" alt="Copy Shortcut Key" />

    <h2>PASTE</h2>

    <p>The paste command is used to place the information whether it be an image or text that you have stored on your
    <br>virtual clipboard in the location that you have placed your cursor mouse.</p>
    <p>Below in the image you will see the third and final funtction shortcut key which is used to do the paste shortcut function</p>

Answer 1

我不确定你是否在讨论添加的h3元素默认边距，但如果是这种情况，只需在h3元素中添加一个id，并将以下规则添加到css中。在

<h3 id="remove-default-margin">Design, Develop, Dream</h3>

<style>
    #remove-default-margin{
        margin-bottom: 0;
    }
</style>
