我出于非传统原因而追求 HTML。我认为它在学术论文中提供了比 MS Word 或 LaTeX 更合适的 Canvas ，因为它为作者提供了更好的交流方式。我正在尝试编写一种可用于符合传统 APA 6 指南的学术论文的格式。
我想使用 index.html 文件或 style.css(我不知道哪个更合适)使页面看起来像一张 8.5 宽的纸(确切尺寸并不重要)，而不是完整的浅灰色背景上的宽度。这是在 wordpress 二十十二个主题中完成的，如下所示:
我如何通过更改 index.html 文件(如下所示)来复制这种感觉，或者我可能需要向 style.css 文件中添加一些内容？具体来说，我怎样才能在彩色背景上加上“页面”？
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>title</title>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.
</body>
</html>
我尝试从 twenty-12 窃取但无法理解，因为这些文件是 php 并且我不知道 style.scc 文件中的内容。
最佳答案
这是一个简单的例子……具体的规则很容易改变，但应该给你一个想法。基本上，您在正文 (div.container) 的子元素上设置小于 100% 的宽度。然后，将 margin-left 和 margin-right 值设置为 auto 以使其水平居中。 height:400px 和 margin-top 和 margin-bottom 设置为 1em 是任意值。您的页面内容只需要构建在 div.container 元素内...您的人造页面。
CSS
body {
background: #efefef;
}
.container {
width: 90%;
height: 400px;
margin: 1em auto;
background: #FFF;
}
.container p {
padding: 1em;
}
HTML
<body>
<div class="container">
