我克隆了 reveal.js 的 git repo,将 js、css、plugin 和 lib 目录复制到/my-home-dir/ 并创建了一个名为 r.html
的示例页面.
在r.html
我有一个 <pre><code></code></pre>
block ,但它没有突出显示......据我所知,这是默认行为。我继续更改 reveal.js 的初始化来帮助解决这个问题,但没有任何改变。 (否则主题和幻灯片都很好)
有什么建议吗?
r.html
的代码如下:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Reveal.js 3 Slide Demo</title>
<link rel="stylesheet" href="css/reveal.min.css">
<link rel="stylesheet" href="css/theme/default.css" id="theme">
<!--Add support for earlier versions of Internet Explorer -->
<!--[if lt IE 9]>
<script src="lib/js/html5shiv.js"></script>
<![endif]-->
</head>
<body>
<!-- Wrap the entire slide show in a div using the "reveal" class. -->
<div class="reveal">
<!-- Wrap all slides in a single "slides" class -->
<div class="slides">
<!-- ALL SLIDES GO HERE -->
<!-- Each section element contains an individual slide -->
<section>
This is my code
<pre><code>
System.out.println("What is this?");
String p = "this is p";
</code></pre>
</section>
</div>
</div>
<script src="lib/js/head.min.js"></script>
<script src="js/reveal.min.js"></script>
<script>
// Required, even if empty.
Reveal.initialize({
dependencies: [
// Cross-browser shim that fully implements classList - https://github.com/eligrey/classList.js/
{ src: 'lib/js/classList.js', condition: function() { return !document.body.classList; } },
// Interpret Markdown in <section> elements
{ src: 'plugin/markdown/marked.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
{ src: 'plugin/markdown/markdown.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
// Syntax highlight for <code> elements

// Zoom in and out with Alt+click

// Speaker notes
{ src: 'plugin/notes/notes.js', async: true, condition: function() { return !!document.body.classList; } }
]
});
</script>
</body>
</html>

最佳答案
正如您已经发现的,您需要加载一个带有突出显示样式的 CSS 文件。这可以是包含在 Reveal.js 发行版中的 zenburn.css
或 other CSS file由 Highlight.js 支持:
<!-- For syntax highlighting -->
<link rel="stylesheet" href="lib/css/zenburn.css">
