使用kramdown，看起来效果不错:

[I want this to link to foo](#foo)
....
....
{: id="foo"}
### Foo are you?

我看到有人提到过

[foo][#foo]
....
#Foo

工作效率很高，但对于除标题外的元素或具有多个单词的其他标题，前者可能是一个很好的选择。

因为在评论中提到了MultiMarkdown作为一个选项。

在MultiMarkdown中，内部链接的语法很简单。

对于文档中的任何标题，只需以这种格式给出标题名称[heading][]以创建内部链接。

Cross-References An oft-requested feature was the ability to have Markdown automatically handle within-document links as easily as it handled external links. To this aim, I added the ability to interpret [Some Text][] as a cross-link, if a header named “Some Text” exists. As an example, [Metadata][] will take you to # Metadata (or any of ## Metadata, ### Metadata, #### Metadata, ##### Metadata, ###### Metadata). Alternatively, you can include an optional label of your choosing to help disambiguate cases where multiple headers have the same title: ### Overview [MultiMarkdownOverview] ## This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers. If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence. In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.

在pandoc中，如果在生成html时使用——toc选项，将生成一个包含到章节的链接的目录，并从章节标题返回到目录。它类似于pandoc编写的其他格式，如LaTeX、rtf、rst等。对于命令

pandoc --toc happiness.txt -o happiness.html

这里有一点降价:

% True Happiness

Introduction
------------

Many have posed the question of true happiness.  In this blog post we propose to
solve it.

First Attempts
--------------

The earliest attempts at attaining true happiness of course aimed at pleasure. 
Soon, though, the downside of pleasure was revealed.

将产生这个作为html的主体:

<h1 class="title">
    True Happiness
</h1>
<div id="TOC">
    <ul>
        <li>
            <a href="#introduction">Introduction</a>
        </li>
        <li>
            <a href="#first-attempts">First Attempts</a>
        </li>
    </ul>
</div>
<div id="introduction">
    <h2>
        <a href="#TOC">Introduction</a>
    </h2>
    <p>
        Many have posed the question of true happiness. In this blog post we propose to solve it.
    </p>
</div>
<div id="first-attempts">
    <h2>
        <a href="#TOC">First Attempts</a>
    </h2>
    <p>
        The earliest attempts at attaining true happiness of course aimed at pleasure. Soon, though, the downside of pleasure was revealed.
    </p>
</div>

在Markdown规范中没有这样的指令，抱歉。

一些额外的事情要记住，如果你曾经在你想导航到的标题中的符号…

# What this is about


------


#### Table of Contents


- [About](#what-this-is-about)

- [⚡ Sunopsis](#9889-tldr)

- [:gear: Grinders](#it-grinds-my-gears)

- [Attribution]


------


## ⚡ TLDR


Words for those short on time or attention.


___


## It Grinds my :gear:s


Here _`:gear:`_ is not something like ⚙ or ⛭


___


## ⛤ Attribution


Probably to much time at a keyboard



[Attribution]: #9956-attribution

．.． 标题字符串中的#、;、&和:之类的内容通常会被忽略/加条纹而不是转义，还可以使用引用样式的链接来简化快速使用。

笔记 GitHub在提交、自述文件等中支持:word:语法，如果对使用'em感兴趣，请参阅gist(来自rxaviers)。 现代浏览器几乎可以在其他任何地方使用十进制或十六进制;来自w3schools的备考单非常方便，特别是如果使用CSS::before或::after带符号的伪元素更符合你的风格。

加分吗?

以防有人想知道标题中的图像和其他链接是如何解析为id的……

- [Imaged](#alt-textbadge__examplehttpsexamplecom-to-somewhere)


## [![Alt Text][badge__example]](https://example.com) To Somewhere


[badge__example]:

  "Eeak a mouse!"

警告

MarkDown渲染因地而异，所以像……

## methodName([options]) => <code>Promise</code>

．.． 在GitHub上将有一个带有id的元素，例如…

id="methodnameoptions--promise"

．.． vanilla sanitation会导致id为…

id="methodnameoptions-codepromisecode"

．.． 这意味着从模板中编写或编译MarkDown文件要么需要针对一种slugifeing方式，要么为各种巧妙的方式添加配置和脚本逻辑，比如清理标题的文本。

是的，markdown确实做到了这一点，但你需要指定名称anchor <a name='xyx'>。

一个完整的例子，

这就创建了链接 (任务)(#任务)

在文档的其他地方，您创建了命名锚(不管它叫什么)。

<a name="tasks">
   my tasks
</a>

注意，你也可以把它环绕在标题上。

<a name="tasks">
### Agile tasks (created by developer)
</a>
