TLDR

To cross-reference in Markdown, combine the link syntax []() with an ID attribute. For cases where Markdown extensions aren't supported, define anchors using HTML directly.

Creating anchor with HTML:

<h2 id="target-section">Target Section</h2> <!-- HTML: Still functional in a Markdown world! -->

Linking to the anchor:

[Jump to Target Section](#target-section)

Keep the id attribute consistent with your corresponding link. This method provides more universality and convenience for cross-referencing in Markdown contexts.

HTML and Markdown: A harmonious blend

HTML tags can leverage Markdown's simplicity and elegance to introduce more functionality. Here's how;

Named anchors with HTML

<h3><a name="section-name"></a>Section Name</h3> <!-- HTML: of the old, by the old but for the new (Markdown)! -->
[Go to Section Name](#section-name)

Even though XHTML deprecated the name attribute, it still receives wide support and integrates perfectly within HTML5. As such, it remains a sensible and safe choice for anchor creation.

Markdown flavors: Not every platform has the same taste

Different platforms offer unique syntax for Markdown anchors, enhancing cross-referencing:

GitHub auto-generated anchors

[Header Title](#header-title)

GitHub uses header titles to automate anchor generation. GitHub flavored Markdown anyone? 😄

Manual anchors with Markdown Extra

## Heading {#custom-id}

With Markdown Extra, you have the luxury of manually setting anchor IDs. Wow, control freaks rejoice!

Bitbucket unique anchor patterns

[Title](#markdown-header-title-with-dashes) <!-- Bitbucket: Buckets of anchors! -->

For the exact anchor patterns in Bitbucket, check your Markdown source.

When using anchors, lookout for common pitfalls:

Avoid global variables

Avoid using id attributes in scripting to prevent creation of unintended global variables. 🤓Syntax matters in the "id" entity!

Case sensitivity

Remember, references are case-sensitive. Consistency between anchor definitions and links is key. 😎Case closed!

Special characters

When depending on auto-generated ones, remove or replace special characters for clean and functional anchors. 💪Like Hulk, smash those unwanted characters!

Increasing readability: The key to reader retention

Use meaningful names

Make your anchor names intuitive and descriptive:

[See the User Guide](#user-guide) <!-- User Guide: Reading material for the digital traveler -->

Organize sections logically

Like a city map, arrange sections in a reader-friendly pattern:

| Chapter | Anchor Tag | |---------|------------| | Intro | #intro | | Setup | #setup | | Tips | #pro-tips |

Provide clear summaries

Avoid fillers, keep your summaries concise and to the point:
