### Markdown vs HTML List Syntax

Source: https://github.com/w3c/html/blob/master/docs/contributing-documentation.md

Illustrates the preferred markdown syntax for defining lists and comparing it with its HTML equivalent. It emphasizes using bikeshed definition list syntax where applicable for clarity and conciseness.

```Markdown
* Use [bikeshed definition list syntax](https://tabatkins.github.io/bikeshed/#markdown) where possible. E.g., prefer:

```
: define term
:: term's definition
```

vs.

```html
<dl>
      <dt>define term</dt>
      <dd>term's definition</dd>
</dl>
```

(unless the `<dl>` needs a class attribute for styling i.e., `<dl class="domintro">`)

```markdown
* unordered list item
```

vs.

```html
<ul>
      <li>unordered list item</li>
</ul>
```

```markdown
1. ordered list item
```
vs.

```html
<ol>
      <li>ordered list item</li>
</ol>
```
```

--------------------------------

### Merging Pull Requests from Forks (Bash)

Source: https://github.com/w3c/html/blob/master/docs/editing-documentation.md

Steps for merging pull requests originating from forks into the master branch. This involves checking out the master branch, applying the pull request, squashing commits, amending the commit message if necessary, and pushing the changes.

```Bash
git checkout master
pr <pull request ID>
git rebase -i origin/master
# Use 'squash' for commits to be combined
# Use 'reword' to update commit messages
git push
```

--------------------------------

### Interactive Rebase for Squashing/Rewording

Source: https://github.com/w3c/html/blob/master/TEAM.md

### HTML Specification Linking Conventions

Source: https://github.com/w3c/html/blob/master/docs/contributing-documentation.md

Defines the standard linking conventions used within the W3C HTML specification for referencing various types of definitions and references. This includes linking to terms, elements, attributes, WebIDL, and normative/informative references.

```APIDOC
Linking Conventions:

- For definitions of standard terms, use `<a>term known to bikeshed</a>`
- For definitions of elements use `<{img}>`
- For definitions of attributes use `<{img/alt}>`
- For WebIDL terms use `{{HTMLImageElement/alt}}`
- For Normative references use `[[!shortname]]` where `shortname` is the W3C "shortname" of the spec
- For informative references use `[[shortname]]`
- Avoid breaking `<a>` (or `<dfn>`) text content across line breaks. E.g., prefer:

```html
here is a
<a>link that is not broken across lines</a>
making it easy to search/replace :)
```

vs.

```html
here is a <a>link that is sadly broken across
lines</a> making it much harder to search/replace
```
```

--------------------------------

### Bash: Rebase, Push, and Merge PR

Source: https://github.com/w3c/html/blob/master/docs/editing-documentation.md

Updates a local branch with the latest master changes, force-pushes it to update the associated pull request, and then merges it into the master branch using a fast-forward only strategy. This function is useful for updating existing PRs.

```bash
mypr () {
  git checkout $1
  git rebase master
  git push origin $1 --force
  git checkout master
  git merge $1 --ff-only
}
```

--------------------------------

### Merging Pull Requests from Branches (Bash)

Source: https://github.com/w3c/html/blob/master/docs/editing-documentation.md

Procedure for merging pull requests from branches within the same repository. It utilizes a specific function (`mypr`) and automatically closes the pull request upon pushing, unlike merging from forks.

```Bash
git checkout master
mypr <pull request ID>
# Squash and reword commits as needed via git rebase -i origin/master
git push
```

--------------------------------

### Protected Content Markers

Source: https://github.com/w3c/html/blob/master/docs/contributing-documentation.md

Explains the convention for identifying and protecting specific parts of the HTML specification content. Protected content is marked using HTML comments to prevent accidental overwrites and requires filing an issue for changes.

```APIDOC
Protected Content:

Parts of the HTML specification are protected to prevent them being overwritten. Protected content is identified using comments, as follows:
`<!-- W3C START - DO NOT OVERWRITE--> protected text <!-- W3C END -->`.

Please do not change these parts of the specification without [filing an issue](https://github.com/w3c/html/issues).
```

--------------------------------

### Bash: Rebase, Push, and Merge PR

Source: https://github.com/w3c/html/blob/master/TEAM.md

This function rebases a local branch onto the master branch, force-pushes it to update the corresponding remote pull request, and then merges the updated branch into master using a fast-forward only strategy. It's designed to keep PRs up-to-date and cleanly merged.

```bash
mypr () {
  git checkout $1
  git rebase master
  git push origin $1 --force
  git checkout master
  git merge $1 --ff-only
}
```

--------------------------------

### Push Changes

Source: https://github.com/w3c/html/blob/master/TEAM.md

```bash
git push
```

--------------------------------

### GitHub User Identification Format

Source: https://github.com/w3c/html/blob/master/docs/contributing-documentation.md

Specifies the format for marking contributors in pull request comments. Use '+' for adding and '-' for removing a GitHub username.

```markdown
+@github_username
```

```markdown
-@github_username
```

--------------------------------

### CSS Styling for Editor

Source: https://github.com/w3c/html/blob/master/SOURCES.html

Defines a CSS rule to set the background color for elements with the class 'editor'. This styling is likely applied to specific parts of the documentation or development interface.

```css
.editor { background-color: skyblue; }
```

--------------------------------

### Amend Last Commit Message

Source: https://github.com/w3c/html/blob/master/TEAM.md
