关于标题中Header 1的Kerning与Tracking的含义及处理方法问询

Hey there, I’ve put together a straightforward Markdown formatting guide tailored for clear, professional posts—ideal for platforms like Stack Overflow:

1. Headings #

Use number signs (#) to define heading levels. The more # you use, the lower the heading hierarchy:

• # Level 1 Heading → # Level 1 Heading
• ## Level 2 Heading → ## Level 2 Heading
• You can go up to 6 levels total (e.g., ###### Level 6 Heading)

2. Unordered List Items #

Start each list item with a dash (-). Indent nested items with spaces to create hierarchy:

• Main list item
  • Nested sub-item
  • Another nested sub-item

3. Text Emphasis #

Wrap text with asterisks (*) to add emphasis:

• Italicize text: *This is italicized text* → This is italicized text
• Bold text: **This is bolded text** → This is bolded text

4. Code & Commands #

Use backticks (`) for inline code, or three backticks for multi-line code blocks (you can add a language tag for syntax highlighting):

• Inline code snippet: git commit -m "Initial commit"
• Multi-line code block:

function greetUser(name) {
  console.log(`Hello, ${name}!`);
}

5. Quoted Text #

Use a greater-than sign (>) to mark quoted content. Add an extra > for nested quotes:

This is a standard block quote

This is a nested quote inside the first one

6. Links #

Format links as [Display Text](Target URL)—the display text is what readers interact with:
[Your Custom Link Text](https://your-target-url.com) → Your Custom Link Text

7. Images #

Insert images using [Alt Text](Image URL). The alt text describes the image for accessibility (critical for screen readers):
[Descriptive Image Alt Text](https://your-image-url.com/image.jpg) → Descriptive Image Alt Text
