Frequently Asked Questions
What's the difference between CommonMark and GitHub Flavored Markdown?
CommonMark is the standardized specification for Markdown, ensuring consistent parsing across implementations. GitHub Flavored Markdown (GFM) extends CommonMark with additional features like tables, strikethrough text, task lists, and autolinked URLs that are popular on GitHub.
How do I create tables in Markdown?
Use pipes (|) to separate columns and hyphens (-) for the header separator. Example:
| Name | Age | City |
|------|-----|------|
| John | 25 | NYC |
| Jane | 30 | LA |
You can align columns using colons in the separator row: :--- (left), :---: (center), ---: (right).
Can I include HTML in my Markdown?
Most Markdown processors allow HTML tags within Markdown documents. However, the support varies by implementation. For maximum compatibility, stick to standard Markdown syntax when possible, and use HTML only for features not available in Markdown.
How do I add math equations to Markdown?
Math support depends on your Markdown processor. For LaTeX-style math, use single dollar signs for inline math ($x^2$) and double dollar signs for display math ($\frac{1}{2}$). Some processors require specific plugins or configurations to render math equations.
What's the best way to format code in Markdown?
For inline code, wrap text in backticks: `code`. For code blocks, use triple backticks with optional language specification:
```javascript
function hello() {
console.log('Hello, World!');
}
```
This enables syntax highlighting for the specified language.
How can I optimize my Markdown for SEO?
Use proper heading hierarchy (H1 for title, H2 for main sections), include descriptive alt text for images, use meaningful link text instead of 'click here', structure content with clear paragraphs, and include a meta description if your Markdown processor supports frontmatter.
