Testing the Blog System - Sun Changsheng

This is a test post to verify the blog system works correctly with multiple posts.

Testing Different Features

Let me test various markdown features to ensure everything renders properly.

Mathematics

Here's a quadratic equation:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

And some inline math: The sum $\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$ is well-known.

Code Examples

Python code with syntax:

class BlogPost:
    def __init__(self, title, date):
        self.title = title
        self.date = date

    def render(self):
        return f"<h1>{self.title}</h1>"

JavaScript example:

const fetchPosts = async () => {
    const response = await fetch('/api/posts');
    return response.json();
};

Tables

Feature	Status	Notes
Math rendering	✓	KaTeX works
Code blocks	✓	Simple CSS styling
Tables	✓	Native markdown

Lists and Formatting

Bold text and italic text work as expected.

Unordered list: - First item - Second item - Nested item - Another nested item - Third item

Ordered list: 1. Step one 2. Step two 3. Step three

Block Quote

This is a quote block. It should have a left border and different background color to distinguish it from regular text.

Conclusion

This test post demonstrates that all major markdown features are working correctly in the blog system.
