Article embedded tags

Tips

Place the modified content in the article, such as /source/_posts/foo.md

MD tags

Front-matter

• title: Article title.
• date: Article publication date.
• comment: Whether to disable comments for the article.
• sticky: When set to true, the article will be pinned. If multiple articles are pinned, they will be displayed in reverse chronological order without pagination.
• tags: Article tags.
• cover: Article carousel image (overrides global settings) and article cover image.
• audio: Article background music (overrides global settings). Set to false to disable background music.

Tips

The modified content should be placed within code fences (e.g., ---), like this:

---
title: foo
tags:
  - bar
  - baz
audio: false
---

title: Article Title
date: Article Publication Date
comment: false   # true/false to enable/disable comments for this article
sticky  : true   # Pin the article
tags:
- Article Tag 1
- Article Tag 2
categories:
    - [Computer Science, Linux]
cover: cover.png # Article header and preview image (overrides homepage carousel)
audio:
  - https://music.163.com/song?id=1387098940
audio: false

### Mathematical Formulas (KaTeX)

To add mathematical formulas using [KaTeX](https://katex.org/) in your article, you need to add `math: true` in the Front-matter:

```markdown
---
title: Displaying Mathematical Formulas
math: true
---

Inline formula: $\sqrt {3x-1}+(1+x)^2$

Display as a standalone block:

$$
\begin {array}{c}

\nabla \times \vec {\mathbf {B}} -\, \frac1c\, \frac {\partial\vec {\mathbf {E}}}{\partial t} &
= \frac {4\pi}{c}\vec {\mathbf {j}}    \nabla \cdot \vec {\mathbf {E}} & = 4 \pi \rho \\

\nabla \times \vec {\mathbf {E}}\, +\, \frac1c\, \frac {\partial\vec {\mathbf {B}}}{\partial t} & = \vec {\mathbf {0}} \\

\nabla \cdot \vec {\mathbf {B}} & = 0

\end {array}
$$
```

#### Multiple Choice Questions

For exercises with 1-n options and only one correct option, use the following format:

```markdown
1. Question[]{.gap} {.quiz} - Option - Correct option {.correct}
   {.options}
```

The usage is as follows:

- `1.`: Question number, must be used.
- `[]{.gap}`: Blank space in the question, rendered as a horizontal line (optional).
- `{.correct}`: Correct option in the question.
- `{.options}`: End of the options list.

Example:

```markdown
1. Which of the following options is correct?{.quiz}
  - Option A
  - Option B
  - Option C
  - Option D (correct answer) {.correct}
{.options}
```

### Multiple Choice Questions

Exercise questions with 2 to more options and multiple correct options are formatted as follows:

```markdown
1. Question {.quiz .multi}
  - Option
  - Correct option {.correct}
  - Correct option {.correct}
{.options}
  > - Annotation for option A
  > - Annotation for option B
  > - Annotation for option C
  > {.options}
```

The usage is as follows:

- `1.`: Question number, must be used.
- `{.correct}`: Correct option in the question.
- `{.options}`: End of the options list (use indentation to control).
