## 标题锚点
|
||
|
||
标题会自动应用锚点。
|
||
|
||
### 自定义锚点
|
||
|
||
要为标题指定自定义锚点而不是使用自动生成的锚点，请向标题添加后缀：
|
||
|
||
```md
|
||
# 使用自定义锚点 {#my-anchor}
|
||
```
|
||
|
||
这允许将标题链接为 `#my-anchor`，而不是默认的 `#使用自定义锚点`。
|
||
|
||
## 链接
|
||
|
||
内部和外部链接都会被特殊处理。
|
||
|
||
主题默认对每个 md 文件自动生成一个新的 链接，并保存在对应的 md 文件的 frontmatter 的 `permalink` 中。
|
||
你可以随时修改它们。你也可以通过 `theme.autoFrontmatter` 选项来禁用这个功能，这时会恢复为 VuePress 的默认行为。
|
||
|
||
### 内部链接
|
||
|
||
有三种方式来使用内部链接：
|
||
|
||
- 使用 生成的 `permalink` 作为内部链接的目标。
|
||
- 使用 md 文件的相对路径作为内部链接的目标。
|
||
- 使用 md 文件的绝对路径作为内部链接的目标， 绝对路径 `/` 表示从 `${sourceDir}` 目录开始。
|
||
|
||
```md
|
||
[Markdown](/guide/markdown/)
|
||
|
||
[Markdown](./basic.md)
|
||
```
|
||
|
||
渲染为：
|
||
|
||
[Markdown](/guide/markdown/)
|
||
|
||
[Markdown](./basic.md)
|
||
|
||
### 外部链接
|
||
|
||
外部链接带有 `target="_blank" rel="noreferrer"` ：
|
||
|
||
[VuePress](https://v2.vuepress.vuejs.org/)
|
||
|
||
## Github风格的表格

## 自定义容器
|
||
|
||
自定义容器可以通过它们的类型、标题和内容来定义。
|
||
|
||
### 默认标题
|
||
|
||
**输入：**
|
||
|
||
```md
|
||
::: note

|
||
|
||
::: info
|
||

||
### 自定义标题
|
||
|
||
可以通过在容器的 "type" 之后附加文本来设置自定义标题。
|
||
|
||
**输入：**
|
||
|
||
````md
|
||
::: caution STOP
|
||
危险区域，请勿继续

## GitHub 风格的警报
|
||
|
||
主题 同样支持以标注的方式渲染 [GitHub 风格的警报](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#alerts)。它们和[自定义容器](#自定义容器)的渲染方式相同。
|
||
|
||
**输入：**
|
||
|
||
```md
|
||
> [!NOTE]
|
||
> 强调用户在快速浏览文档时也不应忽略的重要信息。
|
||
|
||
> [!TIP]
|
||
> 有助于用户更顺利达成目标的建议性信息。
|
||
|
||
> [!IMPORTANT]
|
||

|
||
|
||

When $a \ne 0$, there are two solutions to $(ax^2 + bx + c = 0)$ and they are
|
||
$$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$
|
||
|
||
**Maxwell's equations:**

|
||

|
||
| $\nabla \cdot \vec{\mathbf{B}} = 0$ | divergence of $\vec{\mathbf{B}}$ is zero |
|
||
| $\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} = \vec{\mathbf{0}}$ | curl of $\vec{\mathbf{E}}$ is proportional to the rate of change of $\vec{\mathbf{B}}$ |
|
||
| $\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} = \frac{4\pi}{c}\vec{\mathbf{j}} \nabla \cdot \vec{\mathbf{E}} = 4 \pi \rho$ | _wha?_ |

## 属性支持
|
||
|
||
你可以使用特殊标记为 Markdown 元素添加属性。
|
||
|
||
**为图片添加属性：**
|
||
|
||
这将为图片添加 一个 名为 `full-width` 的 class 属性，以及一个 `width` 属性，值为 `100%`。
|
||
|
||
```md
|
||
{.full-width width="100%"}
|
||
```
|
||
|
||
同时也支持其他属性:
|
||
|
||
```md
|
||
一个包含文字的段落。 {#p .a .b align=center customize-attr="content with spaces"}
|
||
```
|
||
|
||
这将被渲染为：
|
||
|
||
```html
|
||
<p id="p" class="a b" align="center" customize-attr="content with spaces">
|
||
一个包含文字的段落。
|
||
</p>
|
||
```
|
||
|
||
