哈喽 MonchiLin！欢迎你加入简中文档翻译的团队，感谢你对这篇 on-demand-rendering.mdx 文档翻译投入的时间和精力。

我在建议中标注了几处需要修改的部分，多数是关于链接锚点的，可以在查看后应用修改。另外我还注意到和源文档不同的一处标点（位于第 99 行的：），以及一处主动添加代码注释的文本（位于第 248 行的 body），因为我觉得利于阅读所以我选择保留了。

[MonchiLin]

@Nin3lee 非常感谢你的审核和指正, 之前确实不了解锚点的转换规则

[Nin3lee]

LGTM! 💜 Thanks again for your effort and time to contribute.

Maybe other maintainers will have their own suggestions.
