下面第四个
最近抖音莫名很火的一个爱心❤️
实现的方法不尽相同，重要的是心意而不是代码本身
前三种用Python来实现，最后一种较为复杂，是用HTML来实现，是笔者搜集而来

笔者能力有限，文章不免疏漏，还请博友们及时指正
哎非说我文章质量不行没法发出来，我下面复制点东西（大家直接忽略）
下面也是Mkdocs的Blog相关的问题，感兴趣可以去看我主页关于Mkdocs的介绍
Hey there! You're looking at our new blog, built with the brand new built-in blog plugin. With this plugin, you can easily build a blog alongside your documentation or standalone.
Proper support for blogging, as requested by many users over the past few years, was something that was desperately missing from Material for MkDocs' feature set. While everybody agreed that blogging support was a blind spot, it was not obvious whether MkDocs could be extended in a way to allow for blogging as we know it from Jekyll and friends. The built-in blog plugin proves that it is, after all, possible to build a blogging engine on top of MkDocs, in order to create a technical blog alongside your documentation, or as the main thing.
