Preface Regarding code highlighting in the blog, my earliest approach was modifying blockquote CSS to achieve the display effect of code blocks Later I experimented with introducing Google's code-prettify to implement code highlighting, converting blockquote to pre code Finally, because code highlighting would clear the text background color I set in code snippets , I switched back to the effect of 修改 blockquote 的CSS 来实现 代码段 Now I have enabled the Blogger editor to input pre and code , so I use blockquote to actually represent quotations, quoting the natural language I send to the Agent, which is indeed a scenario I have used a lot in the last few months. I also used the Agent to operate the Blogger API to help me replace blockquote with pre in historical posts Now I am reconsidering the code highlighting issue.
