(Original) Background: Because I like to take some notes in the blog garden recently, I found that the content of the notes is not very convenient to read, and there is a lack of a content directory, so I will do it.
I checked some materials and found that they were not detailed enough, so I wrote one myself. If it is troublesome, just write the anchor point and the return to the top together.
The following code can be imported through the file in the "Settings" of the blog garden.
