1.1 Classification of tags
1.1.1 Classification by subject:
1. Tags with subject : Such as 240cb830ca84ebaabbd07850110b414ddatae6e38b3c62e8df885fe2e3986461aa63
2. Label without subject: such as 076402276aae5dbec7f672f8f4e5cc81 Line break label
Determine whether a table needs to be Subject, you can think about whether the tag needs to encapsulate data. If it needs to encapsulate data, then the tag must have a body. If it does not need to encapsulate data, then there is no need to have a body .
2.1.2 Classification by line :
1. If the content of a label needs to occupy an independent line, we call it a block label. For example: 4a249f0d628e2318394fd9b75b4636b1Title tag
2. If a tag does not need to occupy a separate line, we call it an inline tag. For example: 240cb830ca84ebaabbd07850110b414dFont tag
