What is the difference between the first-class title and the second-class title of a periodical?

1, the first-level title refers to the titles with serial numbers 1 and 1, which is also the largest title. This is a single line without punctuation.

2. The secondary title refers to the title with serial number (1), which is generally the same as the font size of the text, single line and no punctuation;

3. The third-level title refers to the title with serial number 1. Generally speaking, it is the same size and font as the text;

The main purpose of setting the subtitle is to clearly show the level of the article. Some words generally show the central content of this level; Some also use numbers, which only indicate the order of "one, two, three", and play the role of connecting the preceding with the following. It should be noted that no matter which form it takes, it should be closely related to the content of the hierarchy and the close relationship between the preceding and the following.
