The basic rule of headline writing is to arrange in the middle, the font size should be larger than the text, and the font should be different from the text, with one line above and one line below. If there are many words in the title, it should be arranged line by line, but attention should be paid to the integrity of the meaning after the line goes forward, and it is still required to be centered in the coherent arrangement.

The format of the article subtitle should be close to the title, there should be no blank lines in the middle, there should be dashes in front of the title and the font used should be different from the title. In general, subheadings should start with dashes under the third word of the title.
