1, use the text box: the title of the paper cover is too long, and it becomes two lines. You can design the whole cover as a text box and then put the title in this text box. You can control the alignment of the title by adjusting the properties of the text box.
2. Manual adjustment: If you use Word processing software, such as Word, and the title on the cover of the paper is too long and becomes two lines, you can manually select each word in the title and fine-tune it by using the alignment method on the toolbar.
