One is to directly use the cover template provided by word20 10. You can find the appropriate or closest cover template under the Insert menu and the leftmost cover item. If you are not satisfied, you can adjust yourself;

The second is to use "insert"-"picture" as the background, and then add a self-designed cover such as a text box;

Third, use PS to directly design the cover on the high-rise building, you can directly draw a picture to make the cover of the printed version, and at the same time generate a JPG file to insert into the word document. To prevent changing the format later, you can use "Insert section break" (not a page break! ) to separate the cover and the text. Good luck.
