This article is a summary of my modification of the guestbook page, which can generate a reverse-order displayed guestbook with the input box above the comment list. The outline is as follows: Create a page template and a comment template, and let the former specify the latter. Modify the data retrieval method in the comment template, and if there is a comment ID, reverse it as well. Finally, adjust the layout so that the comment input box is located above the comment list.
