Text-based message book

Although the basic database guest book can be very beautiful and is better managed. However, for those friends who do not have a database space, text-based guestbooks can also be used for personal websites. And as long as we work hard to do it, we can do it well, and it can even be said that it is no worse than a database-based guestbook. Here I introduce a text-based guestbook. You can see its demonstration at the address below: /, it has the following two characteristics:
1. I use different faces to show the messages posted by different people;
2. Each commenter has the function of selecting small icons.
This guest book must consist of the following four files: a file that records the content of the message; a file that records the color of the message text; both files can be created with notepad. File that reflects the message form; file that finally processes the message information. Here are their source codes:
