China DOS Union

We know that when replying, we can use Discuz code to change the font color of the post to black background and white text. Then we might as well simply change the default interface color of the forum to black background and white text. First, this can reflect the DOS characteristics of the DOS forum. Second, it is easy on the eyes. Although the forum already has a command-line interface with black background and white text, after all, it is used infrequently. I know that Discuz 6.0 now has the function for each user to choose the various different style interfaces prepared in advance, and one of the "Deep and Eternal" styles is basically black background and white text. I wonder if Discuz 2.5 has this function.

You can try "Black and White World", but it's not perfect.
