Is it ok / legal / allowed to copy some of the styles from stackoverflow / serverfault / etc. for use in a stack app?
Have a look to Trademark guidance.
Design of Your Product
- Do not copy the look and feel of our products.
and quoting Joel answering a previous question:
Just be reasonable. Trademark law is based on the principle of not confusing "the reasonable person" as to the origin of goods and services.
So, i don't think it is a good idea to copy StackOverflow's CSS for your apps.
2I assume something like StackTack falls under the "reasonable person" argument? Or StackTack is fine since they are just pulling data verbatim? stackapps.com/questions/518/… Jul 29, 2010 at 12:52
1@mlaw - you should use the '@' notation in a comment (like Kevin and I did) to ensure that an addressed commenter get's notified about your follow up question (e.g. you seem to be asking @Kevin here specifically ;) - otherwise only the original posters of answers/questions (e.g. systempuntoout here) will get this notification.

@Steffen thanks. Since I can't edit a comment, I guess I'll have to re-post that one for Kevin to get the notification? Jul 29, 2010 at 14:11
@Kevin please see the second comment. Jul 29, 2010 at 14:12
@mlaw - StackTack doesn't copy our L&F verbatim, and also can be distinguished from SO by a reasonable person. Jul 29, 2010 at 20:34
