Change first post style on some threads
 

I would like that mods can change the style of the first post of some threads (not all the threads, we should be able to choose manually on which thread), for example the first post could have another background color.

In fact in some threads the first post is used to summarize some informations.

It is possible?

Yes, it's impossible.

First off all you need install the mod called: First post all page
Then Edit template of this Mod.

Or you can insert variable for first post to template postbit(_legacy)
