How to promote a project hosted on GitHub?

Question

css

Hi all!
I have a project that, in my opinion, is quite interesting and useful for beginners and web designers. It has a lot of interesting and useful features. I know that about fifty sites are already using it, but that's it. Site traffic is also growing rapidly, but jumps, from time to time. I tried to promote it in social networks, but the result so far is also not very good. Spamming in all publics is also not a hunt, and it will not bring any benefit to the project.
Placing on cdnjs requires more than 200 stars and / or 800 downloads per month, but I still don’t understand how to place on jsdelivr. Now I'm trying to stick it into npm, learning node.js and gulp along the way. For a startup, of course, this is normal, but it’s still difficult to promote a project alone. Tell me how you can interest users and find assistants? Where is it better to share a project without harming other people's publics and the project? Maybe there are live chats/forums?
If anyone is interested here is the project https://github.com/madeas/box-shadows.css

> Where is the best place to share a project without harming other people's publics and the project?
On reddit in profile subreddits. For a Russian-speaking audience - on Habré (if you write a quality article).

Answer 2

I once published on codeproject.com and the audience there is much more kind than on Habré, although it is smaller, but judging by Alexa Informitru, this is one of the most popular sites about programming in India.
