Help finding a "CSS Maker"

I’ve used a website in the past created by a reddit user here, and I can’t seem to find it anywhere. I can’t find the guy or his sub either.

It was basically a step by step guide to making your own sub and at the end of the steps, it makes all the code for you so that you can copy and paste. Pic colors of background, Text, Upvotes then you click the next step and it helps you with a custom header, and side bar.

Any help you have would be appreciated.

Used on my two subs that I created. Not linking here cause I don’t know if that is allowed or not.

What do you mean by “sub”?
