Yeah CSS is a complete nightmare. Nothing works and you never know why. The only thing you can do is to randomly change attruibutes randomly until something happens. I remember working on a simple website and i had to do a gradient banner. The gradient was relatively simple but the true challenge was making it stretch edge to edge. No matter what i did there was always a little bit of padding or the layout was completely off. I don't even remember how i solved it.
I don't know how things work where your live, but I'm willing to bet my right hand that there is not a single person in my school that knows what to do in case of a seizure.
I could say the same about reddit except for the "enjoy" part. I imagine that in a while people will give up on finding alternatives and go back to reddit. Unless reddit keeps doing more stupid stuff it's not going away anytime soon.
