Today I:

Me: "You wrapped 2 p tags and one div inside a button tag....why?"

Other dude: "What do you mean why?" * in condescending tone

Aaaaaaaaaaaand

I lost my shit.

To make things short. My manager told me I have to try harder to not speak to people in intimidating ways.
In all fairness...mr "associates in programming with 0 css experience" WAS condescending when I asked him why he did what he did.

The little shit earned it. And he will probably think twice about his damned tone when speaking to me.
