What's the one thing you always need to look-up?

How do you feel about your memory?
To be honest, I don't have the best memory, I always write down the important things or when I can't remember something I'll definitely search for it.

What are the things developers always forget and need to search for?

justify-content: center;

I got a lot of answers regarding CSS/HTML/JS, Python, PHP, Java, Git
