Flexbox- What am I doing Wrong?

I’m trying to use only Flexbox on my portfolio site. However, I’m new to it. (Previously, you guys were very nice to help me with Bootstrap.

In this project, I’m not sure why I can’t center my name in the middle of the black box and center the titles in the black box while having the lined up next to each other. I have the code that I think should work in here. Can someone please tell me what I am doing wrong? I learned basic flexbox with Flexbox Froggy.

Thanks.

Thanks. I did discover that some of the code you gave me doesn’t do anything. I’m going to try do do some research and find out why. It’s similar to the issue I was having. However, it did fix the placement of my name, so step one complete.

I really appreciate your help. You seem to help me on a lot of my projects.
