I need some help with CSS stuff

I'm not sure what is happening but I've been trying to change the text color of my "About me" and "Who I'd like to meet" for a couple of hours now with no avail.
I've been trying to change the color to yellow btw
I've watched like 3 tutorials, and have used atleast 2 google docs
Note: I am using a Chromebook so whenever I inspect the page the scripting is slightly hard to see.
I am also pretty new to CSS and I have trouble understanding things sometime, so it might've just flown by my head.
If anyone could post CSS codes in the comms to change the text color of "About me" and "Who I'd like to meet" that'd be extremely swag/g

Uhh anyways uh gn its 3 am over here lol
