should i use bootstrap grid or css grid?
What you use depends upon your needs, workflow, time, budget, project, etc. You’re the best person to make that assessment. Unfortunately it isn’t really something that we can choose for you.
is css grid mobile friendly?
Yes.
These are very broad questions and probably not ones that you’re going to get definitive answers for, or get a lot of responses to.
To get the most out of this forum, please ask specific questions, show us the problem code in a demo (CodePen), and explain the undesirable behaviour vs what you actual want/expect to happen.
