About <div> in Portfolio Project Page

Hi,

I have just started the Portfolio project and I wonder if my grid layout logic is good?

Basicaly I pile up “jumbotron” bootstraps one on top of the over. And then I willc reate separate col-sm-4 columns.

However I wonder if I am doing right?

This question is best added to “help” rather than Project Feedback which is really for completed projects.
The 2nd container & jumbotron don’t have closing div tags.
Your plan seems fine. Try it and ask for help if you get stuck.
