News Homepage with Bootstrap and some custom CSS

So It's my first time using Bootstrap after a year and half writing only vanilla CSS, on one hand I see it as a great workflow and It's concept is great on the other hand I got annoyed every time I had to override things so It looks like you can't build stuff with Bootstrap only, and considering how small and simple this project is I don't see myself using it on complicated projects, however It will be very useful to build some ui components quickly, I would like to get comfortable with it at least, so any feedback or resources will help so much, thank you.
