Are you over-using Child Flex-box Containers? 

That's really smart!! I would have done container 2 without thinking twice. Gonna play around with this.

I’m learning so much!!!❤❤❤

Nice, I will try the 3rd. =)

Nice tutorial and explanation of different scenarios. It does remind though of Sections and Inner sections, doesn't it? Not that there is anything wrong with using Containers as the old sections..! I do hope that there is still less code with Containers and inner containers, compared to the old Sections..etc!

7:14 this is how i have been doing, the first one is also interesting

Another method You can use just one main container and call to action widget and set image to be on right

thanks ❤ , i have question please, in the first container we can use the radius in the parent container , why we should use child container for radius style,!?

Most likely yes. People used to use the inner section to add two columns instead of just adding another column... Unless you need to group things or need to do something exceptionally specific, you really don't need child containers.
