Hi there,
lets try this for exampleL
1. Add a Container Block for the section.
2. Insert the Inner Container:
https://docs.generateblocks.com/article/add-inner-container/
3. Se you background and padding. etc.
4. with the Inner Container Block selected, Set its Layout > Flex
For questions 1 and 2:
1. Set its Layout > Flex Wrap -> Wrap
2. Set its Layout > Align Items -> Flex End ( bottom ) icon.
Now inside the inner Conatiner, add 3 x Container Blocks.
Container 1 and Container 2 set there widths to define two columns eg. 30% and 70%
Container 3 its width should be 100% so it forms its own Row.
Now populate container 1 and 2 with your content. You will see that the Align Items -> Flex End ( bottom ) will position the two containers to the bottom.
For question 3, same height columns now require you to set the Sizing > Height to 100% on the container.
