At Tip #2 an example is given of creating a complex layout with columns within columns:
For example, here’s a layout for three main columns (two on top, one below) in which the first column (on the left) includes a layer with four child columns and the second column (on the right) includes a layer with two child columns.
See the link for the image.
To recreate this layout can I simply:
Start with a row containing one column.
Drag in a second column to create two columns in the top layer
Drag in 4 columns into the second layer
Then adjust the width of the first four columns in the second layer so that they add up to 50% percent?
The description sounds to me like the aim is to create two columns side by side, then to add a layer of 4 columns within the left hand column. However, this doesn’t work. I think this is because this would be a child column within a child column.
So it’s not the same layout as the example. The two columns at bottom right won’t go any higher than the bottom edge of the image in the top left column (bench).
How can I recreate the example layout?
NB. I’m using BB in Firefox 81.0.1 (Flatpak) on Debian Buster
