Add a Row Block

[melchoyce]

What problem does this address?

The Columns block allows you to do interesting layouts like this, where there are columns of text with different alignments:

But there isn't an equivalent way to handle this vertically:

The best approximation is to add a spacer between the top and bottom text, which is subpar for a number of reasons — the spacer maxes out at 500px tall, it looks bad on mobile, there isn't a way to make the spacer take up a percentage of height, etc.

What is your proposed solution?

Add a row block that acts the same as columns, but vertically instead of horizontally.

I think this is more or less a duplicate of #24473. @melchoyce can you confirm?

[melchoyce]

Honestly can't tell, that seems more specifically about flexbox integration and horizontal grouping?

[kjellr]

Hmm yeah maybe it's a little different. The end result is the same though: blocks arranged horizontally in columns.

I think this can be closed out with the addition of the Row block in 6.0. If folks disagree, happy to reopen <3
