Thanks for the quick reply!
I am not seeing an option like that. With a lot of random fumbling, I can eventually get a “select parent grid” option. But that provides no information or options regarding the columns. If I select one of the two blocks I have as columns, I can adjust width percentage, but the page looks awful in the browser, with one column (the one on the left containing an image) overlapping the right column. If I select “Edit as HTML”, the block crumbles into an error that needs the code resolved (so I have to back out of the page).
I’ve been using WordPress for 11 years (I even teach it) and have been coding Web sites since 2000 – but thus far, I am not finding GenerateBlocks intuitive. I’m sure I will eventually figure it out.
Anyway, thanks anyway for your quick reply.
