I have an old blog that I’d like to update and then use more in future. To this end, I’d like to convert all the existing posts and visual approach from the Classic Editor to the Block Editor. However, for the life of me I can’t work out how to do this because some things are nested with the old X shortcodes and I can’t see how to do something similar with the Block Editor because these things don’t nest anymore.
Please see here for example of an old post I want to convert: https://tipsunzipped.com/407/use-confluence-to-version-control-office-documents-best-practices
Note that all the blue boxes in this example are built from X shortcodes. The last blue box is inside an ordered list, and it includes both text and an image with its caption.
The problem is, when I try to convert to the Block Editor, the blocks split things up so that the image is no longer inside the blue box, but after it instead (and the final paragraph adopts the tiny caption text style too).
How do I convert these old posts, and how should I do this sort of thing in future with the Block Editor? It doesn’t seem possible to nest things anymore, so how are we supposed to create more advanced panels like this? I’ve tried various advanced block plugins, but none of them seem to do what I want (ideally, I’d have not only a coloured background and mixture of text/lists/images, but also an icon and a title — for warnings, tips, examples and such.)
