Hey guess what!
I added a new feature to Publ! It lets you wrap text closely around images that are floated, via a CSS attribute which is pretty widely-supported but kind of annoying to deal with. Which is to say that Publ itself isn’t really doing all that much work here but it was easy to add some plumbing into it to make the browser able to do all the work for you. (So far the only entries on my site using this function are this one and the GRS article which I updated to use it a little bit.)
It’s kind of neat, so please check it out.
