I’ve gotten wraparounds to work. I enclose the exhibit comment code inside a div tag. Here the site (using WP 1.2 for now, and Exhibit 1.1d). The page and site is a a work in progress, I make no guarantees that they’ll be there permanently: https://auntialias.com/about/.
Normally, you get something like this: <!--exhibit-thumbs:1-2-->
What I did was enclose that exhibit-style comment in a div and style the div to float left.
Like so:
<div style="float: left; margin-right: 10px; margin-bottom: 10px"><!--exhibit-thumbs:1-2-->
<!--exhibit-thumbs:3-4--></></></div>
When it comes to the standalone closing tags </>
WordPress added them in. First time I saw it, I took ’em out. And then subsequent tagged items would get garbled. So I’ve left ’em in.
