    back then I had a discussion with Toby about the two very long diagrams at model structure on simplicial presheaves.

    I didn’t use to mind that they stretched way across the screen ,as that is what the scrollbar of the browser window is for. But now that they wildly overlap with the floating table of contents, it’s a mess.

    I guess that means one should put these diagrams into their own scrollbar boxes. I think there is a command for that, but I forget which one. Does anyone know?

    I put in some code that, in theory, ought to work. Unfortunately, it breaks something. I will leave it up for a moment, in case anybody wants to look at it, while I test on the Sandbox.

    OK, the bug here is this: I have to change all of the &s (which normally the parser is smart enough to realise are iTeX &s and not XHTML &s) into &s to make it work.

    So, to sum up, here is what you must do to put something into its own little horizontal scrollbar box:

    1. Add <div style="overflow:auto" markdown="1"> at the top of it.
    2. Add </div> at the bottom of it.
    3. Change any & in it (other than any & which is part of an XHTML character entity reference) to &amp; (which, by the way, is an example of an XHTML character entity reference).

    I would regard that (3) is necessary to be a bug. (It ought to be taken care of automatically as part of the markdown="1" business.) Fortunately it is harmless in this sense: to remove the horizontal scrollbox, you only have to undo (1) and (2); you do not have to undo (3).

    Incidentally, one might argue that all displayed math should automatically be placed in a horizontal scrollbox like this. (I don’t mean that we should do it by hand every time but that Instiki should do it for us as part of the CSS for displayed iTeX.) The scrollbar doesn’t show up unless it is needed (at least not on my browser, and I think that the meaning of setting overflow to auto is precisely that it should show up if and only if it is needed), so we usually wouldn’t notice this. But when we do, it would be handy.

    Thanks, Toby!! Great.
