I am not sure it will work, but it's sufficiently easy to try. Look at the innards of HughesPJ, especially the TextBeside data constructor. Its second parameter is an Int holding the length of the text. Perhaps if you created TextBeside with your HTML markup, but with 0 length field, things would be laid out properly.

Something like:

wrap prepend doc append = zeroText prepend <> doc <> zeroText append zeroText s = textBeside_ (Str s) 0 Empty

Of course you will have to modify the HughesPJ library, because Doc is an abstract data type. Best regards Tomasz
