Some time back, I posted an article on basic maths (well, okay, arithmetic) symbols and the correct way to present them in web pages. In the course of it, I mentioned that the <sup> and <sub> tags are the wrong way to give that nice fraction-y look to fractions. By which I mean nicer-looking than "29⁄2", for example. The fraction-slash, being smaller than the forward-slash, gets sort of hidden in the crush between the digits. It's worse in some fonts than others, but not really very pretty in any. Anyway, I mentioned in passing that it is possible to create the same effect with CSS, which won't affect the way a screen reader will present it to the user. Then, somewhat to my shame, I basically said "but I can't be bothered right now."
To be fair to myself, it would have been something of a digression. To be honest with myself, it was bloody lazy. And I'm the bleedin' king, or at least in direct line to the throne, of digressionism; that really shouldn't have been an issue.
So I'll make up for it now, by beginning the piece-proper with… a digression! Yay!
