I use the CSS because that's how I learned it. 🙂 The standard ( does support <em> and <strong>.

I'm not likely to change, though, for two reasons. I've been doing HTML for hand for a while, so the closer to the old tags, the more likely I am to remember it. 🙂

Secondly, I use it here because of how I learn. I like taking bits of things and changing them – the examples make it clear how you can mix and match.

And a good point with the text-to-speech. I'll have to check; I really don't know. Thanks for pointing that out – if that's the case, I'll revise the guide appropriately.
