There's a newish CSS feature called hyphens that specifies how you want words to be hyphenated when the text wraps. But if you use it, you're going to need to make sure you're also correctly identifying the language. And to understand why that matters, we need to talk about words and syllables.

I’ve come across people who do not think that CSS is related to internationalisation at all, but if you think about it, internationalisation is more than translating the content on your site into multiple languages and calling it a day.
