Did you know you could create a bilingual static site that only shows one language at a time and switches on flyover, and all that with just HTML and CSS?
CSS is nice, no doubt. Most people think however it is only useful for web designers and graphics people. I like CSS (even though I'm not very familiar with it), and I consider myself neither web designer nor a graphics expert. I am interested in languages, so when I encounter some technology or gadget, I will also check if this can be useful in connection with languages. CSS can.
