Two lines today. CSS has come a loooong way... One could argue that the main advantage of CSS is that is a living standard, constantly adding and improving features and seeing a competition between implementations; whereas more traditional technologies are typically mono-vendor and, for one reason or another, have long stagnated.
To be fair, if you wanted to implement it before CSS support, I think you’d have a hard time reaching 1000 lines to do it. 50ish maybe (in JS and HTML).
