                I frequently get asked about over-abstracted CSS, and ‘can CSS be too modular’, so I thought I’d publish this anonymised email I received, along with my reply.

I published this email exchange as a full post at csswizardry.com/…/can-css-be-too-modular.

  
## derivative.js
function derivative(f) {
   var h = 0.001;
   return function(x) { return (f(x + h) - f(x - h)) / (2 * h); };
}

console.log(" cos(2) = " + Math.cos(2));
console.log("-sin(2) = " + Math.sin(2));
console.log("(d cos/dx)(2) = " + derivative(Math.cos)(2));

function f(x) { return Math.pow(x, 3) + 2 * x + 1; };
