Conditionizr is an intelligent jQuery plugin, that detects the end-users browser and pixel ratio, allowing you to serve specific conditional JavaScript and CSS files they need.

With legacy browsers, we often see Conditionial statements wrapped around our HTML element, so the browser can use the HTML tag relevant to the browser. Conditionizr steps in to take this conditional approach one step further, detecting those IE versions, and adds the relevant class-name to the HTML tag. This means no more conditional statements on the HTML tag.

TypeScript is a language for application-scale JavaScript development. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. Any browser. Any host. Any OS. Open Source.

TypeScript starts from the syntax and semantics that millions of JavaScript developers know today. With TypeScript, you can use existing JavaScript code, incorporate popular JavaScript libraries, and be called from other JavaScript code.

TypeScript compiles to clean, simple JavaScript code which runs on any browser, in Node.js, or in any other ES3-compatible environment.

Fokus uses JavaScript to emphasize anything you select by covering the rest of the page with semi-transparent black.

The library has no dependencies and weighs in at around 3kb. A canvas element is used to paint the cut-out cover. Works in most modern browsers except IE and touch devices.
