Dabblet is an open-source web application for rapid prototyping of HTML, [7] CSS and JavaScript, with syntax hilighting and inline previewers. [8] The result is saved to a GitHub Gist to allow sharing with others. [9]


The most polyfills target out-of-date browsers, some exist to simply push modern browsers forward a little bit more. Polyfill is a polyfill, which enables the user to recognize the unprefixed versions of several CSS3 properties instead of requiring the developer to write to the vendor prefixes. It reads the page’s stylesheets and replaces any unprefixed properties with their prefixed counterparts. [10]

< link rel = "stylesheet" href = "/css/styles.css" >
< script src = "/path/to/prefixfree.min.js" > </ script >


Prism is a lightweight, robust, elegant syntax highlighting library. It is a spin-off project from Dabblet. The project had 23,000 unique visitors on its first day. WebMonkey is a new post to it. It is used in a big list of websites like A List Apart and Smashing Magazine , Mozilla Developer Network , CSS Tricks, W3C Technical Reports, and Brendan Eich ‘s blog. [6] [11]
