Stylesheet language
Sass is a Cascading Style Sheets (CSS) metalanguage. It is a scripting language that is interpreted into CSS. SassScript is the scripting language itself. Sass consists of two syntaxes. The original syntax, called "the indented syntax" uses a syntax similar to Haml.[3] It uses indentation to separate code blocks and newline characters to separate rules. The newer syntax, "SCSS" uses block formatting like that of CSS. It uses braces to denote code blocks and semicolons to separate lines within a block. The indented syntax and SCSS files are traditionally given the extensions .sass and .scss respectively.

Depending on operating system and browser, default form elements can look okay or horribly disfigured. While Formalize is primarily a CSS framework, it does rely on a bit of JavaScript to bridge the gap in HTML5 support for older browsers.
http://jsbin.com/welcome/1/edit
JS Bin is a webapp specifically designed to help JavaScript and CSS folk test snippets of code, within some context, and debug the code collaboratively.
JS Bin allows you to edit and test JavaScript and HTML (reloading the URL also maintains the state of your code - new tabs doesn’t). Once you’re happy you can save, and send the URL to a peer for review or help. They can then make further changes saving anew if required.
