SASS (Syntactically Awesome StyleSheets) and SCSS (Sassy CSS) are CSS pre-processors that introduce concepts like variables, mixins, and nesting to make CSS easier to write and more dynamic. SASS is useful for reducing repetition, creating reusable and maintainable stylesheets, and allowing for faster development time. It can be installed with Ruby or Node-based tools like Koala or Gulp. SASS supports both the indented SASS syntax and SCSS syntax, which is more compatible with existing CSS. Key SASS features include variables, mixins, inheritance, operations, and control directives.

This document summarizes Nicholas C. Zakas' presentation on high performance JavaScript. It discusses how the browser UI thread handles both UI updates and JavaScript execution sequentially. Long running JavaScript can cause unresponsive UIs. Techniques to ensure responsive UIs include limiting JavaScript execution time, using timers or web workers to break up processing, reducing repaints and reflows, and grouping style changes. Hardware acceleration and optimizing JavaScript engines have improved performance but responsive UIs still require discipline.
The document discusses Sass, a CSS extension language that adds powerful features like variables, nested rules, mixins, functions and more. It outlines problems with traditional CSS like repetition, maintenance issues and lack of abstraction capabilities. Sass aims to solve these through its additional features that allow for more modular, reusable and maintainable stylesheets. It also introduces Compass, a Sass extension framework and library, and discusses best practices like organization, sprites and separation of concerns.
Sass and Compass Workshop slides discuss:
1. Why Sass and Compass should be used including keeping stylesheets DRY, easier revisions, and creating style frameworks.
2. Sass allows variables, nesting, functions and other features that make CSS more powerful, manageable and reusable.
3. Nesting rules in Sass avoids repetition by nesting selectors within one another like CSS rules.
The document provides a snapshot of various Indian stock market indices as of March 1, 2013.
