If you want to just browse here, go ahead, but we recommend you go install Sass first. Go here if you want to learn how to get everything setup. Preprocessing CSS on its own can be fun, but stylesheets are getting larger, more complex, and harder to maintain.

This is where a preprocessor can help. Sass lets you use features that don't exist in CSS yet like variables, nesting, mixins, inheritance and other nifty goodies that make writing CSS fun again. Once you start tinkering with Sass, it will take your preprocessed Sass file and save it as a normal CSS file that you can use in your website.

The most direct way to make this happen is in your terminal. You'll need to tell Sass which file to build from, and where to output CSS to. For example, running sass input. You can also watch individual files or directories with the --watch flag. The watch flag tells Main variables to watch your source files for changes, and re-compile CSS each time you save your Sass.

If you wanted to watch instead of manually build your input. Variables Think of variables as a way to store information that you want to reuse throughout your stylesheet.

You can store things like colors, font stacks, or any CSS value you think you'll want to reuse. CSS, on the other hand, doesn't.

Be aware that overly nested rules will result in over-qualified CSS that could prove hard to maintain and is generally considered bad practice. This is a great way to organize your CSS and make it more readable.

Partials You can create partial Sass files that contain little snippets of CSS that you can include in other Sass files. This is a great way to modularize your CSS and help keep things easier to maintain. A partial is simply a Sass file named with a leading underscore.

The underscore lets Sass know that the file is only a partial file and that it should not be generated into a CSS file. Sass partials are used with the import directive.

Sass builds on top of the current CSS import but instead of requiring an HTTP request, Sass will take the file that you want to import and combine it with the file you're importing into so you can serve a single CSS file to the web browser.

When you import a file you don't need to include the file extension. Sass is smart and will figure it out for you.

A mixin lets you make groups of CSS declarations that you want to reuse throughout your site. You can even pass in values to make your mixin more flexible. A good use of a mixin is for vendor prefixes. Here's an example for transform.

We've named our mixin transform. After you create your mixin, you can then use it as a CSS declaration starting with include followed by the name of the mixin. Using extend lets you share a set of CSS properties from one selector to another.

It helps keep your Sass very DRY. In our example we're going to create a simple series of messaging for errors, warnings and successes using another feature which goes hand in hand with extend, placeholder classes.

General Variables

A placeholder class is a special type of class that only prints when it is extended, and can help keep your compiled CSS neat and clean. This helps you avoid having to write multiple class names on HTML elements. You can extend most simple CSS selectors in addition to placeholder classes in Sass, but using placeholders is the easiest way to make sure you aren't extending a class that's nested elsewhere in your styles, which can result in unintended selectors in your CSS.

Operators Doing math in your CSS is very helpful. Operations in Sass let us do something like take pixel values and convert them to percentages without much hassle.Memory management is a form of resource management applied to computer essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

Mathematics Subject Classification The current Mathematics Subject Classification (MSC) is a revision of the MSC that has been used by MR and Zbl since Meteor resources. The place to get started with Meteor is the official tutorial..

Once you are familiar with the basics, the Meteor Guide covers intermediate material on how to use Meteor in a larger scale app.. Stack Overflow is the best place to ask (and answer!) technical questions. Be sure to add the meteor tag to your question.

Sass (Syntactically Awesome StyleSheets) Sass is an extension of CSS that adds power and elegance to the basic language. It allows you to use variables, nested rules, mixins, inline imports, and more, all with a fully CSS-compatible helps keep large stylesheets well-organized, and get small stylesheets up and running quickly, particularly with the help of the Compass style library.
