How to structure a Sass project

One of the most useful features of Sass is being able to separate your stylesheets into separate files. You can then use the @import directive to include the source of your individual files into one master stylesheet.

But how should you structure your Sass projects? Is there a standard way of separating out your CSS files?

Basic directory structure

I like to layout my Sass projects like this:

stylesheets/
|
|-- modules/              # Common modules
|   |-- _all.scss         # Include to get all modules
|   |-- _utility.scss     # Module name
|   |-- _colors.scss      # Etc...
|   ...
|
|-- partials/             # Partials
|   |-- _base.sass        # imports for all mixins + global project variables
|   |-- _buttons.scss     # buttons
|   |-- _figures.scss     # figures
|   |-- _grids.scss       # grids
|   |-- _typography.scss  # typography
|   |-- _reset.scss       # reset
|   ...
|
|-- vendor/               # CSS or Sass from other projects
|   |-- _colorpicker.scss
|   |-- _jquery.ui.core.scss
|   ...
|
`-- main.scss            # primary Sass file

Primary stylesheet

This allows me to keep my primary Sass file extremely clean:

// Modules and Variables
@import "partials/base";

// Partials
@import "partials/reset";
@import "partials/typography";
@import "partials/buttons";
@import "partials/figures";
@import "partials/grids";
// ...

// Third-party
@import "vendor/colorpicker";
@import "vendor/jquery.ui.core";

Modules, partials, and vendor

As you can see this divides my project into three basic types of files. Modules, partials, and vendored stylesheets.

The modules directory is reserved for Sass code that doesn't cause Sass to actually output CSS. Things like mixin declarations, functions, and variables.
The partials directory is where the meat of my CSS is constructed. A lot of folks like to break their stylesheets into header, content, sidebar, and footer components (and a few others). As I'm more of a SMACSS guy myself, I like to break things down into much finer categories (typography, buttons, textboxes, selectboxes, etc…).
The vendor directory is for third-party CSS. This is handy when using prepackaged components developed by other people (or for your own components that are maintained in another project). jQuery UI and a color picker are examples of CSS that you might want to place in the vendor directory. As a general rule I make it a point not to modify files in my vendor directory. If I need to make modifications I add those after the vendored files are included in my primary stylesheet. This should make it easy for me to update my third-party stylesheets to more current versions in the future.

Using a base partial

In my partials directory you will also notice that I have a base partial. The purpose of this partial is to load up my Sass environment so that it's easy to construct a stylesheet.
It might look something like this:

// Use Compass ('cause it rocks!)
@import "compass";

// Font weights
$light: 100;
$regular: 400;
$bold: 600;

// Base Font
$base-font-family: sans-serif;
$base-font-weight: $regular;
$base-font-size: 13px;
$base-line-height: 1.4;

// Fixed Font
$fixed-font-family: monospace;
$fixed-font-size: 85%;
$fixed-line-height: $base-line-height;

// Headings
$header-font-weight: $bold;

@import "modules/all";

The base stylesheet sets a couple of global variables and loads up all of my Sass modules. Again modules are not allowed to contain anything that would cause CSS output when importing. Tying all of my variables and modules up into a base partial gives me access to my entire Sass environment whenever I'm setting up a new stylesheet with a single import statement. This allows me to build multiple stylesheets by importing different partials. Multiple stylesheets are handy once a project grows to a certain size.

One step further

At UserVoice we take this pattern one step further. Since we have multiple sub-projects all bundled together in a single Rails app, we bundle each sub-project into a separate top-level directory. Our stylesheet directory looks more like this:

stylesheets/
|
|-- admin/           # Admin sub-project
|   |-- modules/
|   |-- partials/
|   `-- _base.scss
|
|-- account/         # Account sub-project
|   |-- modules/
|   |-- partials/
|   `-- _base.scss
|
|-- site/            # Site sub-project
|   |-- modules/
|   |-- partials/
|   `-- _base.scss
|
|-- vendor/          # CSS or Sass from other projects
|   |-- _colorpicker-1.1.scss
|   |-- _jquery.ui.core-1.9.1.scss
|   ...
|
|-- admin.scss       # Primary stylesheets for each project
|-- account.scss
`-- site.scss

As you can see each sub-project has it's own primary stylesheet, modules, partials, and base. Vendored stylesheets are typically versioned and have their own top-level directory. This is a handy pattern to use on very large Sass projects.

Further exploration

Now that I've laid out my own method for this, you may want to explore how other people have structured their Sass projects. There's actually a lot of variation in what you can do here. And some methods may work better on different projects:

What is Bootstrap?

Bootstrap is a free front-end framework for faster and easier web development
Bootstrap includes HTML and CSS based design templates for typography, forms, buttons, tables, navigation, modals, image carousels and many other, as well as optional JavaScript plugins
Bootstrap also gives you the ability to easily create responsive designs

	What is Responsive Web Design? Responsive web design is about creating web sites which automatically adjust themselves to look good on all devices, from small phones to large desktops.

Bootstrap History

Bootstrap was developed by Mark Otto and Jacob Thornton at Twitter, and released as an open source product in August 2011 on GitHub.
In June 2014 Bootstrap was the No.1 project on GitHub!

Why Use Bootstrap?

Advantages of Bootstrap:

Easy to use: Anybody with just basic knowledge of HTML and CSS can start using Bootstrap
Responsive features: Bootstrap's responsive CSS adjusts to phones, tablets, and desktops
Mobile-first approach: In Bootstrap 3, mobile-first styles are part of the core framework
Browser compatibility: Bootstrap is compatible with all modern browsers (Chrome, Firefox, Internet Explorer, Safari, and Opera)

Where to Get Bootstrap?

There are two ways to start using Bootstrap on your own web site.
You can:

Download Bootstrap from getbootstrap.com
Include Bootstrap from a CDN

Downloading Bootstrap

If you want to download and host Bootstrap yourself, go to getbootstrap.com, and follow the instructions there.

Bootstrap CDN

If you don't want to download and host Bootstrap yourself, you can include it from a CDN (Content Delivery Network).
MaxCDN provide CDN support for Bootstrap's CSS and JavaScript. Also include jQuery:

MaxCDN:

<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>


<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

	One advantage of using the Bootstrap CDN: Many users already have downloaded Bootstrap from MaxCDN when visiting another site. As a result, it will be loaded from cache when they visit your site, which leads to faster loading time. Also, most CDN's will make sure that once a user requests a file from it, it will be served from the server closest to them, which also leads to faster loading time.

Create First Web Page With Bootstrap

1. Add the HTML5 doctype
Bootstrap uses HTML elements and CSS properties that require the HTML5 doctype.
Always include the HTML5 doctype at the beginning of the page, along with the lang attribute and the correct character set:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
</head>
</html>

2. Bootstrap 3 is mobile-first
Bootstrap 3 is designed to be responsive to mobile devices. Mobile-first styles are part of the core framework.
To ensure proper rendering and touch zooming, add the following <meta> tag inside the <head> element:

The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).
The initial-scale=1 part sets the initial zoom level when the page is first loaded by the browser.
3. Containers
Bootstrap also requires a containing element to wrap site contents.
There are two container classes to choose from:

The .container class provides a responsive fixed width container
The .container-fluid class provides a full width container, spanning the entire width of the viewport

Note: Containers are not nestable (you cannot put a container inside another container).

Two Basic Bootstrap Pages

The following example shows the code for a basic Bootstrap page (with a responsive fixed width container):

Example

<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
<h1>My First Bootstrap Page</h1>
<p>This is some text.</p>
</div>

</body>
</html>

Try it Yourself »

The following example shows the code for a basic Bootstrap page (with a full width container):

Example

<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container-fluid">
<h1>My First Bootstrap Page</h1>
<p>This is some text.</p>
</div>

</body>
</html>
</div>
