### 1.1 Goal of the Tutorial
This tutorial aims to provide you with the best practices for importing and managing partials in SASS/SCSS.

### 1.2 Learning Outcomes
By the end of this tutorial, you'll be able to:
* Import and manage partials in SASS/SCSS effectively.
* Understand and apply best practices when working with SASS/SCSS.

### 1.3 Prerequisites
Before proceeding with this tutorial, you should have a basic understanding of:
* HTML & CSS
* The basics of SASS/SCSS

### 2.1 Importing Partials
To import partials in SASS/SCSS, we use the `@import` directive. This directive takes a filename to import. In SASS/SCSS, a partial is a file named with a leading underscore.

For example, `_reset.scss` would be imported using `@import 'reset';`

### 2.2 Managing Partials
Partials are a great way to modularize your CSS and help keep things easier to maintain. A good practice is to group related functionality into separate partials.

For example, you might have a partial for variables, one for mixins, one for base styles, and so forth.

### 3.1 Basic import
```scss
// _reset.scss
html, body, ul, ol {
    margin: 0;
    padding: 0;
}

// main.scss
@import 'reset'; // This will import the _reset.scss file
```
In the example above, the `_reset.scss` file is imported into `main.scss`. The CSS rules defined in `_reset.scss` will now be available in `main.scss`.

### 3.2 Importing multiple files
```scss
// main.scss
@import 'variables', 'mixins', 'base';
```
In this example, multiple partials are imported into `main.scss`. The order of the imports matters, if your 'base' styles depend on 'variables' and 'mixins', they should be imported first.

### 5.1 Exercise 1
Create a `_variables.scss` partial that defines colors for your site, and import it into your main stylesheet.

### 5.2 Exercise 2
Create a `_mixins.scss` partial that defines a mixin for a media query, and import it into your main stylesheet.

### 5.3 Exercise 3
Create a `_base.scss` partial that applies some of the colors from your `_variables.scss` partial and uses the media query mixin from `_mixins.scss`. Import all of these partials into your main stylesheet.
