How to Declare and Use SASS Variables Across Multiple Files?

Utilizing SASS Variables Across Multiple Files

In a project with multiple CSS files, managing project-wide style variables can be crucial. SASS provides a robust solution for this through the use of variables. This article explores how to declare and use variables across multiple SASS files, ensuring consistency and maintainability.

Declaring Variables in a Central Location

Consider having a single file, such as _master.scss, where all SASS variable definitions are stored. This file acts as a central repository for variables, as seen in the following example:

// _master.scss 

$accent: #6D87A7;           
$error: #811702;
$warning: #F9E055;
$valid: #038144;

Including Variables in Other Files

To include these variables in other CSS files, use the @import directive in the following manner:

// MyStylesheet.scss

@import "_master.scss";

// Use variables defined in _master.scss
.container {
  color: $accent;
}

In this example, the MyStylesheet.scss file imports the _master.scss file, gaining access to the variables declared within it.

Alternate Method: Modular Approach

Alternatively, you can employ a modular approach by creating a separate folder for utility files. Within a file named _variables.scss, declare your variables. Then, in your main SASS file (e.g., style.scss), import all your other SASS files and begin with the _variables.scss file:

// Utilities
@import "utilities/variables";

// Base Rules
@import "base/normalize";
@import "base/global";

With this approach, variables defined in _variables.scss become accessible throughout the project. Ensure this file is imported before any of the other files that require access to the variables.
