Learn the 7-1 Sass Architecture : A Simple Way to Organize Your Stylesheets

Introduction

Have you ever been stuck with messy CSS files, finding it hard to manage styles in big projects? You're not alone! As projects grow, keeping stylesheets organized can become really tricky.

That’s where the 7-1 architecture in Sass (SCSS) comes to the rescue. It’s a smart way to organize your styles, making them easier to scale, maintain, and work on as a team.

In this article, I’ll explain how the 7-1 architecture works, its benefits, and how you can use it too. By the end, you’ll know how to create neat, well-structured stylesheets that are easy to manage.

I used this technique, and it has made a big difference !

What is the 7-1 Architecture?

The 7-1 architecture is a method to organize your Sass (SCSS) files into seven folders and one main file. Each folder has a specific job, which helps keep your styles neat and easy to manage.

You can think of it like a bookshelf, where each folder is a labeled section for a certain type of book (or in this case, styles). This setup makes it simple to find, update, and expand your styles as your project grows.

Why Use the 7-1 Architecture?

The 7-1 architecture has many benefits:

1. Easy to Scale As your project grows, you can add new styles without making the code messy.
2. Clear Organization Each folder focuses on a specific type of style, so it’s easy to find and manage your code.
3. Better Teamwork Teams can quickly understand the code structure, making work faster and with fewer mistakes.
4. Simple Maintenance Fixing issues is quicker because related styles are grouped logically.

For example, if you want to change button styles, you don’t need to search through a big stylesheet. Just go to the components/ folder and edit the button.scss file.

The Folder Structure Explained

Here’s a breakdown of the 7 folders and their roles:

1. abstracts/ : Contains foundational code like variables, functions, mixins, and placeholders. Think of it as the design system of your project. Example files: variables.scss, mixins.scss.
2. base/ : Holds global styles such as resets, typography rules, and base HTML element styles. Example files: reset.scss, typography.scss.
3. components/ : Contains styles for reusable UI components like buttons, cards, and modals. Example files: button.scss, card.scss.
4. layout/ : Manages layout-specific rules such as grids, headers, footers, and navigation. Example files: grid.scss, header.scss.
5. pages/ Focuses on page-specific styles for individual views or routes in your application. Example files: home.scss, about.scss.
6. themes/ Used for alternate styles, like light/dark modes or brand-specific themes. Example files: dark-mode.scss, corporate.scss.
7. vendors/ Includes third-party styles or overrides for external libraries and frameworks. Example files: _bootstrap-overrides.scss.

How to Set Up the 7-1 Architecture in SCSS

1. Create the Folder Structure

Set up the following folder structure in your project to organize your styles

scss/
├── abstracts/
├── base/
├── components/
├── layout/
├── pages/
├── themes/
├── vendors/
└── main.scss        

2. Write Modular SCSS Files

Each file should focus on a specific purpose. For example, keep button-related styles in button.scss and typography styles in typography.scss.

Example (components/_button.scss)

.button {
  background-color: $primary-color;
  padding: 10px 20px;
  border: none;
  border-radius: 4px;
  color: #fff;
  font-size: 16px;
  cursor: pointer;
}        

3. Import Files in main.scss

Use the @import rule in your main.scss file to combine all SCSS files into one. Example (main.scss):

// Import variables and mixins
@import 'abstracts/variables';
@import 'abstracts/mixins';

// Import base styles
@import 'base/reset';
@import 'base/typography';

// Import components
@import 'components/button';
@import 'components/card';

// Import layout
@import 'layout/header';
@import 'layout/footer';

// Import pages
@import 'pages/home';
@import 'pages/about';
        

4. Compile to CSS

Finally, use a Sass compiler to convert your SCSS files into a single CSS file for your project. Popular tools include Dart Sass, node-sass, or build tools like Webpack and Gulp. Example (CLI command):

sass scss/main.scss public/styles.css        

By organizing your SCSS files in this way and compiling them properly, you ensure a maintainable and scalable styling structure for your project!

Conclusion

The 7-1 architecture in Sass is not just a simple file structure; it’s a strategic approach that can significantly streamline your development process and make your stylesheets more scalable and maintainable in the long run. Whether you're working alone or in a team, this methodology helps you stay organized, reduces complexity, and ensures that your styles are easy to manage as your project grows.

By adopting the 7-1 architecture, you’re setting up your project for success, making collaboration smoother and debugging faster. It’s a best practice I highly recommend for any developer looking to organize their styles like a pro.
