The Benefits of Using SCSS Over CSS
Cascading Style Sheets (CSS) have been a critical part of web plan for numerous years, empowering designers to control the design and format of web pages. However, as web pages develop more complexity and size, managing large CSS files can end up being challenging and lead to code duplication, maintainability issues, and diminished efficiency.
This is typically where SCSS comes to the rescue. SCSS, which stands for "Sassy CSS," is a prevalent expansion of CSS that provides a range of capable features to make strides tin the development process and make styling more maintainable and efficient.
What is SCSS?
SCSS or Sassy Cascading Style Sheets is a more advanced and evolved variant of the CSS language. It basically extends the CSS with additional features like variables, nesting, mixins and more.
SCSS allows you to use programming constructs-like variables and functions to make the CSS more efficient and maintainable. SCSS provides a way to organize and structure your stylesheets better which could prove to be useful for bigger/larger projects.
SCSS files are generally processed by a preprocessor like Sass- Syntactically Awesome Style Sheets- which basically converts SCSS code into a CSS for the browsers to interpret. This entire process basically allows the developers to write the code in SCSS syntax and then compile it into CSS before the deployment.
Understanding CSS
CSS or Cascading Style Sheets is a style sheet language which is used to describe the presentation of a written document in HTML or XML. CSS typically describes how elements should be rendered on screen, in print or in media.
CSS empowers the web designers to control the layout, appearance, and formatting of the HTML elements. By utilizing CSS, you can specify properties such as colours, fonts, margins, padding, positioning and more, further allowing a more precise control over the overall visual presentation of the web page.
Features of SCSS
- Variables- SCSS allows you to define variables to store reusable values such as colors, font sizes or spacing. This feature allows you to maintain consistency throughout your stylesheets and update values across the different elements.
- Nesting- SCSS allows the nesting of CSS rules within one another, allowing the mirroring of the structure of the HTML. This helps in improving the readability and maintainability by organizing the relatable sheets together.
- Mixins- Mixins are known to be the reusable blocks of CSS which can be included in multiple roles. They allow you to define the complex styles once and then apply them wherever it is needed.
- Partials- SCSS equips you with the possibility of breaking your stylesheets into smaller, modular files called partials. These partials can then be included in other SCSS files, making it efficient and easy to manage large projects and encourage code reuse.
- Inheritance- SCSS also supports inheritance by utilizing the “@extend” derivative by basically allowing one CSS class to inherit styles from another. This feature helps in creating cleaner and organized code by reducing duplication of styles.
- Operators- SCSS also includes the support for the mathematical operators, such as- +, -, /, *- further allowing you to perform calculations directly in your stylesheet.
- Control Directives- SCSS also includes control directives like- @if, @else, and @for- which basically enables the conditional logic and looping in your stylesheets.
- Functions- SCSS also allows you to define custom functions using the @function directive. The functions can help you accept arguments and return values, providing great flexibility.
In this blog, we'll explore the advantages of using SCSS over conventional CSS.
Benefits of using SCSS over Conventional CSS
1. Nesting
One of the foremost advantages of using SCSS is the ability to nest selectors, which mirrors the HTML structure. This feature helps to organize styles more logically and intuitively, making the code simpler to understand and keep up.
Rather than composing separate CSS rules for each component, you'll be able to nest them inside their parent components, lessening repetition and upgrading code clarity.
// Conventional CSS
.holder {
background-color: #f2f2f2;
}
.holder h1 {
font-size: 24px;
}
// SCSS
.holder {
background-color: #f2f2f2;
h1 {
font-size: 24px;
}
}2. Variables
SCSS permits you to define variables, which can store colors, text sizes, or any other value you wish to reuse all through your stylesheet.
This feature promotes consistency and makes it simple to upgrade different components all at once by modifying a single variable. As a result, SCSS promotes a more systematic and streamlined approach to styling.
// SCSS
$primary-color: #007bff;
$link-color: $primary-color;
.button {
background-color: $primary-color;
}
a {
color: $link-color;
}3. Mixins
Mixins are reusable blocks of code that can be included in numerous selectors, comparative to functions in programming. They are unimaginably valuable for applying styles that are used habitually, decreasing code duplication, and advancing maintainability.
// SCSS
@mixin button-style {
background-color: #007bff;
color: #fff;
cushioning: 10px 20px;
border: none;
}
.button {
@incorporate button-style;
}
.submit-button {
@incorporate button-style;
font-size: 18px;
}
4. Partials and Import
SCSS supports the concept of partials, which are smaller SCSS files that contain sections of your styles. This approach permits you to break down your styles into manageable pieces, making it simpler to navigate and organize your codebase.
You'll be then able to utilize the @import directive to bring all these partials together into a single primary SCSS file.
// _variables.scss
$primary-color: #007bff;
$secondary-color: #6c757d;
// main.scss
@import 'variables';
@import 'buttons';
@import 'forms';5. Inheritance
SCSS bolsters the concept of inheritance, where one selector can acquire styles from another. This feature enables you to make a base set of styles and after that extend or adjust them for specific elements.
Inheritance diminishes the need to repeat styles and fosters a more modular and efficient coding approach.
// SCSS
.message {
border: 1px strong #ccc;
cushioning: 10px;
}
.success-message {
@extend .message;
color: green;
}
.error-message {
@extend .message;
color: red;
}6. Math Operations
SCSS introduces math operations, allowing you to perform calculations on numerical values. This capability can be helpful when specifying dynamic sizes, positioning, or other styles that depend on calculated values.
// SCSS
.container {
width: 100%;
max-width: 1200px;
}
.column {
width: 50% - 20px;
margin-right: 20px;
}

Conclusion
In conclusion, SCSS brings a range of effective features that significantly progress the advancement process over conventional CSS. Nesting, variables, mixins, partials, inheritance, and math operations all contribute to more organized, viable, and proficient stylesheets.
As web projects become more complex and demanding, adopting SCSS can help developers write cleaner, DRYer (Don’t repeat Yourself), and more maintainable code, eventually coming about in quicker development and less demanding upkeep.
So, give SCSS a try and enjoy a smoother and more productive web development experience!
