“The art challenges the technology, and the technology inspires the art.”

There is a competition between art and technology. When someone demands creativity with flexibility, then the project size is bound to increase. In bigger projects, developers have to face issues related to formatting, debugging, and maintenance. So technically it will take time and an increase in budget.

So in such a problem, it’s advisable to use a preprocessor to deal with these problems. It has a syntax that will make code writing easier and cleaner for the CSS developer. There are different preprocessors like

Here are a few advantages of Scss. Scss is a newer version of Sass Version 3. Sass and Scss have different syntax.

How Does Scss Help?


  • We can use variables to store values and reuse them wherever needed.
  • A small change in a single value of the variable and the value will change in the whole project.


  • CSS doesn’t support nesting. As the project size gets bigger, it brings a readability problem, and the structure looks shabby.
  • When in Scss, we have to declare parents only one time, and we can write CSS nested.


  • A mixin is a group of properties. Once we create a mixin, we can use it with @include. Whenever we need changes, we just change one value. No need to find that all the time.


  • Functions in Sass are similar to the functions in JavaScript. Just like JavaScript, functions in Sass can accept arguments and return some value. 
  • To create a custom function you need two Sass directives @function and @return. The first creates the function, and the second sends a signal to the value to return to the function.

Partials and Import

  • Partials in Sass are separate files that contain Sass code, which makes our code modular. Using partials, we can have separate Sass files for different components. 
  •  Sass feature “@import” allows you to import another Sass file in the main Scss file. so it’s easy to debug and maintain.


  • When designing a page, one class should have all the styles of another class, including its specific styles; @extend can extend CSS properties from one selector to another, and also write
    specific styles. 
  • The advantage of using extended classes is that it only prints in compiled CSS when it is extended and can help keep your compiled CSS neat and clean.

Ampersand (&) operator

  • We can nest selectors that share the same name, and while compiling the & operator will be replaced by its enclosing selector name.


  • @extend, @mixin, and @import are some of the directives that we have seen above. 
  •  Some directives are similar to JavaScript, such as @if, @else, @for, @while.


Sass accelerates you to write clean, easy, and few lines of the CSS code in a programming construct. If you want to handle bigger projects in an organized way, then we recommend you use Scss in your project. It can perform basic calculations, reuse code using mixins, and create functions. Sass makes maintenance of CSS so much easier in bigger projects. Those features make it so powerful. Sass adds basic programming capabilities to CSS.

    Since I learned it, I’m always using it instead of CSS. It really allows me to keep the code more modular and organised.
    Also some of the color functions like lighten and darken are a life saver.

    I use Visual Studio Code and it has a plugin you can install to watch your sass files and, when you save them, it builds the CSS file(s) automatically for you.
