Sass not only enhances CSS capabilities with variables and nesting but also introduces advanced functions and operations that allow calculations and transformations directly in your style sheets. These features boost the efficiency and flexibility of CSS development.

Operations in Sass

Sass allows mathematical and logical operations, making it easier to manipulate values and create dynamic styles.

Mathematical Operations

In Sass, you can perform arithmetic operations like addition, subtraction, multiplication, and division.

Defining Custom Functions

In addition to built-in functions, you can define your own functions in Sass using the @function directive. This allows you to create custom logic that you can reuse throughout your project.

Conclusion

Functions and operations in Sass extend CSS capabilities, allowing calculations, color manipulations, and other processes directly in your style sheets. These features not only enhance the flexibility of your development but also promote cleaner and more maintainable code. In the next chapter, we will explore control flow in Sass, which will enable you to add conditional logic and loops in your CSS.
