The Sass built-in math module: an introduction with code examples

The SASS built-in math module is a set of functions for performing mathematical operations within Sass. It allows you to perform basic mathematical operations such as addition, subtraction, multiplication, and division, as well as more complex operations like finding the minimum or maximum value, calculating the square root, or performing modulo operations.

In this blog post, we will explore the SASS built-in math module and see how it can be used with code examples.

Basic Mathematical Operations

The SASS built-in math module provides functions for performing basic mathematical operations, such as addition, subtraction, multiplication, and division. Here's an example:

$width: 200px;
$height: 100px;

.container {
  width: $width;
  height: $height;
  padding: $width / 4;
}

In this example, the width and height variables are assigned values, and the padding property for the .container class is set to a quarter of the width value.

More Complex Mathematical Operations

The SASS built-in math module also provides functions for performing more complex mathematical operations, such as finding the minimum or maximum value, calculating the square root, or performing modulo operations. Here's an example:

$value1: 25;
$value2: 50;

.element {
  font-size: max($value1, $value2);
}

In this example, the font-size property for the .element class is set to the maximum value between $value1 and $value2.

Working with Units

The SASS built-in math module also provides functions for working with units, such as converting units or performing mathematical operations with units. Here's an example:

$value1: 25px;
$value2: 1em;

.element {
  margin: $value1 + $value2;
}

In this example, the margin property for the .element class is set to the sum of $value1 and $value2, which are both values with units.

Conclusion

The SASS built-in math module provides a powerful tool for performing mathematical operations within Sass. Whether you are working with basic mathematical operations, more complex operations, or units, the built-in math module has you covered. By using the functions provided, you can simplify and streamline your stylesheet, making it easier to maintain and manage. Whether you are a seasoned Sass user or just getting started, the built-in math module is an essential tool for any Sass developer.
