Sass is quite popular and tends to be an essential tool for every front-end developer. Sitepoint has already published some introductory articles about this CSS preprocessor language.
In this article, we’ll continue exploring Sass by diving into its operations.
Note: The examples will be based on Ruby Sass. I also suggest you to have a look at Hugo’s article, which discusses Sass-Compatibility.
Assignment Operator
Sass uses the colon (:) operator to define a variable. For instance:
$main-color: lightgray;
Arithmetic Operators
Arithmetic operators are used to perform the standard arithmetic operations.
Here are the arithmetic operators that Sass supports:
Operator Description
+ Addition
– Subtraction
* Multiplication
/ Division
% Remainder
As we’ll see in an upcoming section, the addition operator (+) can also be used to concatenate strings.
Note that the operators above work only for numbers with compatible units:
h2 {
font-size: 5px + 2em; // error incompatible units
font-size: 5px + 2; // 7px
}
Moreover, multiplying two numbers of the same unit together will produce invalid CSS:
h2 {
font-size: 5px * 2px; // invalid CSS
}
As you might know, the / symbol is part of CSS shorthand properties. For example:
font: 16px / 24px Arial sans-serif;
background: url("http://example.com") no-repeat fixed center / cover;
But, as already mentioned Sass can take advantage of the forward slash (/) to perform the division operation.
So, let’s see how Sass understands this symbol:
h2 {
font-size: 16px / 24px // Outputs as CSS
font-size: (16px / 24px) // Uses parentheses, does division
font-size: #{$base-size} / #{$
