Interpolation of variables
Variable interpolation means the ability to build a string by using the values assigned to variables. In Sass, you can use variable interpolation to dynamically create property and selectors' names. In this recipe, you will learn how to apply variable interpolation in your code.
Getting ready
You can test variable interpolation in Sass with the Ruby Sass compiler. The Installing Sass for command line usage recipe of Chapter 1, Getting Started with Sass, describes how to install Ruby Sass on your system.
How to do it...
Perform the steps beneath to learn how to use variable interpolation in Sass to dynamically create property and selector names:
Write down the Sass code as follows in a Sass template called
interpolation.scss
:$name: class; $direction: left; $units: px; .#{$name} { margin-#{$direction}: 20#{$units}; }
Compile the Sass template from the previous step with Ruby Sass by running the following command in your console:
sass interpolation.scss
The compiled...
