Sass - Interpolation
Description
It provides SassScript variables in selectors and property names using #{ } syntax. You can specify variables or property names within the curly braces.
Syntax
#{$name}
Where $name is the name of the variable or property name.
Example
The following example demonstrates the use of interpolation in the SCSS file −
<html> <head> <title>Interpolation</title> <link rel = "stylesheet" type = "text/css" href = "style.css" /> <link rel = "stylesheet" href = "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"> <script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script src = "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script> </head> <body> <div class = "container"> <h2>Example using Interpolation</h2> <p>SASS stands for Syntactically Awesome Stylesheet...</p> </div> </body> </html>
Next, create file style.scss.
style.scss
p:after { content: "I have #{8 + 2} books on SASS!"; }
You can tell SASS to watch the file and update the CSS whenever SASS file changes, by using the following command −
sass --watch C:\ruby\lib\sass\style.scss:style.css
Next, execute the above command; it will create the style.css file automatically with the following code −
style.css
p:after { content: "I have 10 books on SASS!"; }
Output
Let us carry out the following steps to see how the above given code works −
Save the above given html code in interpolation.html file.
