Sass - Color Operations

Description

SASS allows using color components along with the arithmetic operations and any color expression returns a SassScript color value.

Example

The following example demonstrates the use of color operations in the SCSS file −

<html>
   <head>
      <title>Color Operations</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">
         <h3>This is Example of Sass Color Operations</h3>
         <p>SASS stands for Syntactically Awesome Stylesheet..</p>
      </div>
   </body>
</html>

Next, create file style.scss.

style.scss

$color1: #333399;
$color2: #CC3399;

p{
   color: $color1 + $color2;
}

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 {
   color: #ff66ff;
}
