Sass - @each Multiple Assignment with Maps

Description

The multiple assignment works well with maps and they are considered as lists of pairs. If you want to use the map, then you have to change @each statement and use multiple assignments.

Syntax

@each $var1, $var2 in <map>

The syntax is briefly explained below −

$var1, $var2 − These represents the name of the variables.
<map> − It represents lists of pair.

Example

The following example demonstrates the the use of multiple assignment with maps −

<html>
   <head>
      <title>Control Directives & Expressions</title>
      <link rel = "stylesheet" type = "text/css" href = "style.css"/>
   </head>

   <body>
      <h1>Welcome to Tutorialspoint</p>
      <h2>Welcome to Tutorialspoint</p>
      <h3>Welcome to Tutorialspoint</p>
   </body>
</html>

Next, create file style.scss.

style.scss

@each $header, $color in (h1: red, h2: green, h3: blue) {
   #{$header} {
      color: $color;
   }
}

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

h1 {
   color: red;
}

h2 {
   color: green; 
}

h3 {
   color: blue; 
}
