Sass - @each Multiple Assignment

Description

Multiple values can also be used with @each directive like $var1, $var2, $var3, ... in <list>.

Syntax

@each $var1, $var2, $var3 ... in <list>

The syntax is briefly explained below −

$var1, $var2 and $var3 − These represent the name of the variables.
<list> − It represents list of lists, each variable will hold the element of the sub-lists.

Example

The following example demonstrates the the use of @each directive with multiple values −

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

   <body>
      <p class = "aqua">This is line one.</p>
      <p class = "red">This is line two.</p>
      <p class = "green">This is line three.</p>
   </body>
</html>

Next, create file style.scss.

style.scss

@each $color, $border in (aqua, dotted), (red, solid), (green, double){
   .#{$color} {
      background-color : $color;
      border: $border;
   }
}

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

.aqua {
   background-color: aqua;
   border: dotted;
}

.red {
   background-color: red;
   border: solid; 
}

.green {
   background-color: green;
   border: double;
}
