Sass - Media Directives

Description

@media directive sets the style rule to different media types. @media directive can be nested inside the selector SASS but it is bubbled up to the top level of the stylesheet.

Example

The following example demonstrates the use of @media in the SCSS file −

media.htm

<!doctype html>
   <head>
      <title>Media directive Example</title>
      <link rel = "stylesheet" href = "media.css" type = "text/css" />
   </head>

   <body class = "container">
      <h2>Example using media directive</h2>
      <img src = "/sass/images/birds.jpg" class = "style">
   </body>
</html>

Next, create file media.scss.

media.scss

h2 {
   color: #77C1EF;
}

.style {
   width: 900px;

   @media screen and (orientation: portrait) {
      width:500px;
      margin-left: 120px;
   }
}

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\media.scss:media.css

Next, execute the above command; it will create the media.css file automatically with the following code −

media.css

h2 {
   color: #77C1EF;
 }

.style {
   width: 900px;
}
@media screen and (orientation: portrait) {
   .style {
      width: 500px;
      margin-left: 120px;
   }
}
