Sass - Debug Directives


Advertisements

Description

The @debug directive detects the errors and displays the SassScript expression values to the standard error output stream.

Example

Given below is the stylesheet file saved with extension .scss, which is similar to the css file.

debug.scss

$font-sizes: 10px + 20px;
$style: (
   color: #bdc3c7
);

.container {
   @debug $style;
   @debug $font-sizes;
}

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\debug.scss:debug.css

When you run the above command, it will create the debug.css file automatically. Whenever you change the SCSS file, the debug.css file will be updated automatically.

Output

Let's carry out the following steps to see how above code works and gives you debug error −

  • Save the above given code in debug.scss file.

  • Run the above mentioned command line in the command prompt.
