Describe the issue

In the Building with Sass section, the examples are using an ampersand for the Sass variables, but I think they’re supposed to be dollar signs.

@color-mode-type: data !default;
@color-mode-type: media-query;

Change to:

$color-mode-type: data !default;
$color-mode-type: media-query;

Reduced test cases

Entering @color-mode-type: media-query; into a Sass file on VS Code causes an error.
