Expected indentation of 4 spaces but found 6.
Open

      float: left;

Indentation

Rule indentation will enforce an indentation size (tabs and spaces) and it will also ensure that tabs and spaces are not mixed.

The mixed spaces and tabs warnings check will take into account what you have set in your config file whether it should expect to see spaces or tabs. If it encounters a tab anywhere in a file when your rule config doesn't specify tabs it will flag a lint warning, Similarly for any whitespace using spaces when tabs are specified. Obviously spaces between properties and values etc are ignored.

Options

  • size: number or 'tab' (defaults to 2 spaces)

Examples

When enabled (assuming size: 2) the following are allowed:

.foo {
  content: 'bar';

  .baz {
    content: 'qux';

  • ignore-custom-properties: true/false (defaults to false)

Property orders: https://github.com/sasstools/sass-lint/tree/develop/lib/config/property-sort-orders

Examples

When enabled (assuming order: alphabetical), the following are allowed:

.foo {
  content: 'baz';
  height: 100vh;
  width: 100vw;
}

When enabled (assuming order: alphabetical), the following are disallowed:

.foo {
  width: 100vw;
  height: 100vh;
  content: 'baz';
}

Custom Sort Orders

You have the option to create your own custom property sort orders. These are specified in your .sass-lint.yml file as below:

property-sort-order:
  - 1
  -
    order:
      - border
      - display
      - color

When the custom order is specified as above, the following are allowed:

.foo {
  border: 1px solid blue;
  display: block;
  color: red;
}

When the custom order is specified as above, the following are disallowed:

.foo {
  display: block;
  color: red;
  border: 1px solid blue;
}

Ignore Custom Properties

When ignore-custom-properties: false (assume order: 'alphabetical') the following would be allowed

.foo {
  border: 1px solid blue;
  color: red;
  composes: heading;
  display: block;
}

When ignore-custom-properties: false (assume order: 'alphabetical') the following would be disallowed

.foo {
  composes: heading; // not in alphabetical order
  border: 1px solid blue;
  color: red;
  display: block;
}

When ignore-custom-properties: true (assume order: 'alphabetical') the following would be allowed

.foo {
  composes: heading; // custom properties ignored
  border: 1px solid blue;
  color: red;
  display: block;
}
