Customization

Extend your theme

By default, the configuration provides a handful of general purpose background size utilities. You can easily extend the default scales using the Sass configuration.

@use "lasco" with (
    $extend: (
        "bg-size": (
            "50": "50%", /// One-value syntax.
            "50-auto": "50% auto", /// Two-value syntax.
            "multiple": "50%, 25%, 25%" /// Multiple backgrounds.
        )
    )
);

Note: the value can be a length or percentage value. ( Source MDN)
