 * ``lazySizesConfig.customMedia`` (default: ``{}``): The ``customMedia`` option object is an alias map for different media queries. It can be used to separate/centralize your multiple specific media queries implementation (layout) from the ``source[media]`` attribute (content/structure) by creating labeled media queries. (See also the [custommedia extension](plugins/custommedia)).
