To customize your filters’ appearance please visit the annasta Filters section of your WordPress Customizer (see Appearance > Customize > annasta Filters).
Please enable the “Default” style to be able to use all the options of annasta Filters Customizer.
For backwards compatibility with sites that have their styling dependent on old annasta style sheet, it is included in the plugin package under the name of “Deprecated since version 1.3.0”. Please don’t use it on newer versions of the plugin, for it does not support the options of the annasta Filters Customizer or any functionality added since the release of version 1.3.0.
