You can add custom CSS rules to WordPress to style your directories and location maps without having to wait for a custom Store Locator Plus® style or a theme that supports full CSS rules. WordPress has a built-in CSS customization tool that applies to all pages on the site.
You can use this custom CSS tool to do things like format the MySLP SaaS, or WPSLP plugin, directory listings.
How To Add Custom Rules
Login to your site as a site administrator.
Click on the Customize menu entry in the admin toolbar.
Click on Additional CSS in the sidebar.
Enter a fully qualified CSS rule.
