Since Moodle 4.5, the Atto editor is no longer part of the Moodle core. TinyMCE is the new standard editor. For many, this meant worrying about losing tried-and-tested Atto styles. Our new elediaStyles plugin for TinyMCE prevents exactly that.
The plugin was developed by eLeDia for the SDG Campus as part of the Open T-Shape for Sustainable Development project, which was funded by the Foundation for Innovation in Higher Education from 2021 to 2025.
The plugin allows you to define your own style and format templates using CSS and conveniently select them via a dropdown menu in the editor, including identical display in edit and read mode. Existing Atto styles can usually continue to be used, so familiar workflows are retained even after changing editors.

Good to know
eLeDia developed the plugin for Moodle 4.5 because it is the latest Moodle long-term support release (LTS). The new Moodle 5.3 (LTS version) will not be released until October 2026.
