Widget Content Option: Advanced
The Advanced option in the Options bar is similar to the Design Bar’s Advanced option, but applies only to this column/slide/tab etc.
You can add a custom class name here to apply custom styles to this or other columns where the custom class is added. The custom CSS selecting this class can be added to the widget’s Advanced option in the Design Bar to affect just this widget, or in the global CSS or DevKit panels in the customizer. See How to Customize Your Site With CSS for details on CSS customization in Layers.
- Add class names without a dot. Example: feature-column and not .feature-column
- Class names should be unique. Example: my-feature-column has a better chance of being unique, column is not at all unique. This is important to ensure your custom class is not already in use or defined, which may lead to conflicts.
