YAML-only Advanced Features

[superdingo101]

Before requesting a feature: some advanced options are YAML-only

Daylight Calendar Card supports many features that are not available in the visual configurator yet.

If you are looking for advanced styling, conditional formatting, calendar grouping, or custom layout tweaks, the feature may already exist but require YAML configuration.

Common YAML-only features

Conditional event styling: event_styles

Use event_styles to change how events look based on title, calendar, location, description, all-day status, regex matches, or other conditions.

Examples:

• Make soccer events blue
• Hide events from a specific calendar
• Change font colors for matching events
• Style events differently by keyword
• Use regex matching for advanced rules

Conditional day styling: day_styles

Use day_styles to change how calendar days look based on conditions.

Examples:

• Highlight today
• Shade weekends
• Dim past days
• Highlight days with events
• Highlight days with events from a specific calendar
• Highlight days with events matching a title

Documentation:

https://github.com/superdingo101/daylight-calendar-card/wiki/Configuration#day_styles

Virtual grouped calendars: virtual_calendars

Use virtual_calendars to create dashboard-only calendar groups.

Examples:

• Combine several school calendars into one visible “School” calendar
• Group multiple kids’ calendars under one display calendar
• Create a simplified set of calendar toggles for the card

Advanced CSS styling: uix

Use uix for advanced CSS customization.

Examples:

• Fine-tune spacing
• Override specific card sections
• Customize layout beyond built-in options
• Apply CSS selectors directly to the card

Why are these YAML-only?

The visual editor currently focuses on common options: calendars, views, colors, layout, background images, event display, and basic behavior.

Some advanced features use nested rules, priorities, match conditions, regex, or custom CSS. These are much easier and more reliable to configure in YAML.

How to edit the card YAML

1. Edit your Home Assistant dashboard.
2. Edit the Skylight Calendar Card.
3. Open the card editor menu.
4. Choose Show code editor.
5. Add the YAML option manually.
6. Save.

Before opening a feature request

Please check the wiki first:

https://github.com/superdingo101/daylight-calendar-card/wiki/Configuration

If the feature exists but is YAML-only, feel free to open a request asking for it to be added to the visual editor.

That is different from requesting support for the feature itself.
