v2.6.0b1

What's new - Theme Mode Support

You can now build a single card that automatically adapts to both Home Assistant Light and Dark themes.

The new Theme Mode editor introduces three editing modes:

• Auto (base value)
• Light
• Dark

For supported properties, you can define dedicated values for each theme while keeping a shared default. No more maintaining separate light and dark versions of the same card.

Advanced Customization

Theme Mode currently supports all major visual properties, including:

• text, background and border colors
• SVG fill and stroke colors
• chart colors
• background images and CSS gradients

Combined with Style Targets, every component can be customized independently for each theme, making it possible to create cards that look perfectly integrated regardless of the active Home Assistant theme.

Improvements

• Added global and card-specific editor settings
• Added icons for editor panel sections
• Panel sections are now collapsed by default for a cleaner workspace
• Expanded documentation with detailed guides for Gauges, Charts, Weather blocks and Theme Mode

Build once, customize for every theme, and share a single Marketplace card that looks great everywhere.
