Shiny Bslib Theming

What it does

This skill enables AI agents to apply custom theming styles to Shiny applications built with bslib. It allows dynamic modification of layout, colors, and typography directly within the R environment.

When to use it

• You need to match a Shiny app's visual identity to your organization's brand guidelines without hardcoding CSS.
• You want to create reusable theme configurations that can be toggled or updated programmatically across multiple apps.
• You are building dashboards where the same underlying data visualization needs different aesthetic treatments for distinct user groups.

Key capabilities

• Applies bslib-based themes to Shiny UIs dynamically.
• Modifies layout structures and component styling via R code.
• Facilitates consistent design patterns across diverse Shiny applications.

Example prompts

• "Apply a dark mode theme to this Shiny app using the shiny-bslib-theming skill."
• "Create a custom corporate theme for my dashboard that uses specific blue and gray color palettes defined in R."
• "Update the typography and spacing of this existing Shiny interface to match a new design system."

Tips & gotchas

Ensure your Shiny app is already utilizing bslib as its layout engine, as this skill relies on those underlying structures. While powerful for customization, complex theme overrides may require advanced knowledge of CSS variables and R list manipulation to resolve conflicts effectively.
