Callout

ℹ️

While both `config()` and `theme()` in Tailwind CSS are used to access values defined in your `tailwind.config.js` file, they serve slightly different purposes and have different scopes of access.

CustomTable

theme()config()
Purpose: The theme() function is specifically designed to access values within the theme section of your Tailwind configuration.Purpose: The config() function is designed to access any value within the tailwind.config.js file, not just those within the theme section.
Scope: Limited to the theme section of tailwind.config.js.Scope: Can access the entire Tailwind configuration file, including custom configurations, variants, plugins, and other settings.
Usage: Primarily used to access design tokens like colors, spacing, fonts, etc., that are defined within the theme object.Usage: Used to retrieve configuration values that may not be strictly related to the theme, such as custom settings, variant configurations, or other top-level configuration options.
Context: Commonly used within custom utilities and variants to ensure consistent design tokens.Context: Useful when you need to access more than just the theme values, such as custom plugin settings or variant definitions.
