Global CSS Variables

Global CSS variables are the foundation of the BEEQ theme system. They cover brand colors, neutrals, typography, spacing, radius, shadows, and strokes. On top of these base variables, semantic tokens map each value to a specific role in the UI — backgrounds, text, borders, icons, UI elements, and interactive states — and automatically adapt to light and dark mode.

Base variables are the foundation of your theme and should be set at the root level for global consistency. See the Custom Theme page for details on overriding them.

Base theme variables

Base variables define the raw design values for your theme. They are set once at the root level and consumed by the declarative color variables above them.

Brand & accent colors

Your primary brand identity and the secondary highlight color.

--bq-brand-light:  /* Light variant of brand color */
--bq-brand:        /* Main brand color */
--bq-brand-dark:   /* Dark variant of brand color */

--bq-accent-light: /* Light variant of accent color */
--bq-accent:       /* Main accent color */
--bq-accent-dark:  /* Dark variant of accent color */

State colors

Used to convey meaning in the UI for actions and states such as success, danger, warning, and info.

/* Success — for positive actions and states */
--bq-success-light: /* Light success color */
--bq-success:       /* Main success color */
--bq-success-dark:  /* Dark success color */

/* Danger — for errors and destructive actions */
--bq-danger-light:  /* Light danger color */
--bq-danger:        /* Main danger color */
--bq-danger-dark:   /* Dark danger color */

/* Warning — for cautionary messages */
--bq-warning-light: /* Light warning color */
--bq-warning:       /* Main warning color */
--bq-warning-dark:  /* Dark warning color */

/* Info — for informational messages */
--bq-info-light:    /* Light info color */
--bq-info:          /* Main info color */
--bq-info-dark:     /* Dark info color */

/* Focus — for focus indicators */
--bq-focus:         /* Focus ring color */

Neutral colors

The neutral color scale provides a range of grays for backgrounds, borders, and text.

--bq-white: /* Pure white or near-white */
--bq-black: /* Pure black or near-black */

/* Neutral scale (50–1000) */
--bq-neutral-50:    /* Lightest neutral */
--bq-neutral-100:   /* Very light neutral */
--bq-neutral-200:   /* Light neutral */
--bq-neutral-300:   /* Light-medium neutral */
--bq-neutral-400:   /* Medium-light neutral */
--bq-neutral-500:   /* Medium neutral */
--bq-neutral-600:   /* Medium-dark neutral */
--bq-neutral-700:   /* Dark-medium neutral */
--bq-neutral-800:   /* Dark neutral */
--bq-neutral-900:   /* Very dark neutral */
--bq-neutral-950:   /* Extra dark neutral */
--bq-neutral-1000:  /* Darkest neutral */

BEEQ also provides an extensive primitive color palette — blue, coral, cyan, gold, green, indigo, iris, lime, magenta, orange, purple, red, sky, teal, volcano, and yellow (each with 10 shades, 100–1000). Use these when defining brand and accent tokens in a custom theme.See the Colors page for the full palette and guidance on usage.

State colors

Used for interactive states like hover and active. They blend with a base color using the CSS color-mix() function for better visual feedback.

--bq-state--hover:  /* Hover state blend color */
