SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bootstrap theming is often daunting, requiring deep Sass and CSS variable mastery to implement branded color schemes, dark modes, and component-level tweaks.

Core Features & Use Cases

CSS Variables (runtime theming): override --bs-* values without recompiling.
Sass Variable Overrides: set $primary, $bg, and spacing before importing Bootstrap.
Color Modes & Theming: add data-bs-theme or color-mode mixins to support light/dark scenarios.
Use Case: teams deploy a branded Bootstrap theme across multiple apps with consistent typography, spacing, and color palettes.

Quick Start

Set up a themed Bootstrap workflow by defining Sass variables, then importing Bootstrap, and apply CSS variables across the app. For example, place colors and typography in a variables file, override on :root or [data-bs-theme], compile, and test across light/dark modes.

FAQPage Schema

How do I customize Bootstrap colors with Sass variables?▼

Customizing Bootstrap with Sass variables requires defining overrides like $primary in a file imported before the main Bootstrap stylesheet. This establishes your branded color palette and spacing rules prior to compilation.

What is the best way to implement dark mode in Bootstrap?▼

Implementing Bootstrap dark mode involves using color-mode mixins and setting data-bs-theme attributes or media queries. This enables light and dark scenarios by swapping CSS custom properties at runtime.

Can I override Bootstrap CSS variables at runtime without recompiling?▼

Yes, you can override Bootstrap CSS variables at runtime by modifying --bs-* custom properties. This enables dynamic runtime theming and color palette updates without recompiling Sass.

Does Bootstrap theming work for deploying a theme across multiple apps?▼

Bootstrap theming supports multiple app deployments by centralizing Sass variable overrides and CSS custom properties into a shared workflow. Teams use this setup to deploy consistent typography and color palettes across projects.

When do I need to use Sass variables versus CSS custom properties for Bootstrap theming?▼

Use Sass variables for structural changes like spacing and typography requiring compilation, and CSS custom properties for runtime color updates. Combining both allows static tokens to compile while colors adapt dynamically across modes.
