Smart Impact Bootstrap 5

This public fork is maintained by Smart Impact for Shopify themes that need runtime-overridable design tokens and reactive derived values. It remains based on Bootstrap 5.3.8 and retains Bootstrap's MIT license, copyright, API, Sass, and JavaScript module structure.

The fork has its own release cadence and compatibility policy. Changes from upstream Bootstrap are selected and integrated through pull requests rather than inherited automatically.

Quick start

Shopify themes should install the fork through an npm dependency alias. This preserves existing bootstrap/scss/... and JavaScript imports:

{
  "dependencies": {
    "bootstrap": "npm:@smartimpact-it/[email protected]"
  }
}

Alternatively, install the scoped package directly with npm install @smartimpact-it/[email protected].

For source development:

• Clone the repository: git clone [email protected]:siit-dev/bootstrap.git
• Install dependencies: npm ci
• Generate the distributions: npm run dist

Generated dist/ and js/dist/ files are intentionally absent from source control. They are rebuilt for npm packages and GitHub releases, so GitHub's automatic source archives are not standalone distributions.

Distribution contract

The package keeps Bootstrap's established entry points (main, module, style, and sass) and includes compiled CSS, RTL CSS, JavaScript bundles, individual plugins, source maps, Sass sources, and scss/runtime-tokens.json.

Custom releases use 5.3.8-smartimpact.N. Moving to a different upstream Bootstrap release changes the base version and is an explicit upgrade for consuming themes. npm run release-version -- <version> updates only the package and lockfile version; Bootstrap's upstream runtime/API version remains separate.

Read Bootstrap's Getting started page for the upstream framework documentation.

We provide compiled CSS and JS (bootstrap.*), as well as compiled and minified CSS and JS (bootstrap.min.*). Source maps (bootstrap.*.map) are available for use with certain browsers’ developer tools. Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper.

Bugs and feature requests

Have a fork-specific bug or feature request? Search existing and closed issues, then open an issue. Report issues reproducible in unmodified Bootstrap to the upstream project.

Documentation

Bootstrap’s documentation, included in this repository, is built with Astro. The upstream documentation is hosted at https://getbootstrap.com/. The docs may also be run locally.

Documentation search is powered by Algolia's DocSearch.

Running documentation locally

1. Run npm ci to install the Node.js dependencies, including Astro (the site builder).
2. Run npm run docs-build; it rebuilds the untracked CSS and JavaScript distributions before building the docs.
3. From the root /bootstrap directory, run npm run docs-serve in the command line.
4. Open http://localhost:9001 in your browser, and voilà.

Learn more about using Astro by reading its documentation.

Documentation for previous releases

You can find all our previous releases docs on https://getbootstrap.com/docs/versions/.

Previous releases and their documentation are also available for download.

Contributing

Versioning

Smart Impact release versions combine the upstream Bootstrap base with a fork revision, for example 5.3.8-smartimpact.1. Revisions with the same base preserve the supported Bootstrap 5.3 API unless a release note explicitly says otherwise. A new base version is treated as an explicit dependency upgrade.

See this repository's releases for fork changelogs and Bootstrap's releases for upstream history.
