Bootstrap 5.2 Released: More CSS Variables and Bundler Guides

What happened

Bootstrap 5.2.0 was released on July 19, 2022, according to the official Bootstrap GitHub release. It continued the framework's gradual move toward CSS custom properties while adding developer-experience improvements and new component capabilities.

CSS variables and utilities

A key theme was extending CSS custom properties across more components and adding missing CSS variables, for example for the navbar-nav. The release also added the ability to generate local CSS variables on utilities when using the state option, and introduced $display-font-family and $display-font-style variables, continuing the groundwork that the color-mode system in 5.3 would build on.

Component features

Bootstrap 5.2 enabled smooth-scroll behavior in Scrollspy, added support for input groups in floating forms, truncated text to prevent multiline floating labels, and manually set hover and active backgrounds and borders for dark and light buttons. It also fixed a range of border-radius and validation issues across dropdowns, alerts and tooltips.

Rewritten bundler guides

On the documentation side, the release rewrote the Webpack and Parcel getting-started guides and added a brand-new Vite guide, reflecting the shift in the JavaScript tooling ecosystem. It also improved accessibility across examples and updated the code of conduct to Contributor Covenant 2.1.

Why it mattered

Bootstrap 5.2 was an incremental but important release that deepened the framework's adoption of CSS variables and modernised its build tooling guidance. The utility and CSS-variable work in particular laid the technical foundation for the first-class dark mode and color-mode system that arrived in Bootstrap 5.3.
