About Bootstrap

Bootstrap was created at Twitter in mid-2010 by @mdo and @fat. Prior to being an open-sourced framework, Bootstrap was known as Twitter Blueprint. A few months into development, Twitter held its first Hack Week and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so even today.

Bootstrap’s influence reached Scania in 2014, when Jesper Karlsson introduced the company’s first design system — built on Bootstrap. In 2018, it evolved into a multibrand, component-based design system known as Corporate UI. In 2021, the foundation was brought back into Scania as a single-brand DS — the Scania Digital Design System — before being renamed and well invested in as Tegel, which has remained the go-to design system for Scania ever since. You’ll find Tegel at tegel.scania.com.

But the story didn’t end there. When TRATON was newly formed in 2021, Jesper tried to bring Corporate UI along, but the supporting organization was too small at the time to handle the demands of several brands. So Bootstrap stepped in once again — TRATON Bootstrap quietly lived in the shadows, but did well in supporting developers across a range of applications while no other organization was building anything more solid.

In 2026, a CSS-only version of Tegel was finally released in Beta, and it included a TRATON-developed theme as well. To support applications nearing the end of their lifecycle, Tegel Lite was made available as an adoption path — closing the loop on more than a decade of Bootstrap-rooted design system work across Scania and TRATON. For Jesper, the final chapter was written together with Malin Marques, who now steers the ship and handles any production-critical updates, since the Bootstrap Edition is no longer actively maintained.

During the adoption of Tegel Lite, Bootstrap has once again proved itself — this time as a highly capable framework for conversational maintenance, where solid documentation, add-on plugins, and a mature core give small teams the potential to accomplish great results.
