The result is a uniform appearance for prose, tables and form elements across web browsers. Once added to a project, Bootstrap provides basic style definitions for all HTML elements. As such, the primary factor is whether the developers in charge find those choices to their liking.

Mark suspended work on Bootstrap 3 on September 6, 2016, to free up time to work on Bootstrap 4. The first beta version was released on August 10, 2017.
The first alpha version of Bootstrap 4 was released on August 19, 2015. Mark Otto announced Bootstrap 4 on October 29, 2014. Bootstrap 3 dropped Internet Explorer 7 and Firefox 3.6 support, but there is an optional polyfil for these browsers. Bootstrap 3 features new plugin system with namespaced events.

This version supports responsive web design, meaning the layout of web pages adjusts dynamically, taking into account the characteristics of the device used (whether desktop, tablet, or mobile phone). On January 31, 2012, Bootstrap 2 was released, which added built-in support for Glyphicons, several new components, as well as changes to many of the existing components. It has continued to be maintained by Mark Otto, Jacob Thornton, and a small group of core developers, as well as a large community of contributors. It was renamed from Twitter Blueprint to Bootstrap, and released as an open source project on August 19, 2011. Īfter a few months of development by a small group, many developers at Twitter began to contribute to the project as a part of Hack Week, a hackathon-style week for the Twitter development team. Months later, we ended up with an early version of Bootstrap as a way to document and share common design patterns and assets within the company. Through that process, we saw ourselves build something much more substantial than another internal tool. According to Twitter developer Mark Otto:Ī super small group of developers and I got together to design and build a new internal tool and saw an opportunity to do something more. Before Bootstrap, various libraries were used for interface development, which led to inconsistencies and a high maintenance burden. History Early beginnings īootstrap, originally named Twitter Blueprint, was developed by Mark Otto and Jacob Thornton at Twitter as a framework to encourage consistency across internal tools.
