Who developed bootstrap?

Bootstrap, formerly known as Twitter Blueprint, was written and developed by Mark Otto and Jacob Thornton of Twitter. The original intention was to create a set of tools and frameworks that can maintain consistency.

Before Bootstrap, developing interfaces required using different code libraries, which could easily lead to inconsistencies and increase the burden of maintenance.

Twitter developer Mark Otto said:

"I was working with a few developers to design and create a new tool for internal use, and then we saw an opportunity to do more. From After that, we found that the tool we designed was more powerful than others. A few months later, we prototyped Bootstrap and shared documentation, designs, and resources within the company."

After a group discussion After months of hard work, many developers at Twitter regarded it as part of Hack Week (a week similar to a hackathon popular among Twitter developers) and began to participate in development.

We renamed Twitter Blueprint to Bootstrap and released it as an open source project on August 19, 2011. Since then the project has continued to be maintained by Mark Otto, Jacob Thornton and a core development team, in addition to numerous contributors from the community.

On January 31, 2012, Bootstrap 2 was released. This version adds a twelve-column grid layout and responsive components, and makes changes to many components. Bootstrap 3 was released on August 19, 2013. It began to prioritize mobile devices and began to use flat design.

On April 23, 2015, Mark Otto announced that Bootstrap 4 was being developed. The first alpha version of Bootstrap 4 was deployed on August 19, 2015.
