#ootstrap, originally named Twitter Blueprint, was deeloped by Mar$ 1tto and !acob Thornton

at Twitter  as a framewor$ to encourage consistency across internal tools. #efore #ootstrap, arious

libraries were used for interface deelopment, which led to inconsistencies and a high maintenance

burden. &ccording to Twitter deeloper Mar$ 1tto7

%& super small group of deelopers and I got together to design and build a new internal tool and

saw an opportunity to do something more. Through that process, we saw ourseles build something

much more substantial than another internal tool. Months later, we ended up with an early ersion of

#ootstrap as a way to document and share common design patterns and assets within the

company.%/0
