Bass Jobsen lives in Orthen in the Netherlands. Bass tries to combine his interests in web technology with his compassion for a sustainable lifestyle. He therefore not only owns a web development company, but is also board member at the Energie Cooperatie 073. In his spare time, he plays tennis and spends a lot of time with his kids Kiki, Dries, Wolf, and Helena.
Bass has been programming the web since 1995, ranging from C to PHP. He is always looking for the most accessible interfaces. He has a special interest in the processes between designer and programmer. Web interfaces should work independently of devices or browsers in his opinion. He also works on the accessibility of Bootstrap and his JBST WordPress starters theme.
Delivering readable and maintainable code is important for his daily job so that's why he loves CSS preprocessors and other tools that stimulate DRY (Don't Repeat Yourself) coding in web development. Also, Bootstrap helps him to work faster and make his clients and users more content.
With over 5 years of experience with Bootstrap, Bass has been actively contributing to the community with his blogs (http://bassjobsen.weblogs.fm/) and Git repos (https://github.com/bassjobsen). He has created sites such as http://www.streetart.com/ with Bootstrap. The newest version of JBST for Bootstrap 4 is already available at https://github.com/bassjobsen/jbst-4-sass. He released a CLI for Bootstrap 4 in March 2016 (https://github.com/bassjobsen/bootstrap-clii).
In the summer of 2016, Bass started teaching programming Scratch for primary school kids using the Massive Open Online Courses (MOOCs) on the edX-platform offered by Delft University of Technology.
He is also the author of, among others, Sass and Compass Designer's Cookbook with Packt Publishing and some other books on Less (Leaner CSS).

David Cochran serves as an Associate Professor of Communication at Oklahoma Wesleyan University. He has been teaching Interactive Design since 2005. A passion for best practices induced him to avoid shortcuts and hew towards web standards. When Twitter Bootstrap was first released in August 2011, he recognized it as a tool that would speed up development while supporting best practices. Thus, he began folding Bootstrap into his university courses, much to the benefit of his students. In 2012, David produced a Bootstrap 2.0 tutorial series for webdesign.tutsplus.com. He also published a first short book about Bootstrap, Twitter Bootstrap Web Development How-To, Packt Publishing.

Ian Whitley developed a passion for writing and literature at a young age. In 2010, he developed a deep interest in web development and decided to get involved in it. When the opportunity to help write a book on web development came up, it seemed like too good of an offer to pass up. He was one of the early adopters of Twitter Bootstrap when it was first released in 2011. With the help of David Cochran, he quickly conquered the system and has used it for many different web projects. Currently, he uses Bootstrap in relation to WordPress, using both in conjunction to create custom and creative solutions for his client.
Living in the Bartlesville, OK, Ian is the lead developer for BitBrilliant, the company that David Cochran founded. He is always looking to further his skills?both for the web and in the many hobbies he pursues, which include leather working and writing.
