Part of the fun of being fluent in various programming languages is messing around with new toolsets. I've talked many times about making a mobile friendlier version of the tracking system, to encourage users to submit on the fly rather than having to boot up the old pc. The Twitter Bootstrap API is a code framework that is geared toward responsive web design.
What is responsive design?
Responsive design is an approach to developing web content that in simple terms, looks sexy on any device used to view. With the rise in tablets, mobile devices, laptops of all sizes and strengths, it is increasingly becoming a baseline requirement to make websites viewable across all of them.
Responsive design is a solution for this design challenge. Formerly, each device type would require a complete dedicated code base to handle rendering the website. This would mean duplication or even triplication of code to accomplish this. That is a ton of effort to maintain, which is why previously most websites simply were for desktop only, requiring users on mobile devices to "pinch in" to read and reformat on their own.
