It is true that Bootstrap has grown to include supporters from all around the globe. As there are plans for a Bootstrap 3 release I want to go into detail for one topic in particular. The Bootstrap JavaScript effects are not always useful to developers, so JS files are not necessary for running the whole framework. But they do provide quicker features to define common UI elements without having to reinvent the wheel. I want to focus this tutorial on using modal windows within a typical webpage. We just need to include two files out of the Bootstrap framework. And the JS codes are not overly complicated to understand. My example demo allows users to dynamically update the background color, so this does admittedly have some more sample JS then you will need. But it is an excellent introduction to adding these brief components into any ordinary website.
