At the risk of sounding like an asshole. The themes on prebootstrap is pretty average at best. Alternatives like bootswatch.com offers far better themes.
I took this as a quick intro to snippets of Bootstrap features. Ex: Logins and stuff. It does say "pre" bootstrap so I'm sure that was the intended purpose for this.
Great resource! This is also worth attention: http://bootswatch.com/. I have zero-to-none design skills and using these themes makes my chrome extensions design look acceptable (well, almost)
it saved me some work recently as I got to the 'ok, time to dress this up a bit' phase of a project. still recognizable as Bootstrap, but also an easy way to inject a bit of design and good taste in a prototype.
I believe they intend for you to use them as building blocks. You can use their layouts to get your idea on the screen, then add additional CSS in order to 'make it your own'.
They're the only resource available if you have to do coursework, or you live in a country where access to international credit cards is not trivial for example.
I now have an international credit card, but for a long time my barrier was not money, but money transmission :) , I would have gladly paid U$ 5 or 10 or even 15. Most of the credit cards issued here in Uruguay are local-only, and the requirements are pretty hefty (more than half the population is not eligible for an international credit card).
I purchased a template for my side project, on ThemeForest (they have some Bootstrap-based templates over there too).
I was thinking more along the lines of classes which I took in the past, for example a course in Java, where one of the items was a JSF-based web site, which I plugged to a free bootstrap template, where web design wasn't the focus and I was busy trying to understand other things.
I agree that if you work in web design, you should know to do this stuff from the docs.
He doesn't understand that "cascading" part of CSS. Replacing core bootstrap files wouldn't make any sense, and it's better to add them downstream so that they can be changed or removed or whatever.
