Bootstrap badly needs a really good tutorial. I'm thinking of making one, if anybody wants to help out, my email address is in my profile.
I was thinking I'd build a simple and attractive site from scratch and make the tutorial a step-by-step of how it was done, so even somebody with no HTML or CSS experience could do it - but also so that even experienced programmers would quickly learn all sorts of cool things that Bootstrap can do.
This is how I'm learning Rails right now - the Rails tutorial is amazing. Bootstrap needs something similar.
Yes! Bootstrap has some hierarchy things you have to pick up on to get desired effects. Some kind of guide would be nice. I'm not sure if they've updated it since but a few months ago I was building a layout and had to resort to the inspector tool to figure out the exact way they did things in the examples.
