Since the col class appears in every div, why not just include the float:left in the span classes? Just a thought. I’m new at this so maybe there’s some example to keep the flexibility of having it separate.

I can do it because I’ve never downloaded the Blueprint framework, and thus have no idea how they do what they do.

And now that I’ve downloaded it for a reference point, I can see that by “shamelessly copied,” you mean that they also used the word “span” to create widths (though theirs are written differently), meaning I wasn’t the first person on earth to conceive of a correlation between a colspan and a grid span. Mind boggling stuff.

Many frameworks share a lot of elements in common, since they’re trying to accomplish the same fundamental ends. For example, I guarantee that the YUI grid system uses the width property (though I’ve never downloaded it either). So by your logic, Blueprint is a ripoff of them, correct?

Bare minimum I would say that mine is different because it contains 9 rules, whereas theirs contains 240 rules. Or possibly because mine isn’t meant to be a standalone framework at all, but rather a starting point from which others can build their own framework (and thus understand how the framework works) instead of just grabbing someone else’s code and running. Had you actually stopped to read my article instead of skipping to the code, noticing a similarity, and then jumping to conclusions, you would have realized that was my whole point to begin with.

Thanks for playing,

If I might make a couple of suggestions, though. Name your col class something like .float-left, and your clear class to .clear-left.

This gives you the ability to use them in other places other than framework, and gives you a descriptive name so that you can remember what they were doing later on.
