What are some good and simple IDEs for writing CSS/HTML code on the Mac?
I realize a similar question has been asked before (here, for example), but most answers are about Windows tools.
This list includes some CSS IDEs for Mac OS, but it would be good to know which ones are popular (and the list is probably not complete).
I'm looking for something simple that helps me write CSS code, e.g. pops up a list with possible attributes of an element as I type, does code completion etc.
