The output value is flat along an interval. You control the number of intervals and whether or not the change in output value happens at the start or the end. There are some shorthands, step-start and step-end, which provide the common case - a single discrete change in output.

We have not yet implemented the steps() function in WebKit. Hopefully very soon though!
