Frequently asked questions
What do the prefix and suffix do?
They are placed before and after each generated number, so you can produce values like item-1 or 1px.
Can the step be larger than one?
Yes. The step sets the gap between values, so you can count by twos, fives or any interval.
Is pasted text needed?
No. The sequence is created entirely from the start, end, step, prefix and suffix controls.
