The step attribute specifies the legal number intervals for an <input> element. A tip is to use the step attribute together with the max and min attributes to create a range of legal values. The step attribute works with the following input types: number, range, date, datetime, datetime-local, month, time and week.
For example: if step="3", legal numbers could be -3, 0, 3, 6, etc. for this document which shows an input field with such specified legal number intervals:

This attribute is compatible with most major browsers, except Firefox.
