HTML step Attribute

<input type="submit">
</form>Meaning
The step attribute defines the step in which values can take.
The step defaults to 1 for number and range.
In date/time input types, step is expressed in seconds, with the default step being 60 seconds. The step scale factor is 1000 (which converts the seconds to milliseconds, as used in other algorithms).
Example:
- if step="2", legal numbers could be -2, 0, 4, 6, etc.
- if step="3", legal numbers could be -3, 0, 3, 6, etc.
