If the value of the max attribute isn't a number, then the element has no maximum value. The minimum value to accept for this input. If the value of the element is less than this, the element fails constraint validation. If a value is specified for min that isn't a valid number, the input has no minimum value. The placeholder attribute is a string that provides a brief hint to the user as to what kind of information is expected in the field. It should be a word or short phrase that demonstrates the expected type of data, rather than an explanatory message.

The text must not include carriage returns or line feeds. If the control's content has one directionality LTR or RTL but needs to present the placeholder in the opposite directionality, you can use Unicode bidirectional algorithm formatting characters to override directionality within the placeholder; see Overriding BiDi using Unicode control characters in The Unicode Bidirectional Text Algorithm for those characters.

When you create a number input with the proper type value, numberyou get automatic validation that the entered text is a number, and usually a set of up and down buttons to step the value up and down.
