html5How to limit the number of input numbers
If we want to limit the number of input numbers in html, we can use the max of the input tag attributes and min attributes.
The max attribute specifies the maximum value allowed for the input field. The min attribute is used to specify the minimum value allowed for the input field. Tip: The max attribute is used in conjunction with the min attribute to create a legal value range.
The syntax is as follows:
<input max="number|date"> <input min="number|date">
