Restricting Input to Numbers in HTML

In HTML, you can restrict an input field to accept only numbers by using the type="number" attribute. This ensures that the browser only allows numeric input and shows a numeric keyboard on mobile devices.

Ways to Restrict Input to Numbers

1
Use <input type="number"> to accept only numeric values.
2
Add min and max attributes to set allowed numeric ranges.
3
Use the step attribute to control increments (e.g., step="1" for integers).
