inputMode HTML attribute

While working on a form with numeric inputs, I noticed Claude putting this attribute on them: inputMode="numeric".

Intrigued, I looked at the MDN page and it turns out the attribute exists to support different input styles, mostly related to what a smartphone will show in the keyboard tray. It can take values like tel, email, numeric and so on.

The attribute’s effect is limited to the keyboard, and it relies on the specific vendor to act on it. Nevertheless, I find it pretty useful to be able to change the keyboard between numeric and decimal depending on the value that needs to be entered in a form field.
