A form should feel easy to use. The visitor sees a question, gives an answer, and needs to know what will happen next.
What You Need to Know
Inputmode suggests a suitable on-screen keyboard on mobile devices without changing the submitted value type.
In this example: use inputmode=numeric on a postal code field.
Try the Example
Take a look at the example. We’ll explain the important lines right below it.
<form action="/address" method="post">
<label for="postal-code">Postal code</label>
<input id="postal-code" name="postal-code" inputmode="numeric" autocomplete="postal-code">
<button type="submit">Save</button>
</form>Let’s Read the Code
- <form>: The form groups controls and identifies where submitted data goes.
- <label>: The label tells people what the input is for. A matching for/id pair makes the label clickable.
- for: For connects a label or output with a control by ID.
- id: An id uniquely identifies an element on this page.
Read the named elements and attributes together. They explain how the browser connects this feature to the rest of the page.
What Happens in the Browser?
The HTML controls work in the browser, but saving an answer requires the example action path to be handled by a real server.
Where does the answer go? The example uses the submitted name(s) postal-code. Those names help the receiving server identify each answer. A label is for people; a name attribute is for the form data; an ID connects elements in the page.
Your Turn
Move through the example without a mouse. Read each control name and current state aloud as if describing it to a friend.
Common Beginner Mistakes
- Copying the example without giving the fields a clear label and a usable name.
- An inputmode hint is not validation. Numeric keypads may still allow non-digit input.
Key Takeaways
- A control needs a clear label and, when submitted, a meaningful name and value.
- <form>: The form groups controls and identifies where submitted data goes.
- A meaningful HTML element is usually a stronger starting point than adding an ARIA role to a generic div. Also check what happens using only the keyboard.
