Input type "number" won't resize

Question

Why won't my input resize when I change the type to type="number" but it works with type="text"?

EXAMPLE

    Email: <input type="text" name="email" size="10"><br/>
  number: <input type="number" name="email" size="10">

Solution 1

Seem like the input type number does not support size attribute or it's not compatible along browsers, you can set it through CSS instead:

input[type='number']{
    width: 80px;
}

Incorrect usage.

Input type number it's made to have selectable value via arrows up and down.

So basically you are looking for "width" CSS style.

Input text historically is formatted with monospaced font, so size it's also the width it takes.

Input number it's new and "size" property has no sense at all*. A typical usage:

<input type="number" name="quantity" min="1" max="5">

w3c docs

to fix, add a style:

<input type="number" name="email" style="width: 7em">

EDIT: if you want a range, you have to set type="range" and not ="number"

EDIT2: *size is not an allowed value (so, no sense). Check out official W3C specifications

Note: The size attribute works with the following input types: text, search, tel, url, email, and password.

Tip: To specify the maximum number of characters allowed in the element, use the maxlength attribute.

Solution 3

Rather than set the length, set the max and min values for the number input.

The input box then resizes to fit the longest valid value.

If you want to allow a 3-digit number then set 999 as the max

 <input type="number" name="quantity" min="0" max="999">

Solution 4

For <input type=number>, by the HTML5 CR, the size attribute is not allowed. However, in Obsolete features it says: “Authors should not, but may despite requirements to the contrary elsewhere in this specification, specify the maxlength and size attributes on input elements whose type attributes are in the Number state. One valid reason for using these attributes regardless is to help legacy user agents that do not support input elements with type="number" to still render the text field with a useful width.”

Thus, the size attribute can be used, but it only affects older browsers that do not support type=number, so that the element falls back to a simple text control, <input type=text>.

The rationale behind this is that the browser is expected to provide a user interface that takes the other attributes into account, for good usability. As the implementations may vary, any size imposed by an author might mess things up. (This also applies to setting the width of the control in CSS.)

The conclusion is that you should use <input type=number> in a more or less fluid setup that does not make any assumptions about the dimensions of the element.
