take care in crafting instructional text—don't reference the spinner arrows, in case
they're not there!
Load Mike Taylor's support test (see
.html ) to determine what level of support a particular browser has for this input type.
If a user agent does not recognize the number input type, it will display a text input field.
Additional features
The min and max attributes can be used with the number input type to limit the values
that can be entered. In addition, you can use the step attribute to specify the amount
by which the value should be incremented. In this example, a customer must order in
pairs, so the minimum quantity is 2 and the step value is 2, as shown in Figure 3-13 :
<p><label>Quantity (must order in pairs of 2) <input type="number"
name="quantity" min="2" max="20" step="2" ></label></p>
<p><button type="submit">Submit</button></p>
Figure 3-13. Internet Explorer 10 Platform Preview 2 uses a text entry field for the number input
type, but it honors the min, max, and step attributes and will display an error if necessary
