| 12 `core-input` is an unstyled single-line input field. It extends the native | |
| 13 `input` element. | |
| 14 | |
| 15 Example: | |
| 16 | |
| 17 <input is="core-input"> | |
| 18 | |
| 19 The input's value is considered "committed" if the user hits the "enter" key | |
| 20 or blurs the input after changing the value. The committed value is stored in | |
| 21 the `committedValue` property. | |
| 22 | |
| 23 If the input has `type = number`, this element will also prevent non-numeric cha
racters | |
| 24 from being typed into the text field. | |
| 25 | |
| 26 Accessibility | |
| 27 ------------- | |
| 28 | |
| 29 The following ARIA attributes are set automatically: | |
| 30 | |
| 31 - `aria-label`: set to the `placeholder` attribute | |
| 32 - `aria-disabled`: set if `disabled` is true | |
