| 13 `<paper-input-container>` is a container for a `<label>`, an `<input is="iron-in
put">` or | |
| 14 `<iron-autogrow-textarea>` and optional add-on elements such as an error message
or character | |
| 15 counter, used to implement Material Design text fields. | |
| 16 | |
| 17 For example: | |
| 18 | |
| 19 <paper-input-container> | |
| 20 <label>Your name</label> | |
| 21 <input is="iron-input"> | |
| 22 </paper-input-container> | |
| 23 | |
| 24 ### Listening for input changes | |
| 25 | |
| 26 By default, it listens for changes on the `bind-value` attribute on its children
nodes and perform | |
| 27 tasks such as auto-validating and label styling when the `bind-value` changes. Y
ou can configure | |
| 28 the attribute it listens to with the `attr-for-value` attribute. | |
| 29 | |
| 30 ### Using a custom input element | |
| 31 | |
| 32 You can use a custom input element in a `<paper-input-container>`, for example t
o implement a | |
| 33 compound input field like a social security number input. The custom input eleme
nt should have the | |
| 34 `paper-input-input` class, have a `notify:true` value property and optionally im
plements | |
| 35 `Polymer.IronValidatableBehavior` if it is validatble. | |
| 36 | |
| 37 <paper-input-container attr-for-value="ssn-value"> | |
| 38 <label>Social security number</label> | |
| 39 <ssn-input class="paper-input-input"></ssn-input> | |
| 40 </paper-input-container> | |
| 41 | |
| 42 ### Validation | |
| 43 | |
| 44 If the `auto-validate` attribute is set, the input container will validate the i
nput and update | |
| 45 the container styling when the input value changes. | |
| 46 | |
| 47 ### Add-ons | |
| 48 | |
| 49 Add-ons are child elements of a `<paper-input-container>` with the `add-on` attr
ibute and | |
| 50 implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified whe
n the input value | |
| 51 or validity changes, and may implement functionality such as error messages or c
haracter counters. | |
| 52 They appear at the bottom of the input. | |
| 53 | |
| 54 ### Styling | |
| 55 | |
| 56 The following custom properties and mixins are available for styling: | |
| 57 | |
| 58 Custom property | Description | Default | |
| 59 ----------------|-------------|---------- | |
| 60 `--paper-input-container-color` | Label and underline color when the input is no
t focused | `--secondary-text-color` | |
| 61 `--paper-input-container-focus-color` | Label and underline color when the input
is focused | `--default-primary-color` | |
| 62 `--paper-input-container-invalid-color` | Label and underline color when the inp
ut is focused | `--google-red-500` | |
| 63 `--paper-input-container-input-color` | Input foreground color | `--primary-text
-color` | |
| 64 `--paper-input-container` | Mixin applied to the container | `{}` | |
| 65 `--paper-input-container-label` | Mixin applied to the label | `{}` | |
| 66 `--paper-input-container-input` | Mixin applied to the input | `{}` | |
| 67 | |
| 68 This element is `display:block` by default, but you can set the `inline` attribu
te to make it | |
| 69 `display:inline-block`. | |
