-<!--
-`<paper-input-container>` is a container for a `<label>`, an `<input is="iron-input">` or
-`<iron-autogrow-textarea>` and optional add-on elements such as an error message or character
-counter, used to implement Material Design text fields.
-
-For example:
-
-    <paper-input-container>
-      <label>Your name</label>
-      <input is="iron-input">
-    </paper-input-container>
-
-### Listening for input changes
-
-By default, it listens for changes on the `bind-value` attribute on its children nodes and perform
-tasks such as auto-validating and label styling when the `bind-value` changes. You can configure
-the attribute it listens to with the `attr-for-value` attribute.
-
-### Using a custom input element
-
-You can use a custom input element in a `<paper-input-container>`, for example to implement a
-compound input field like a social security number input. The custom input element should have the
-`paper-input-input` class, have a `notify:true` value property and optionally implements
-`Polymer.IronValidatableBehavior` if it is validatble.
-
-    <paper-input-container attr-for-value="ssn-value">
-      <label>Social security number</label>
-      <ssn-input class="paper-input-input"></ssn-input>
-    </paper-input-container>
-
-### Validation
-
-If the `auto-validate` attribute is set, the input container will validate the input and update
-the container styling when the input value changes.
-
-### Add-ons
-
-Add-ons are child elements of a `<paper-input-container>` with the `add-on` attribute and
-implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified when the input value
-or validity changes, and may implement functionality such as error messages or character counters.
-They appear at the bottom of the input.
-
-### Styling
-
-The following custom properties and mixins are available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-input-container-color` | Label and underline color when the input is not focused | `--secondary-text-color`
-`--paper-input-container-focus-color` | Label and underline color when the input is focused | `--default-primary-color`
-`--paper-input-container-invalid-color` | Label and underline color when the input is focused | `--google-red-500`
-`--paper-input-container-input-color` | Input foreground color | `--primary-text-color`
-`--paper-input-container` | Mixin applied to the container | `{}`
-`--paper-input-container-label` | Mixin applied to the label | `{}`
-`--paper-input-container-input` | Mixin applied to the input | `{}`
-
-This element is `display:block` by default, but you can set the `inline` attribute to make it
-`display:inline-block`.
