-Material Design: <a href="http://www.google.com/design/spec/components/text-fields.html">Text fields</a>
-
-`paper-input-decorator` adds Material Design input field styling and animations to an element.
-
-Example:
-
-    <paper-input-decorator label="Your Name">
-        <input is="core-input">
-    </paper-input-decorator>
-
-    <paper-input-decorator floatingLabel label="Your address">
-        <textarea></textarea>
-    </paper-input-decorator>
-
-Theming
--------
-
-`paper-input-decorator` uses `core-style` for global theming. The following options are available:
-
-- `CoreStyle.g.paperInput.labelColor` - The inline label, floating label, error message and error icon color when the input does not have focus.
-- `CoreStyle.g.paperInput.focusedColor` - The floating label and the underline color when the input has focus.
-- `CoreStyle.g.paperInput.invalidColor` - The error message, the error icon, the floating label and the underline's color when the input is invalid and has focus.
-
-To add custom styling to only some elements, use these selectors:
-
-    paper-input-decorator /deep/ .label-text,
-    paper-input-decorator /deep/ .error {
-        /* inline label,  floating label, error message and error icon color when the input is unfocused */
-        color: green;
-    }
-
-    paper-input-decorator /deep/ ::-webkit-input-placeholder {
-        /* platform specific rules for placeholder text */
-        color: green;
-    }
-    paper-input-decorator /deep/ ::-moz-placeholder {
-        color: green;
-    }
-    paper-input-decorator /deep/ :-ms-input-placeholder {
-        color: green;
-    }
-
-    paper-input-decorator /deep/ .unfocused-underline {
-        /* line color when the input is unfocused */
-        background-color: green;
-    }
-
-    paper-input-decorator[focused] /deep/ .floating-label .label-text {
-        /* floating label color when the input is focused */
-        color: orange;
-    }
-
-    paper-input-decorator /deep/ .focused-underline {
-        /* line color when the input is focused */
-        background-color: orange;
-    }
-
-    paper-input-decorator.invalid[focused] /deep/ .floated-label .label-text,
-    paper-input-decorator[focused] /deep/ .error {
-        /* floating label, error message nad error icon color when the input is invalid and focused */
-        color: salmon;
-    }
-
-    paper-input-decorator.invalid /deep/ .focused-underline {
-        /* line and color when the input is invalid and focused */
-        background-color: salmon;
-    }
-
-Form submission
----------------
-
-You can use inputs decorated with this element in a `form` as usual.
-
-Validation
-----------
-
-Because you provide the `input` element to `paper-input-decorator`, you can use any validation library
-or the <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/HTML5/Constraint_validation">HTML5 Constraints Validation API</a>
-to implement validation. Set the `isInvalid` attribute when the input is validated, and provide an
-error message in the `error` attribute.
-
-Example:
-
-    <paper-input-decorator id="paper1" error="Value must start with a number!">
-        <input id="input1" is="core-input" pattern="^[0-9].*">
-    </paper-input-decorator>
-    <button onclick="validate()"></button>
-    <script>
-        function validate() {
-            var decorator = document.getElementById('paper1');
-            var input = document.getElementById('input1');
-            decorator.isInvalid = !input.validity.valid;
-        }
-    </script>
-
-Example to validate as the user types:
-
-    <template is="auto-binding">
-        <paper-input-decorator id="paper2" error="Value must start with a number!" isInvalid="{{!$.input2.validity.valid}}">
-            <input id="input2" is="core-input" pattern="^[0-9].*">
-        </paper-input-decorator>
-    </template>
-
-Accessibility
--------------
-
-`paper-input-decorator` will automatically set the `aria-label` attribute on the nested input
-to the value of `label`. Do not set the `placeholder` attribute on the nested input, as it will
-conflict with this element.
