Page not rendering when I import "Paper-input" - polymer

The problem I am having here is that the page renders fine when I do not import "paper-input". But when I import "Paper-input" the page does not render. I have not tested any other imports at the moment to see if the page renders. Any ideas why it doesn't render? I've just tried using the imports from the polymer website such as "" and it does not work. Also I have created a test file using all imports starting with the http and it seems to work fine. I do prefer to have the imports locally on my server instead of using the online sources.

Polymer2.0 - Looking for json format icon - { } using paper icon

I was looking for json format icon from the polymer iron icons list which is not available
something similar to http://cdn.mysitemyway.com/etc-mysitemyway/icons/legacy-previews/icons/high-resolution-dark-blue-denim-jeans-icons-alphanumeric/072287-high-resolution-dark-blue-denim-jeans-icon-alphanumeric-bracket-curley.png
I am tried below workaround but it didnt work either

<paper-icon-button> has a src property to specify the URL of the desired image. You could even specify the .png URL you indicated in the question, like this:

Using app-drawer-layout with app-header-layout

I am creating a new webapp in Polymer 1.0 which needs the following layout.
A header panel which covers the entire page while loading and condenses to the height of a small toolbar
A responsive drawer panel which is swipeable in case of mobiles and gets persistent on large screens.
The polymer already had its own web components for this purpose namely,
app-header-panel and app-drawer-panel
I guess the straight forward solution is by containing the entire drawer panel within the header panel. They worked perfect until I put both of them together in a single page. I'm facing some layout issues when using them together.
The persistent drawer moving behind the app-header-panel instead of sticking to the content area of the header panel. (NOTE: The app-header-layout has higher z-index than app-drawer-panel).
How to solve this issue?
First: clear all your css that tries to change the z-index or postion or anything else like these of any component of app-layout or it's going to mess up the component.
Here's my sample:
<app-drawer-layout fullbleed
force-narrow>
<!-- Drawer content -->
<app-drawer id="appDrawer"
swipe-open>
<app-toolbar>Menu</app-toolbar>
<!-- Some content -->
</app-drawer>
<!-- Main content -->
<app-header-layout has-scrolling-region>
<app-header fixed
effects="waterfall">
<app-toolbar>
<paper-icon-button icon="menu"
drawer-toggle></paper-icon-button>
<div title>My App</div>
</app-toolbar>
</app-header>
<!-- Some content -->
</app-header-layout>
</app-drawer-layout>
Do not forget to import all dependencies:

Getting Started with Polymer's Paper Elements

I've been playing with Polymer. I've successfully built a "hello world" app. My app includes the iron-elements. I'm now trying to integrate the paper-elements. Unfortunately, I can't seem to get them to work in my project.
I installed them via bower install PolymerElements/paper-elements. I then imported the .html similar to the way I did for the iron elements. However, the items didn't appear. So, I decided to take a step back and just do a "hello world" with the paper elements. To my surprise, I couldn't figure out how to just display a Button with Paper. Surely I'm not this dumb.
I sought out a basic app I could pull from GitHub and use. However, I didn't have any luck doing that either. Currently, I have the following:
<html>
<head>
<title>Hello</title>
<script src="res/packages/webcomponentsjs/webcomponents-lite.min.js"></script>
<!-- Polymer -->
<link rel="import" href="res/packages/polymer/polymer.html">
<!-- Paper Elements -->
<link rel="import" href="res/packages/font-roboto/roboto.html">
<link rel="import" href="res/packages/paper-header-panel/paper-header-panel.html">
<link rel="import" href="res/packages/paper-toolbar/paper-toolbar.html">
<link rel="import" href="res/packages/paper-button/paper-button.html">
<!-- End of Paper Elements -->
<!-- End of Polymer -->
</head>
<body unresolved>
<h1>Hello</h1>
<paper-header-panel>
<paper-button raisedButton label="button"></paper-button>
</paper-header-panel>
</body>
</html>
what am I doing wrong? Can someone either tell me what I'm missing or point me to a basic "hello world" app with Paper?
Thank you!
Remove your paper-header-panel and try this:
<paper-button raised>Raised button</paper-button>

polymer not working or displaying no elements

Trying to display hello world using elements but nothing happens any help?
index.html
<!DOCTYPE html>
<html>
<head>
<meta name="viewport"
content="width=device-width, minimum-scale=1.0, initial-scale=1.0, user-scalable=yes">
<script src="bower_components/webcomponentsjs/webcomponents.js"></script>
<link rel="import" href="elements/hello-world.html">

hello-world.html
<link rel="import" href="../bower_components/polymer/polymer.html">
<polymer-element name="hello-world" nonscript>
<template>
<h2>Hello World</h2>
</template>
</polymer-element>
Code for "hello-world.html" is now:
<link rel="import" href="../bower_components/polymer/polymer.html">
<dom-module id="hello-world">
<template>
<h1>Hello World</h1>
</template>
<script>
Polymer ({ is: "hello-world", });
</script>
</dom-module>
If you are using polymer version 0.8 or 0.9, then <polymer-element ... should be <dom-module ...
See more from polymer site:
https://www.polymer-project.org/0.9/docs/start/quick-tour.html
You have a typo, nonscript needs to be noscript.
<polymer-element name="hello-world" noscript>
I have the same problem and dont find the mistake.

<polymer-element name="hello" noscript>

<h1>Hello Polymer world</h1>
</template>
</polymer-element>
My platfrom is:
Win 8.1
nodejs
bower
polymer (installed over bower, folders and files are availible)
git
netbeans dev edition (as editor)
xammp (as apache webserver)
tested with chrome, firefox and ie10 and the custom element is not be shown. i don't think it's a browser problem. it's the simpliest element you can write, but why did it not work?
Edit:
tested it on a clean ubuntu installation. and it still does not work?
i also tested original code from the polymer page and this won't work too.
am i to stupid for copy paste?
Edit 2:
i found it an have running my polymer apps. If i use Polymer 1.0.9 i should not read the tutorial for 0.5.0
changes:
index.html:
<!DOCTYPE html>
<html>
<head>
...
<script scr="bower_components/webcomponents-lite.min.js"></script>
<!-- the lite edition is needet since polymer version 0.8 -->
<link rel="import" href="hello/hello.html">
...
</head>
<body>
<hello></hello>
</body>
</html>
hello/hello.html:
<link rel="import" href="../bower_components/polymer/polymer.html">
<dom-module id="hello">
<!-- its not longer a polymer-element. we have to use dom-module and id and the noscript option is not longer supported -->
<template>
<template>
<script>
// everytime you need to initialize a Polymer object
Polymer({
is: 'hello' // must be set now
});
</script>
</dom-module>
if you want to work with parameters you need to set it in the polymer ready function and every placeholder must be surrounded by a html tag like span without any other content in it.
Replace the line
<script src="bower_components/webcomponentsjs/webcomponents.js"></script>
with
<script src="../bower_components/webcomponentsjs/webcomponents.js"></script>
This should fix the issue.

Polymer: perform animated-pages transition on polymer element

Say I've got one polymer app test-app, one regular div div-a, and one polymer element page-a.
Now I'm trying to build a animated-pages, which contains div-a and page-a
<link rel="import" href="../../bower_components/core-header-panel/core-header-panel.html">
<link rel="import" href="../../bower_components/core-icons/core-icons.html">
<link rel="import" href="../../bower_components/paper-icon-button/paper-icon-button.html">
<link rel="import" href="../../bower_components/core-animated-pages/core-animated-pages.html">
<link rel="import" href="../page-a/page-a.html">
<polymer-element name="test-app" flex vertical layout>
<template>
<core-animated-pages
selected="{{selected}}"
transitions="cross-fade"
>
<section name="div-a">
<div cross-fade>
<span>div-a</span>
</div>
</section>
<section name="page-a">
<page-a cross-fade></page-a>
</section>
</core-animated-pages>
</template>
<script src="./test-app.js"></script>
</polymer-element>
The problem is: when performing the transition, the animation on div-a works fine, but the one on page-a doesnot work. Instead of fading in, the page-a just suddenly appears.
Another strange point is: if I change transitions="cross-fade" into transitions="cross-fade-all", and remove other cross-fade defined on div and page-a, both transitions work find.
Any idea?
Cross-fade doesn't work directly on elements that have overflow: hidden set.
