How can I avoid embedding css files to output html files during pub build (generate js)? Is it possible?
note: polymer version is 0.10.0-pre.11
Before pub build:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Sample app</title>
<link rel="stylesheet" href="cc.css">
<link rel="import" href="packages/polymer/polymer.html">
<!-- import the click-counter -->
<link rel="import" href="clickcounter.html">
<script type="application/dart">export 'package:polymer/init.dart';</script>
<script src="packages/browser/dart.js"></script>
</head>
<body>
<h1>Cc</h1>
<p>Hello world from Dart!</p>
<div id="sample_container_id">
<click-counter count="5"></click-counter>
</div>
</body>
</html>
After pub build:
<!DOCTYPE html><html><head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Sample app</title>
<!-- import the click-counter -->
</head>
<body><style>body {

font-family: 'Open Sans', sans-serif;
font-size: 14px;

margin: 15px;
}
h1, p {

}
#sample_container_id {

height: 400px;

As you can see the css file is embedded to html..
Work around for this issue is to add to every element #import ('mystle.css')
eg.
<my-element name="my-element">
<template>
<style>#import ('mystyle.css')</style>
...
</template>
<my-element>

Update
In Polymer.dart 0.12.1 an option was added to disable style inlining per file - see https://github.com/dart-lang/polymer-dart/blob/master/CHANGELOG.md#0121

Can anyone help me????
I have problems to set elements draggable using jQueryUI 1.12.1.
There is no problem, when draggable element is <div>, but when I switched it to the <input ... >, it does not move from place. I tried to disable element too in order to make it more "stiff", but it makes no difference.
The similarly pitiful outcomes I had with resizing <label> for <input>. I could move it on the screen, but I was unable to resize it.
Here is code I just copied from the page and made minor changes:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>resizable demo</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css">
<style>
#brick {
width: 100px;
height: 100px;
background: #ccc;
} </style>
<script src="http://code.jquery.com/jquery-1.12.4.js"></script>
<script src="http://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<label id="brickLabel" for="brick">Brick is stiff</label>
<input type='text' id="brick" disabled/>
<div id="goodBrick" style="width: 100px; height: 70px; background-color: #EF45fE"></div>
<script>
$( "#goodBrick" ).draggable();
$( "#goodBrick" ).resizable();
$( "#brick" ).draggable();
$( "#brick" ).resizable();
$( "#brickLabel" ).draggable();
$( "#brickLabel" ).resizable();

So where I do mistake?
I use dart-polymer package to create custom elements. I have noticed that there is some blinking during of page with the custom elements loading. This effect also is visible for the very simple ClickCounter app. Is there any way to avoid this vexing blinking?
The issue is good described in Wikipedia http://en.wikipedia.org/wiki/Flash_of_unstyled_content
The suggested solution from http://www.polymer-project.org/docs/polymer/styling.html#fouc-prevention does not work for the simple application (polymer: '0.10.0-pre.2')..

Polymer 0.9.5
The class names to use are polymer-veiled (hidden) and polymer-unveil (during unveil transition)
If it is different than in Polymer.js it is probably subject of change but as of PolymerDart 0.9.0 it should work.
The relevant code is in packages/polymer/src/boot.dart.
Polymer 0.10.0
Polymer 0.10.0-pre.1 uses already the unresolved attribute like explained here
Polymer - Styling reference - FOUC prevention
You need to add a version constraint in pubspec.yaml to get the development version like
polymer: ">=0.10.0-pre.1"
I'm trying to style distributed nodes in Dart Polymer with no luck. I'm using the example at:
http://www.polymer-project.org/articles/styling-elements.html#style-distributed
as a starting point. However, I can't even get that working once ported to Dart. Here is my code:
<polymer-element name="test-element">
<template>
<style>
content[select="p"]::content * { /* anything distributed here */
font-weight: bold;
}
/* #polyfill p:first-child */
::content p:first-child {
color: red;
}
/* #polyfill footer > p */
::content footer > p {
color: green;
}
/* #polyfill :host > p */
::content > p { /* scope relative selector */
color: blue;
}
</style>
<content select="p"></content>
<content></content>
</template>
<script type="application/dart" src="testelement.dart"></script>
</polymer-element>
.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Sample app</title>
<link rel="stylesheet" href="testpolymer.css">
<!-- import the test-element -->
<link rel="import" href="testelement.html">
<script type="application/dart">export 'package:polymer/init.dart';</script>
<script src="packages/browser/dart.js"></script>
</head>
<body>
<h1>TestPolymer</h1>
<p>Hello world from Dart!</p>
<test-element>
<p>I'm red and bold</p>
<p>I'm blue and bold</p>
<footer>
<p>I'm also red</p>
<p>I'm green</p>
<span>I'm black</span>
</footer>
</test-element>
</body>
</html>
The output has no styling applied and is just black text for everything. Any ideas what I'm doing wrong?
polymer-elements polymer-flex-layout / polymer-flex-layout.css still use
::-webkit-distributed(p) {
color: red;
}
which also works in my recent version of Dartium.
I have no idea when the new selectors take effect.
Other polymer-elements that make use of this selector but have recently switched to ::content
polymer-ui-field
polymer-ui-menu-item
polymer-ui-nav-arrow
polymer-ui-pages
polymer-ui-sidebar
polymer-ui-toolbar
You can browse the history to find the previous webkit-distributed selector examples.
I guess they use Chromium which may be a little ahead of Dartium.
I have a problem that the text inside the content-div is scrollable. Happens on iOS 6 with iPhone 4 and only if native title is set.

forge.logging.log("Topbar image error: " + e);
});

<div data-role="page">
<div data-role="content">

You might want to try to reset all the margins, paddings and border for all elements using CSS. Add this right before the closing </head>:
<style type="text/css">
* { /* reset */
margin: 0;
padding: 0;
border: 0;
}
</style>
