Conditional heading color using uib-accordion

I am using angular-ui with my angularjs application. I have an accordion (uib-accordion) element on my page. Its content, name and state (opened/closed) are bind to an array in the controller.
I want to achieve the following behavior: when the tab is closed, the heading should be gray. When it is opened, it should be another color. How can I do that, based on the value of filter.isOpened? I tried with ng-class something like:
ng-class="{'panel-blue-heading': filter.isOpened}"
but I did not manage to do it. Below is a simple fiddle, maybe it helps.
Thanks!
var app = angular.module("myApp", ['ui.bootstrap']);
app.controller('testCtrl', ['$scope', function($scope) {
$scope.filtersInfo = [{
filterParams: [1, 2, 3, 4],
filterName: "testFilter",
isOpened: true
}];
}]);
.panel-default {
border: 0;
}
.panel-group {
margin-bottom: 5px;
}
.panel-body {
padding: 5px;
}
.panel-default >.panel-heading {
color: black;
}
.panel-blue-heading >.panel-heading {
background-color: #42c6eb;
color: black;
}
.container {
padding: 10px;
border-radius: 15px;
border: 1px solid black;
}

You were almost there:
<uib-accordion close-others="oneAtATime" ng-class="{'opened': filter.isOpened}" id="my-accordion">
Then in your CSS, target the .panel-heading that is created by the directive:
#my-accordion.opened .panel-heading {
background-color: blue;
}
I add the ID so as not affect any other panel headings that were not intended to have a blue background.
var app = angular.module("myApp", ['ui.bootstrap']);
app.controller('testCtrl', ['$scope', function($scope) {
$scope.filtersInfo = [{
filterParams: [1, 2, 3, 4],
filterName: "testFilter",
isOpened: true

Just clear this code where you wrote:
md-chip {

}
Here CodePen example

Add canvas to fullpage.js

I'm trying to add a WebGL-script to a site with FullPage.js but it doesn't work so well (I just get a black screen). I have no idea what the problem is since both the WebGL-script and Fullpage.js work perfect separately. I was not able to add all the script to a jsFiddle but the scripts can be seen at this site http://www.scandinavija.com/index.html (I removed all the non-relevant script).
When I inspect the site in Chrome I get the following error: "Uncaught TypeError: Cannot read property 'offsetWidth' of null at particles.js:6" May that be the problem?
My instinct, however, rather tells me that the problem should be somewhere here:

You get this error because you try to access a property of an object that is evaluated to null.
particles.js
var container = document.getElementById('canvas-container');
// ^^^^^^^^^^^^^^^^
// not found
var w = container.offsetWidth;
// ^^^^^^^^^
// eq. null
This is because your element #canvas-container doesn't exists in the DOM when the script particles.js is executed.
You just have to wrap your code inside a document loaded callback to ensure the element will be accessible :
$(function() {
// particles.js code
});
You can also simply move your script tag at the end of your HTML file :
...
<script type="text/javascript" src="js/particles.js"></script>

Polymer paper-header-panel not showing any content in paper-drawer-panel

When I run my code I can only see the STANDARD TEST paper-header-panel.
Everything within paper-drawer-panel seems to be hidden.
If I set the initial paper-header-panel(class=blue) to 1000px, The rest of the content will show.
Is there anything I need to set so the initial paper-header-panel will change it's height automatically based on the content?
Thanks

Nevermind. I figured out the problem.
The issue was being caused by the HTML DOCTYPE
After removing it. Everything is now working correctly.

Unable to apply core-animated pages transition with JS

I've been getting an error while trying to apply a core-animated-pages element, with polymer, to my element.
I've searched the code for errors, missing linking elements, missing imports, styles, and found nothing.
The idea is for a small app that once you click on the login button, shown in a customized login box, it will change the section where the login is to a new one.
Here is my code:

I see you are importing slide-from-right.html, but you then use transitions="fade-scale" (which is not defined as a core-animated-pages transition). You instead need to import each transition you wish to use, and separate them by spaces in the transitions list:
<link rel="import" href="components/core-animated-pages/transitions/cross-fade.html">,
<link rel="import" href="components/core-animated-pages/transitions/scale-up.html">,
...
<core-animated-pages selected="{{ sel }}" transitions="cross-fade scale-up">
