I've dropped in the code below but basically there's an element on the page. On hover transform: scale(1.2) is applied. The element has a transition on it. The main intention was that on transitionend some logic needed to be executed and so a transitionend event handler is attached. Now in all non Blink powered browsers is works absolutely fine. But in Chrome and Opera, if you keep moving the mouse, off the element, the event does not fire until you stop moving the mouse, despite the transition finishing some time ago. Anyone come across this before and have a solution?

I've got a simple Cycle2 slideshow that reads images from a server folder and displays them full height and centered on a web page. The images are loaded through an Ajax call which returns any new files it finds, it's called at page load and subsequently at programmed intervals. I use a session variable to keep track of the currently used files. I use the Cycle2 "add" command and the "Center" add-on as I have different sized images to display.
It works nicely except that after 'cycle' initialization any new slides added are not centered...
I know that Cycle2 adds inline styling but it only centers the images on initialization. It should be possible to call the centerHoriz and centerVert programatically when adding the new slides but can't work out how to at the same time as the 'add' command? Here is my code:
<?php

session_start();
$_SESSION['curfiles'] = array();

Question
How do I create a <paper-button> group UI element with the following characteristics?
It is a group of <paper-button> elements.
It is stacked vertically.
Each button fills the entire width of the container (without margin, padding or horizontal white space).
There is no margin, padding or vertical white space between the buttons.
Examples:
The effect I am seeking is analogous to <body fullbleed> only scoped to the button's parent container.
Similar to the Bootstrap "Vertical variation" shown here.
If you have Google Drive, hover your mouse over the menu items in the left margin of the page. (Under the red button labeled "New.")
Do a Google search. The dropdown menu that appears from the search field predictively suggesting possible questions you want is also another example of the look/feel I am after.
Attempts:
See below code for my previous attempts to:
stack vertical buttons using <p> tags and
use a <paper-menu>.

I'm super tired right now, will test an example tomorrow but I think theoretically all you'd have to do is:
<link href="bower/iron-flex-layout/iron-flex-layout.html" rel="import" >
<div class="layout vertical">
<paper-button>foo</paper-button>
<paper-button>foo</paper-button>
</div>
paper-button {
width: 100%;
margin:0;
}

I got my Vertical and Horizontal mixed up when i wrote this answer:)) so below is for horizontal Stacking. But thinking about its pretty much the same except for couple of changes.
So created a
.vertical-section {
min-width: 130px;
}
and make the buttons inline or flex;
eg
paper-button {
display: inline-block; //or inline-flex
margin-bottom: 24px;
}
To get rid of padding/margin etc see below because it should be the same
I played around with the Css for the paper-buttons demo so the above changes will work
For Horizontal stacking
Looking at the demo here paper-buttons and right click to view frame source the code goes like this
<style is="custom-style">
.horizontal-section {
min-width: 130px;
}
paper-button {
display: block;
margin-bottom: 24px;
}
</style>
<div>
<h4>Raised</h4>
<div class="horizontal-section">
<paper-button tabindex="0" raised>button</paper-button>
<paper-button tabindex="0" raised class="colorful">colorful</paper-button>
<paper-button tabindex="0" raised disabled>disabled</paper-button>
<paper-button tabindex="0" raised noink>noink</paper-button>
<paper-button tabindex="0" raised class="colorful custom"><iron-icon icon="check"></iron-icon>ok</paper-button>
<paper-button tabindex="0" raised class="custom"><iron-icon icon="clear"></iron-icon>cancel</paper-button>
</div>
</div>
</div>
That gives you something like this
Now as you dont want any margin/padding etc and fill the entire width you need to amend the css a bit and inspect the button element.
Take out the padding:24px; from the .horizontal-section eg padding:0;
And take out the paper-button:not margin-bottom:24px; and margin:0 0.25em; from paper-button css
and you end up with this
As you are using a template i beileve the styling may need to go before that.
Sorry i cant do you a demo, i managed to do a demo for someone in 0.5 but not yet for V.1 but its easy to understand the method above.

I have a popover functionality to be implemented in my project developed using ember js. I have a button, which when clicked should show a popover with a list of action menus.
I tried an example with bootstrap popover, which looks good to our cause, but I am unable to use that as we are not using bootstrap lib and don't want to include it only for this popover feature.
Is there any inbuilt support from ember js on the popover function yet (we are using ember v0.2.3)? I know it has a modal implementation but that will diable all other functions on the page until closed.
If you are aware of any custom popover impls that can be ported for trial, please let me know.
Thanks!
A nested component would be ideal for this. Rendering into an outlet like the modal examples doesn't make much sense to me.
You will need to handle a click event in your component's .js file.
Use a property on the component like isOpen to keep track of whether the popover should be shown or not.
Use an if isOpen in your component's template to control whether the child component (the popover) gets rendered or not.

I am using dynamic content (WordPress) and would like to center a logo in the middle of a list like: http://www.munto.net/queed-v1/.
I tested it out and my theory works, provided the number of items on both sides is the same...but if they're different it messes up the navigation.
You can see a live example at: http://joshrodgers.com/.
What I did was made my logo a background image and centered that to my unordered-list, then I set a width on each list-item (so that if there was a super-long one it wouldn't mess up the navigation), and finally after the third link I put a 200px margin on to the right of the list-item (that way there is no list-item over the logo)...but like I said this works perfectly if the number of items is even, if the items equal an odd number it looks funny.
Not sure what the best way to do this, so - what would be the best way to fix this?

From a design point of view i would maybe consider making the logo the home link. A lot of web users are accustomed to clicking the logo and it taking them home. You could still incorporate the home text underneath the logo.
I would probably not use your method of margin-right: 200px to not cover the logo, anything you change before that list item will shift the margin.
Ultimately i would suggest rethinking having the logo set as a background-image and make it one of the list items.
I am currently attempting to get a DIV to expand to 100% of the browser's height. I know that is a commonly asked question and so have read countless forums in order to find the answer but have yet to find something which will work across all browsers.
My CSS file looks something like this:
html{height:100%;}
body {
background: #ffffff;
font-size: 0.8em;
line-height: 1.7;
color: #09123e;
height:100%;
}
#wrapper {
background: #ffffff url(../images/assets/wrapper.bg.gif) repeat-y center center;
margin: 0 auto;
height:100%;
}
This renders as expected in all browsers except later versions of Internet Explorer, most notably IE7 and IE8. I have found that if I use min-height instead of height on #wrapper then I get the desired result in the problematic browsers but this then messes up the rendering in everything else. I have tried using a conditional stylesheet but the #wrapper style specified just seems to get ignored.
Any help would be greatly appreciated.
This works fine in all browsers, make sure you use doctype!
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<style type="text/css">
* {margin: 0px; padding: 0px;} //Reset all margins, use some css reset stylesheet instead...
html {height: 100%;}
body {height: 100%;}
#wrapper {
margin: 0 auto;
height: 100%;
}
</style>
</head>
<body>
<div id="wrapper"></div>
</body>
</html>
The only reliable solution to this problem that I've found is to use javascript/jquery to manually change the height. That is, assuming the visitor has javascript enabled. I have a site that has a colored side-menu bar and a white content area. Both are divs and one is float-right, and the other float-left. The content area is Almost always larger than the side menu bar, so to make the colored side bar as long as the content I use this little jQuery snippet.
<script language="javascript">
<!--
$(document).ready(function() {
var p = $( "#pageContent" ).height();
var m = $( "#menuContent" ).height();
if (m < p) $( "#menuContent" ).height( p );
});
-->
</script>
