Since Chrome Stable landed v.33.0.1750.117, the logic of window.getComputedStyle has changed from other browsers. Fiddle of code below: http://jsfiddle.net/HD4bD/17/
Can anyone explain what changed and what is the 'correct' ruling on this?
Given the following:
<body>
<div class="normal"></div>
<div class="display-none"></div>
<div class="visibility-hidden"></div>
</body>
.normal:before {
content: "NORMAL: "
}
.display-none:before {
content: "DISPLAY-NONE: ";
display: none;
}
.visibility-hidden:before {
content: "VIS-HIDDEN: "
visibility: hidden;
}
var $ = document.querySelector.bind(document),
pass = "This text should have 1 or more labels before it",
fail = "The label is missing. Something's wrong.",
normalContent = getB4Content('.normal'),
dNoneContent = getB4Content('.display-none'),
vHideContent = getB4Content('.visibility-hidden');
function getB4Content(selector){
return window.getComputedStyle($(selector),':before').getPropertyValue('content');
}
$('.normal').innerHTML = normalContent === '' ? fail : normalContent + pass;
$('.display-none').innerHTML = dNoneContent === '' ? fail : dNoneContent + pass;
$('.visibility-hidden').innerHTML = vHideContent === '' ? fail : vHideContent + pass;
Firefox v27:
NORMAL: "NORMAL: "This text should have 1 or more labels before it
"DISPLAY-NONE: "This text should have 1 or more labels before it
noneThis text should have 1 or more labels before it
IE 11
NORMAL: "NORMAL: "This text should have 1 or more labels before it
"DISPLAY-NONE: "This text should have 1 or more labels before it
noneThis text should have 1 or more labels before it
Chrome v33
NORMAL: "NORMAL: "This text should have 1 or more labels before it
The label is missing. Something's wrong.
The label is missing. Something's wrong.

It seems that this is a reported Chromium bug.
