Webkit choking on rendering multiple text-shadow & box-shadow values with webkit-transition
CSS3 -webkit-transition is choking on multiple box-shadow values and text-shadow values. (Chrome & Safari)
More specifically, I have two scenarios...
I have text has a document heading that has three text-shadows (for appearance of depth). I am also using the -webkit-transition rule to change the color of the text-shadow on hover so that it appears to glow on hover.
I have links which I'm using the box-shadow rule on in the same way as above, with three values for depth effect. Also using -webkit-transition here to change the color of the buttons and text for a hover effect.
The Problem: For both instances above, when hovering over the elements webkit appears to render the transition as one at a time, so the values don't all fade into their new values simultaneously. Instead, they appear as each one is rendered - one after the other, and it is a very awkward transition as you'll see.
I have several instances, and here are links to some of them: (make sure to view in Chrome or Safari)
-Text-shadow transition on :hover for page h1 ("GIFT of HEALING" text): http://cure.org/goh
-Box-shadow transition on :hover for 1st slide call to action ("Read More" button): http://cure.org
-Box-shadow transition on :hover for footer nav links (About, Rods, etc): http://tuscaroratackle.com
Finally, here's a sample of the code I'm using: (Not from any site, just an example I built for this question; see it live here: http://joelglovier.com/test/webkit-shadow-transition-bug.html)
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
ul {
overflow:hidden;
width:500px;
height:auto;
margin:50px 100px;
background:rgba(0,0,0,.4);
border:1px solid rgba(0,0,0,1);
-webkit-border-radius:10px;
-webkit-box-shadow:inset 0px 0px 5px rgba(255,255,255,.5),0px 2px 10px #6e5e4c;
-webkit-transition:all .5s ease;
}
ul:hover {
-webkit-box-shadow:inset 0开发者_C百科px 0px 10px rgba(255,255,255,.5),0px 2px 10px #92d400;
}
li {
display:inline-block;
}
a:link,a:visited {
float:left;
display:block;
padding:6px 10px;
margin:10px 20px;
font:bold 18px/22px Tahoma,Helvetical,Arial,sans-serif;
text-decoration:none;
color:#000;
background:#92d400;
-webkit-border-radius:4px;
-webkit-box-shadow:inset 1px 1px 0px #b7f52f,0px 4px 0px #5c8500,0px 3px 10px #000;
-webkit-transition:all .5s ease;
}
a:hover,a:focus {
background:#198c45;
-webkit-box-shadow:inset 1px 1px 0px #1ac65c,0px 3px 0px #046228,0px 3px 10px #fff;
}
a:active {
position:relative;
top:1px
}
</style>
</head>
<body>
<ul>
<li><a href="#">link 1</a></li>
<li><a href="#">link 2</a></li>
</ul>
</body>
</html>
So the question here really is is there any way to prevent that ordered rendering, such as using different syntax in my CSS? (such as a specific order of the multiple box-shadow values, or using multiple box-shadow declarations instead of adding them all into one rule?)
05/09/2011 UPDATE: The bug has been reported to Webkit (see Husar's comment below). Also, I see that recent builds of Chrome (specifically my current 10.0.648.205 version) is rendering a smoothe transition now, effectively eliminating the bug. Safari however (version 5.0.5 (6533.21.1)) still displays the buggy rendering.
Apparently this is just a bug with webkit rendering, and there is no apparent fix.
I've also noticed that when you use jQuery, for example, to simply fade text in or out, WebKit "hiccups." So basically, I'm going to go out on a limb and say that I don't think your particular styles have anything to do with it. I could be completely wrong. If you find out what the deal is, I'd love to hear a solution because I too have run into this annoyance a time or two.
this could help to fix this problem on rendering for hovering events
-webkit-transform: translateZ(0px);
-moz-transform: translateZ(0px);
