I've included an inline svg in the html. My goal is to identify the individual stars and apply a "twinkle" effect as a keyframe.
I noticed there are inline style attributes for its transform properties.
I changed the transform-origin of the individual star, #star to transform-origin: 50% 50% and added a transform: scale(1.2), just to test a simple scaling effect.
For some reason, I don't see the transform being applied when I hover over #star element. The star disappears on hover.
Heres a link to my codepen
Apply the transform:scale() to #star:hover polygon this should change the size of the polygons within the group.
#star:hover polygon{
transform: scale(1.2)
}

What's wrong with my CSS3 newbie animation? It won't go all the way across the screen even when I set it to from 0px, to 100%.

Unfortunately the image won't show up but you can see the fallback text moving to get the gist of what's wrong.
<object id="pandaMove" data="http://svgshare.com/i/gY.svg" type="image/svg+xml">This is an image</object>
to {transform: translateX(100%);} in the keyframe rules makes the svg container move by 100% of it's own width, not that of the parent element...
If you know the width of the svg element, you can use this type of rule (in my example the width would be 320px):
#keyframes pandaRight {
from {left: 0px;}
to {left: calc(100% - 320px);}
}

I am trying to animate svg path object with css animation. My goal is to animate CSS property transform: translateX(0%) to transform: translateX(50%). Please check jsFiddle.
Two things here:
Notice, SVG path object width is 2 times larger than parent SVG.
If you change percentage in CSS to px, animation is running as expected.
I want to create this triangle in CSS.
http://acceptatie.foursites.nl/foursites/vierkant.jpg
But it must be a fluid triangle. How can i make this I try with skewY. But than the triangle is broken at the to of the element.
Thank you for helping me!
Instead of using borders to make the triangle you can use transform to rotate a div and just hide the overflow of the parent element.
If use transform instead of borders you can have box shadow on the div to :)
Tranform code for rotating a div
-webkit-transform: rotate(357deg);
-moz-transform: rotate(357deg);
-ms-transform: rotate(357deg);
-o-transform: rotate(357deg);
and as i said just hide the overflow on the parent element, in your case the body tag
overflow: hidden;
But here is an example on jsfiddle
Hope you can use it.
I have two absolutely positioned div elements that overlap. Both have set z-index values via css. I use the translate3d webkit transform to animate these elements off the screen, and then back onto the screen. After the transform, the elements no longer respect their set z-index values.
Can anyone explain what happens to the z-index / stack-order of the div elements once I do a webkit transform on them? And explain what I can do to keep the stack-order of the div elements?
Here is some more information on how I am doing the transform.
Before the transform, each element gets these two webkit transition values set via css (I am using jQuery to do the .css() function calls:
element.css({ '-webkit-transition-duration': duration + 's' });
element.css({ '-webkit-transition-property': '-webkit-transform' });
The element is then animated using the translate3d -webkit-transform:
element.css({ '-webkit-transform': 'translate3d(' + hwDelta + 'px, 0, -1px)' });
Btw, I have tried setting the 3rd parameter of translate3d to several different values to try to replicate the stack-order in the 3d space, but to no luck.
Also, iPhone/iPad and Android browsers are my target browser that this code needs to run on. Both support webkit transitions.
This might be related to: https://bugs.webkit.org/show_bug.cgi?id=61824
Basically when you apply a 3D transform on the z-axis, the z-index can't be accounted for anymore (you're now in a 3 dimensional rendering plane, use different z-values). If you want to switch back to 2D rendering for child elements, use transform-style: flat;.
This is most definitely related to the bug noted by samy-delux. This should only affect any elements which are positioned as absolute or relative. In order to remedy the issue, you can apply the following css statement to every element which is positioned this way and is causing issues:
-webkit-transform: translate3d(0,0,0);
This will apply the transform to the element without actually doing a transformation, but affecting its render order so it is above the element causing the issue.
Bit Late to this but try putting on the elements that have lost their Z-index placing the following, I had an issue when doing some parallax stuff recently and this helped massively.
transform-style: preserve-3d;
This saves putting
transform: translate3d(0,0,0);
On other elements which puts more strain on the GPU
Waiting to see the example
Have you tried to do a transform scale(1)? I remember to had a similar problem, and I had to re-arrange the html order of elements, and utilise a transform that I didn't need it just because the z-index of the use of transform changed.
If I am not in error, every time that you use a transform, it become the highest z-index available, and it is ordered by the nearest element of html is to the start of the tag. So from up to below.
I hope that this help
z-index will work against 3d transformed divs if you style the stackable element with -webkit-transform: translateZ(0px);
Snippet on codepen -> http://codepen.io/mrmoje/pen/yLIul
In the example, the buttons stack up and stack down raise and lower the footer's z-index (+/-1) against the rotated element (an img in this case).
I haven't been able to reproduce the problem you describe here. Regardless of what I do, the z-index value is retained throughout all transforms. I'm testing using Chromium (Google Chrome).
The third argument of the translate3d function manipulates the z-axis of the element. The concept is similar to, but not exactly the same as, the z-index... Elements with a lower z-axis are under elements with a higher value.
I know you tried values of the third argument to match your intended z-index, but the problem is that the z-axis doesn't seem to change during CSS3 animation. In the following example, the hovered element should be on top, but #element_a stays on top.
If I add a z-index to both the regular selector and the :hover selector, it seems to work and allow the hovered element to be top-most.
Although it's not exactly what you were looking for, this behavior provides a solution. You just need to use translate3d and z-index to set the order for the initial rendering.
<style>
div {
width: 300px;
height: 150px;
background-color: white;
border: 5px outset gray;
float: left;
margin: 20px;
-webkit-transition: 2s;
}
#element_a {
-webkit-transform: translate3d(0, 0, 50px);
}
#element_b {
-webkit-transform: translate3d(0, 0, 100px);
}
#element_a:hover {
-webkit-transform: translate3d(100px, 0, 60px);
}
#element_b:hover {
-webkit-transform: translate3d(-100px, 0, -60px);
}
</style>
<body>
<div id="element_a">
<img src="http://www.google.com/intl/en_com/images/srpr/logo3w.png">
</div>
<div id="element_b">
<img src="http://www.google.com/intl/en_com/images/srpr/logo3w.png">
</div>
</body>
I had this problem on iphone/ios where I had a dropdown menu that overlapped a leafletjs map but was being covered by the map. Noticed that the map had translate3d applied.
Added this to the dropdown element:
transform: translate3d(0,0,0);
...and it is fixed. Thank you stackoverflow people.
Another way around this is that you can create a parent element and apply all other transitions related to it:
# Apply transitions to a parent div
<div>
# This image z-index -1
<img src="foo"/>
# This image z-index -3
<img src="bar"/>
#This image z-index -2
<img src="gg"/>
</div>
