css3 transform-origin issue in 3D cube - html

Question

I have created css-cube and its rotating on :hover.
But Its rotation is based on one side of cube!
I want to rotate it from its center, like in this example. I was trying transform-origin property but not got desired result.
I have also tried placing one middle plane inside cube but hover is not working in that situation!
.contain {
width: 300px;
height: 300px;
-webkit-perspective: 500px;
perspective: 500px;
position: absolute;
}
.main {
position:relative;
width:100px;
height:100px;
margin:100px 100px;
background:#07a;
overflow:visible;
transition: all linear,transform cubic-bezier(0.4, 0.25, 0.14, 1.5),background cubic-bezier(0.4, 0.25, 0.14, 1.5);
transition-duration: 700ms;
-moz-transform-style: preserve-3d;
-webkit-transform-style: preserve-3d;
transform-style: preserve-3d;
transform-origin: center center;
}
.main:hover{
transform:rotateY(180deg);
}
.top, .right, .left, .bottom,.lid{
position:absolute;
width:100px;
height:100px;
z-indexd:999;
transition: all 1s ease;
}
.top {
background:crimson;
top:-100px;
transform-origin : 50% 100%;
transform:rotateX(-90deg);
}
.bottom {
background:crimson;
bottom:-100px;
transform-origin :100% 0%;
transform:rotateX(90deg);
}
.left {
background:#ccc;
left:-100px;
transform-origin :100% 0%;
transform:rotateY(90deg);
}
.right {
background:#ccc;
right:-100px;
transform-origin : 0% 0%;
transform:rotateY(-90deg);
}
.lid {
background:#07a;
transform: translateZ(170px);
transform-origin : 0% 0%;
transform:translateZ(100px);
}
<div class="contain">
<div class="main">
<div class="lid"></div>
<div class="top"></div>
<div class="right"></div>
<div class="left"></div>
<div class="bottom"></div>

Answer 1

The problem is that you need to set the transform origin in the center of the cube, and the cube is a 3d element. You are missing the 3rd dimension !
So it should be
transform-origin: center center 50px;
since your cube side is 100px
.contain {
width: 300px;
height: 300px;
-webkit-perspective: 500px;
perspective: 500px;
position: absolute;
}
.main {
position:relative;
width:100px;
height:100px;
margin:100px 100px;
background:#07a;
overflow:visible;
transition: all linear,transform cubic-bezier(0.4, 0.25, 0.14, 1.5),background cubic-bezier(0.4, 0.25, 0.14, 1.5);
transition-duration: 700ms;
-moz-transform-style: preserve-3d;
-webkit-transform-style: preserve-3d;
transform-style: preserve-3d;
transform-origin: center center 50px;
}
.main:hover{
transform:rotateY(180deg);
}
.top, .right, .left, .bottom,.lid{
position:absolute;
width:100px;
height:100px;
z-indexd:999;
transition: all 1s ease;
}
.top {
background:crimson;
top:-100px;
transform-origin : 50% 100%;
transform:rotateX(-90deg);
}
.bottom {
background:crimson;
bottom:-100px;
transform-origin :100% 0%;
transform:rotateX(90deg);
}
.left {
background:#ccc;
left:-100px;
transform-origin :100% 0%;
transform:rotateY(90deg);
}
.right {
background:#ccc;
right:-100px;
transform-origin : 0% 0%;
transform:rotateY(-90deg);
}
.lid {
background:#07a;
transform: translateZ(170px);
transform-origin : 0% 0%;
transform:translateZ(100px);
}
<div class="contain">
<div class="main">
<div class="lid"></div>
<div class="top"></div>
<div class="right"></div>
<div class="left"></div>
<div class="bottom"></div>
</div>
</div>

Answer 2

I added a translateZ to move the rotation axis, it looks a little more centered but still not like Desandro's ex.,
I read the documentation and I think you should checkout this! it explains a little bit about orgins and perspectives...
EDIT1:
integrated translateZ instead of transform origin (now it's perfect!!)
.contain {
width: 300px;
height: 300px;
-webkit-perspective:666px;
perspective: 666px;
position: absolute;
}
.main {
position:relative;
width:100px;
height:100px;
margin:100px 100px;
background:#07a;
overflow:visible;
transition: all 1s ease;
-moz-transform-style: preserve-3d;
-webkit-transform-style: preserve-3d;
transform-style: preserve-3d;
transform:translateZ(-50px)
}
.main:hover{
transform: translateZ(-50px) rotateY(180deg);
}
.top, .right, .left, .bottom,.lid,.front{
position:absolute;
width:100px;
height:100px;
z-index:999;
transition: all 1s ease;
}
.front{
background:yellow;
transform:rotateY( 0deg ) translateZ( 50px );
}
.left {
background:red;
transform:rotateY(90deg) translateZ( 50px );
}
.right {
background:purple;
right:-100px;
//transform-origin : 0% 0%;
transform:rotateY(-90deg) translateZ( 150px );
}
.lid {
background:green;
transform:rotateY(180deg) translateZ( 50px );
}
<div class="contain">
<div class="main">
<div class="front"></div>
<div class="lid"></div>
<div class="right"></div>
<div class="left"></div>
</div>
</div>
BTW CSS-transformations rock!!

Answer 3

I tried Adding "translateZ(-70px)" in the ".main:hover" and I think it's rotating centered.
With this will make when your cube is rotating make the translate some pixels to left and make feeling it's centered.
