| <h1>Transform Style</h1> |
| <p>This example shows the effect of <code>-webkit-transform-style</code>. The blue box has perspective set on it. |
| The purple box has |
| <pre> |
| -webkit-transform-style: preserve-3d; |
| </pre> |
| <p>which allows the yellow and green boxes to live in a shared 3D space, and thus appear to stand away |
| from the purple box by virtue of their transforms. |
| </p> |
| <p> |
| However, when you hover, we set the purple box to: |
| </p> |
| <pre> |
| -webkit-transform-style: flat; |
| </pre> |
| <p>so its children collapse into it. Their <code>-webkit-transform</code> still applies, but now |
| it's just a painting effect, and is not affected by the container's perspective. |
