| 15 | |
| 16 `core-animation-group` combines `core-animation` or `core-animation-group` eleme
nts to | |
| 17 create a grouped web animation. The group may be parallel (type is `par`) or seq
uential | |
| 18 (type is `seq`). Parallel groups play all the children elements simultaneously,
and | |
| 19 sequential groups play the children one after another. | |
| 20 | |
| 21 Example of an animation group to rotate and then fade an element: | |
| 22 | |
| 23 <core-animation-group type="seq"> | |
| 24 <core-animation id="fadeout" duration="500"> | |
| 25 <core-animation-keyframe> | |
| 26 <core-animation-prop name="transform" value="rotate(0deg)"></core-anim
ation-prop> | |
| 27 <core-animation-prop name="transform" value="rotate(45deg)"></core-ani
mation-prop> | |
| 28 </core-animation-keyframe> | |
| 29 </core-animation> | |
| 30 <core-animation id="fadeout" duration="500"> | |
| 31 <core-animation-keyframe> | |
| 32 <core-animation-prop name="opacity" value="1"></core-animation-prop> | |
| 33 </core-animation-keyframe> | |
| 34 <core-animation-keyframe> | |
| 35 <core-animation-prop name="opacity" value="0"></core-animation-prop> | |
