#鸿蒙通关秘籍#如何实现动画的中间状态与过渡效果？

连续动画实现了组件从开始到结束之间平滑的过渡效果，包括中间状态的控制。在实现连续动画之前，通常需要定义animation-name和对应的@keyframes。以下是实现过程：

hml <div class="item-container"> <div class="item colorAnimation"> <text class="txt">color</text> </div> <div class="item opacityAnimation"> <text class="txt">opacity</text> </div> <input class="button" type="button" value="play animation" onclick="playAnimation"/> </div>

css .item-container { margin: 60px; flex-direction: column; }

.item { width: 80%; background-color: #f76160; }

.txt { text-align: center; width: 200px; height: 100px; }

.button { width: 200px; margin: 10px; font-size: 30px; background-color: #09ba07; }

.colorAnimation { animation-name: changeColor; animation-duration: 8s; animation-timing-function: ease-in-out; }

.opacityAnimation { animation-name: fadeOpacity; animation-duration: 8s; animation-timing-function: ease-in-out; }

@keyframes changeColor { from { background-color: #f76160; } to { background-color: #09ba07; } }

@keyframes fadeOpacity { from { opacity: 0.9; } to { opacity: 0.1; } }

通过为动画设置animation-timing-function，从而控制动画过渡过程中的速度曲线，以实现所需的视觉效果。
