通过调整图片透明度,结合animation,实现图片呼吸效果
.circle{
/* 不透明度 */
opacity: 1;
/* 动画名称 */
animation-name: breath;
/* 动画时长3秒 */
animation-duration: 1200ms;
/* 动画速度曲线:以低速开始和结束 */
animation-timing-function: ease-in-out;
/* 播放次数:无限 */
animation-iteration-count: infinite;
/* Safari and Chrome */
/* 动画名称 */
-webkit-animation-name: breath;
/* 动画时长3秒 */
-webkit-animation-duration: 1200ms;
/* 动画速度曲线:以低速开始和结束 */
-webkit-animation-timing-function: ease-in-out;
/* 播放次数:无限 */
-webkit-animation-iteration-count: infinite;
}
/* 1.图标呼吸 */
@keyframes breath {
from {
opacity: 1;
}
/* 动画开始时的不透明度 */
/* 50% { */
/* opacity: 0.8; */
/* } 动画50% 时的不透明度 */
to {
opacity: 0.7;
}
/* 动画结束时的不透明度 */
}
@-webkit-keyframes breath {
from {
opacity: 1;
}
/* 动画开始时的不透明度 */
/* 50% { */
/* opacity: 0.8; */
/* } 动画50% 时的不透明度 */
to {
opacity: 0.7;
}
/* 动画结束时的不透明度 */
}
效果图:(PS:锤子透明度不变 呼吸的是锤子下面的圈)
透明度为1:
透明度为0.7:
// 圈旋转动画
@keyframes circleRotate {
50% {
transform: rotate(180deg);
opacity: 1;
}
100% {
transform: rotate(360deg);
opacity: 1;
}
}
