实现效果
X轴Y轴在一个矩形内移动
做斜线运动
.ball { position: absolute; animation: animX 2s linear infinite alternate, animY 2s linear infinite alternate } @keyframes animX{ 0% {left: 0px;} 100% {left: 500px;} } @keyframes animY{ 0% {top: 0px;} 100% {top: 300px;} }
设置动画延时
设置Y轴延时为动画时长的一半, 运动轨迹变成菱形
.ball { animation: animX 2s linear 0s infinite alternate, animY 2s linear -1s infinite alternate }
设置三次贝塞尔曲线
.ball { animation: animX 2s cubic-bezier(0.36, 0, 0.64, 1) -1s infinite alternate, animY 2s cubic-bezier(0.36, 0, 0.64, 1) 0s infinite alternate }东莞vi设计https://www.houdianzi.com/dgvi/ 豌豆资源网站大全https://55wd.com
缩小放大
为了看起来有立体感添加scale属性,scale动画应该是X轴和Y轴的时间总和
.ball1 { animation: animX 2s cubic-bezier(0.36, 0, 0.64, 1) -1s infinite alternate, animY 2s cubic-bezier(0.36, 0, 0.64, 1) 0s infinite alternate, scale 4s cubic-bezier(0.36, 0, 0.64, 1) 0s infinite alternate; } @keyframes scale { 0% { transform: scale(0.7) } 50% { transform: scale(1) } 100% { transform: scale(0.7) } }
