这一节,自学CSS动画。主要学习了淡入淡出、淡入缩放、缩放、移动、旋转动画效果。先看一下成果。
优雅的过渡动画,为你的页面添加另一份趣味! 在你的选择器里插入 animation 属性,并添加框架内置的 @keyframes 即可实现!
一、CSS代码
/* 旋转 */
@keyframes rotate{ from{ transform: rotate(0deg) } to{ transform: rotate(360deg) } }
@-webkit-keyframes rotate{ from{ transform: rotate(0deg) } to{ transform: rotate(360deg) } }
/*淡入淡出*/
@keyframes fade-in{ from{ opacity: 0 } to{ opacity: 1 } }
@-webkit-keyframes fade-in{ from{ opacity: 0 } to{ opacity: 1 } }
@keyframes fade-off{ from{ opacity: 1 } to{ opacity: 0 } }
@-webkit-keyframes fade-off{ from{ opacity: 1 } to{ opacity: 0 } }
@keyframes fade-in-top{ from{ opacity: 0; transform: translateY(20px) } to{ opacity: 1; transform: translateY(0) } }
@-webkit-keyframes fade-in-top{ from{ opacity: 0; transform: translateY(20px) } to{ opacity: 1; transform: translateY(0) } }
@keyframes fade-in-bottom{ from{ opacity: 0; transform: translateY(-20px) } to{ opacity: 1; transform: translateY(0) } }
@-webkit-keyframes fade-in-bottom{ from{ opacity: 0; transform: translateY(-20px) } to{ opacity: 1; transform: translateY(0) } }
@keyframes fade-in-left{ from{ opacity: 0; transform: translateX(20px) } to{ opacity: 1; transform: translateX(0) } }
@-webkit-keyframes fade-in-left{ from{ opacity: 0; transform: translateX(20px) } to{ opacity: 1; transform: translateX(0) } }
@keyframes fade-in-right{ from{ opacity: 0; transform: translateX(-20px) } to{ opacity: 1; transform: translateX(0) } }
@-webkit-keyframes fade-in-right{ from{ opacity: 0; transform: translateX(-20px) } to{ opacity: 1; transform: translateX(0) } }
/*淡入缩放*/
@keyframes fade-small-large{ from{ opacity: 0; transform: scale(.5, .5) } to{ opacity: 1; transform: scale(1, 1) } }
@-webkit-keyframes fade-small-large{ from{ opacity: 0; transform: scale(.5, .5) } to{ opacity: 1; transform: scale(1, 1) } }
@keyframes fade-large-small{ from{ opacity: 1; transform: scale(1, 1) } to{ opacity: 0; transform: scale(.5, .5) } }
@-webkit-keyframes fade-large-small{ from{ opacity: 1; transform: scale(1, 1) } to{ opacity: 0; transform: scale(.5, .5) } }
@keyframes fade-larger-small{ from{ opacity: 0; transform: scale(1.5, 1.5) } to{ opacity: 1; transform: scale(1, 1) } }
@-webkit-keyframes fade-larger-small{ from{ opacity: 0; transform: scale(1.5, 1.5) } to{ opacity: 1; transform: scale(1, 1) } }
@keyframes fade-small-larger{ from{ opacity: 1; transform: scale(1, 1) } to{ opacity: 0; transform: scale(1.5, 1.5) } }
@-webkit-keyframes fade-small-larger{ from{ opacity: 1; transform: scale(1, 1) } to{ opacity: 0; transform: scale(1.5, 1.5) } }
@keyframes scale-small-large{ from{ transform: scale(0, 0) } to{ transform: scale(1, 1) } }
@-webkit-keyframes scale-small-large{ from{ transform: scale(0, 0) } to{ transform: scale(1, 1) } }
@keyframes scale-large-small{ from{ transform: scale(1, 1) } to{ transform: scale(0, 0) } }
@-webkit-keyframes scale-large-small{ from{ transform: scale(1, 1) } to{ transform: scale(0, 0) } }
/*移动动画*/
@keyframes up-and-down{ from{ transform: translateY(-20px) } to{ transform: translateY(20px) } }
@-webkit-keyframes up-and-down{ from{ transform: translateY(-20px) } to{ transform: translateY(20px) } }
@keyframes left-and-right{ from{ transform: translateX(-20px) } to{ transform: translateX(20px) } }
@-webkit-keyframes left-and-right{ from{ transform: translateX(-20px) } to{ transform: translateX(20px) } }
