一、css动画(animation)属性可以逐渐地从一个值变化到另一个值,比如尺寸大小、数量、百分比、位置和颜色。
二、实现方法:
1.定义动画(slideOut为自定义的动画名称)
@-webkit-keyframes slideOut{ 0%{top:-30px; opacity: 0;} 100%{top:0px; opacity: 1;} } @-moz-keyframes slideOut{ 0%{top:-30px; opacity: 0;} 100%{top:0px; opacity: 1;} } @-o-keyframes slideOut{ 0%{top:-30px; opacity: 0;} 100%{top:0px; opacity: 1;} } @-ms-keyframes slideOut{ 0%{top:-30px; opacity: 0;} 100%{top:0px; opacity: 1;} } @keyframes slideOut{ 0%{top:-30px; opacity: 0;} 100%{top:0px; opacity: 1;} }
2、调用动画
-webkit-animation: slideOut 0.5s ease-in-out 0.3s backwards; -moz-animation: slideOut 0.5s ease-in-out 0.3s backwards; -o-animation: slideOut 0.5s ease-in-out 0.3s backwards; -ms-animation: slideOut 0.5s ease-in-out 0.3s backwards; animation: slideOut 0.5s ease-in-out 0.3s backwards;
三、动画用到的属性有background/border/border/box-shadow/clip/color/column/filter/flex/font/letter-spacing/line-height/margin/opacity/outline/perspective/text/vertical-align/visibility/word-spacing/z-index等等,基本上所以元素了。
