CSS3 @keyframes simple animation implementation

Definition:

Animation can be created through @keyframes rules.

The principle of creating animation is to gradually change one set of CSS styles into another set of styles.

During the animation process, this set of CSS styles can be changed multiple times.

Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which are equivalent to 0% and 100%.

0% is the start time of the animation, 100% is the end time of the animation.

For best browser support, 0% and 100% selectors should always be defined.

Important: Compatibility issue! @keyfrmes Not compatible with IE 9 and earlier browsers.

Syntax:

@keyframes animationname {keyframes-selector {css-styles;}}
Copy after login
##css-stylesRequired. One or more legal CSS style properties.
@keyframes mymove
{
    0%   {top:0px;}
    25%  {top:200px;}
    75%  {top:50px}
    100% {top:100px;}
}

@-webkit-keyframes mymove /* Safari and Chrome */
{
    0%   {top:0px;}
    25%  {top:200px;}
    75%  {top:50px}
    100% {top:100px;}
}
//多个特性变化,用;隔开.

@-webkit-keyframes mymove{

0% {top:0px; left:0px; background:red;}
25% {top:0px; left:100px; background:blue;}
50% {top:100px; left:100px; background:yellow;}
75% {top:100px; left:0px; background:green;}
100% {top:0px; left:0px; background:red;}
}
