Question

Hello Friends这是我的css代码。

.create_animation{
    width: 100%;
    height: 100%;
    overflow: hidden;
    background-image: url("animation/background.jpg"),url("animation/background.jpg");
    background-size: 100px 100px,100% 100%;
    background-repeat: no-repeat,repeat;
    animation: myfirst 5s 2s forwards;
    -moz-animation: myfirst 5s 2s forwards;
    -webkit-animation: myfirst 5s 2s forwards;
    -webkit-animation-delay: 4s;
    -moz-animation-delay: 4s;
}


@-moz-keyframes myfirst
{
0%   { -moz-opacity: 0.8; -moz-background-size: 100px 100px,100% 100%;}
25%  { -moz-background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); -moz-background-position: 20px 90px, 0px 0px; -moz-background-repeat: no-repeat,no-repeat; -moz-background-size:  100px 100px,100% 100%;}
50%  { -moz-background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); -moz-background-position: 40px 90px, 0px 0px; -moz-background-repeat: no-repeat,no-repeat; -moz-background-size:  100px 100px,100% 100%;}
100% { -moz-background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); -moz-background-position: 60px 90px, 0px 0px; -moz-background-repeat: no-repeat,no-repeat; -moz-background-size:  100px 100px,100% 100%;}
}

这段代码不适用于firefox这个只能运行的chrome。

background-image在Firefox中无法制作动画。检查规范HERE

Answer 2

摆脱-moz关键帧中的每个myfirst（但保留在-moz-keyframes）。

例如：

@-moz-keyframes myfirst
{
  0%   { opacity: 0.8; background-size: 100px 100px,100% 100%;}
  25%  { background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); background-position: 20px 90px, 0px 0px; background-repeat: no-repeat,no-repeat; background-size:  100px 100px,100% 100%;}
  50%  { background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); background-position: 40px 90px, 0px 0px; background-repeat: no-repeat,no-repeat; background-size:  100px 100px,100% 100%;}
  100% { background: url("animation/vahan1.png"), url("animation/background_girl.jpg"); background-position: 60px 90px, 0px 0px; background-repeat: no-repeat,no-repeat; background-size:  100px 100px,100% 100%;}
}

但是，background-image在Firefox中尚无动画效果。
