使用 CSS3 Animation 复现

直接扒 JS 代码固然省时省力……【省嘛？好像没有吧，当初扒的时候眼睛都快瞎了】,但是 JS 似乎不是每次都起作用……

然后我就自己用 CSS3 Animation 重写这个动画。CSS 如下：

#banner_wave_1 {
    width: auto;
    height: 65px;
    background: url(https://oss.amogu.cn/blog/sakura/images/wave_1.png) repeat-x;
    _filter: alpha(opacity=80);
    position: absolute;
    bottom: 0;
    width: 400%;
    left: -236px;
    z-index: 5;
    opacity: 1;
    transiton-property: opacity, bottom;
    transition-duration: .4s, .4s;
    animation-name: move2;
    animation-duration: 240s;
    animation-fill-mode: backwards;
    animation-timing-function: linear;
    animation-iteration-count: infinite;
}
 
#banner_wave_2 {
    width: auto;
    height: 80px;
    background: url(https://oss.amogu.cn/blog/sakura/images/wave_2.png) repeat-x;
    _filter: alpha(opacity=80);
    position: absolute;
    bottom: 0;
    width: 400%;
    left: 0;
    z-index: 4;
    opacity: 1;
    transiton-property: opacity, bottom;
    transition-duration: .4s, .4s;
    animation-name: move2;
    animation-duration: 160s;
    animation-fill-mode: backwards;
    animation-timing-function: linear;
    animation-iteration-count: infinite;
}
 
/* move1和move2只是方向不同，根据喜好自选即可。 */
/* 没做浏览器适配，具体哪些浏览器会生效未知，反正Chrome没什么问题。*/
 
@keyframes move1 {
    100% {
        background-position: 100% 0;
    }
}
 
@keyframes move2 {
    100% {
        background-position: -100% 0;
    }
}

两个DIV的穿插位置

在路径 /wp-content/themes/Sakura/layouts 下，打开 imgbox.php。在下面所述位置插入。

    <div class="focusinfo">
        <?php if (akina_option('focus_logo')):?>
……
