Right now it only support 8 elements’ animation, due to minify the CSS file size, I don’t include more element’s animation in the CSS, you can add it by yourself in the jquery.onebyone.css:

/*support the 9th element*/
.animate8{
    -webkit-animation-duration: .6s;
    -webkit-animation-delay: 1.6s;
    -webkit-animation-timing-function: ease;
    -webkit-animation-fill-mode: both;
    -moz-animation-duration: .6s;
    -moz-animation-delay: 1.6s;
    -moz-animation-timing-function: ease;
    -moz-animation-fill-mode: both;
    -ms-animation-duration: .6s;
    -ms-animation-delay: 1.6s;
    -ms-animation-timing-function: ease;
    -ms-animation-fill-mode: both;
    animation-duration: .6s;
    animation-delay: 1.6s;
    animation-timing-function: ease;
    animation-fill-mode: both;              
}   

/*support the 10th element*/
.animate9{
    -webkit-animation-duration: .6s;
    -webkit-animation-delay: 1.8s;
    -webkit-animation-timing-function: ease;
    -webkit-animation-fill-mode: both;
    -moz-animation-duration: .6s;
    -moz-animation-delay: 1.8s;
    -moz-animation-timing-function: ease;
    -moz-animation-fill-mode: both;
    -ms-animation-duration: .6s;
    -ms-animation-delay: 1.8s;
    -ms-animation-timing-function: ease;
    -ms-animation-fill-mode: both;
    animation-duration: .6s;
    animation-delay: 1.8s;
    animation-timing-function: ease;
    animation-fill-mode: both;              
}
