jquery.scrollbar.js滚动条示范脚本

admin

假定我们要求.body里的.pb元素自动产生纵向滚动条。

首先须引用jquery.min.js,jquery.scrollbar.min.js，systhemes/js中自带。
CSS：
.body .pb{ width: 500px; height: calc(100% - 100px); margin-left:auto; margin-right:200px; background:rgba(51, 146, 202, 0.9); color:#fff; padding:50px 20px; box-shadow:0 0 10px #333;}
.scroll-wrapper {
    position: relative;
}
.scroll-wrapper > .scroll-content {
    border: none !important;
    height: auto;
    left: 0;
    margin: 0;
    max-height: none;
    max-width: none !important;
    overflow: hidden !important;
    padding: 0;
    position: relative !important;
    top: 0;
    box-shadow: none;
    background: none;
}
.scroll-wrapper > .scroll-content::-webkit-scrollbar {
    height: 0;
    width: 0;
}
.scroll-element {
    display: none;
}
.scroll-element, .scroll-element div {
    box-sizing: content-box;
}
.scroll-element.scroll-x.scroll-scrollx_visible,
.scroll-element.scroll-y.scroll-scrolly_visible {
    display: block;
}
.scroll-element .scroll-bar,
.scroll-element .scroll-arrow {
    cursor: default;
}
.scroll-textarea {
    border: 1px solid #cccccc;
    border-top-color: #999999;
}
.scroll-textarea > .scroll-content {
    overflow: hidden !important;
}
.scroll-textarea > .scroll-content > textarea {
    border: none !important;
    box-sizing: border-box;
    height: 100% !important;
    margin: 0;
    max-height: none !important;
    max-width: none !important;
    overflow: scroll !important;
    outline: none;
    padding: 2px;
    position: relative !important;
    top: 0;
    width: 100% !important;
}
.scroll-textarea > .scroll-content > textarea::-webkit-scrollbar {
    height: 0;
    width: 0;
}
.body .pb > .scroll-element,

.body .pb > .scroll-element .scroll-element_track { display: none; }
.body .pb > .scroll-element .scroll-bar {
