以下可能是一种选择。
对于 HTML:
<div style="list-style-type:none;width:400px" class="box">
    <ul id="lastfm">
        <li>...</li>
        ...
        <li class="overlay"></li>
    </ul>
</div>
添加一个额外的项目li.overlay并使用 CSS 将背景图像附加到它:    
.box ul#lastfm {
    padding-right: 75px;
    position: relative; /* So that the absolute positioning based on this block... */
    margin-left: 0;
    list-style: square outside none;
}
.overlay {
    outline: 1px dashed blue; /* for demo only */
    position: absolute;
    z-index: 1; /* to make sure it is in front of list items... */
    bottom: 0;
    right: 0;
    height: 70px; /* will depend on your images... */
    width: 110px;
    background-attachment: scroll, scroll;
    background-clip: border-box, border-box;
    background-color: transparent;
    background-image: ...
    background-origin: padding-box, padding-box;
    background-position: right bottom, right bottom, left 0px;
    /* Make sure syntax is correct, otherwise Safari gets confused... */
    background-repeat: no-repeat, no-repeat;
    background-size: auto auto, 70px auto, auto auto;
}
确保 for 的语法background-position绝对正确,否则 Safari 将无法识别。Firefox 更宽容一些。
