需要清除动物或所有潜水中的漂浮物

#animals {
    width: 100%;
    margin-left: 5px;
    margin-right: 5px;
    margin-bottom: 5px;
    text-align: center;
    position: relative;
    display: block;
    height: auto;
    overflow: hidden;       /* Added this.. */
}

因为您的图片采用浮动样式，所以在没有clearfix的自动高度中不会考虑它们的高度。

div:after //OR
#animals:after {
    display: table;
    content: '';
    clear: both;  
}
