Question

有一些浮动div在彼此顶部。当用户在它们上面盘旋时，高度随着jQuery命令而增加：

 $(".concert").hover(function () {
        $(this).parent().find(".concert[opened='opened'] .concertbody").animate({ height: "0px" }, { duration: 400, queue: false });
        $(this).parent().find(".concert[opened='opened'] .concertHeader .middle").css("background-image", "url(Images/concert-header-back.png)");
        $(this).parent().find(".concert[opened='opened'] .concertbody").css("border", "none");
        $(this).parent().find(".concert[opened='opened'] .concertbody .concertDetails").css("visibility", "hidden");

        $(this).find(".concertbody").animate({ height: "276px" }, { duration: 400, queue: false });
        $(this).find(".concertHeader .middle").css("background-image", "url(Images/concert-header-back-hover.png)");
        $(this).find(".concertbody").css("border", "1px solid whitesmoke");
        $(this).find(".concertbody .concertDetails").css("visibility", "visible");
        $(this).parent().find(".concert[opened='opened']").removeAttr("opened");
        $(this).attr("opened", "opened");
    });

布局正常，其他div下降，但是当我使用firebug并检查其他div标签时，位置不会改变。

页面的Html：

 <div class="parent">
                <div class="concert" id="ct1">
                    <div class="concertHeader">

我该怎么做才能解决这个问题？

此致

Answer 1

.parent .concert { width: 324px; margin: 2px; }

.parent .concert

上有一个固定的高度

如果需要，您可以添加最小高度。

更改顶部div高度但低于项目不会改变位置
