获取顶部的 div 及其内容：悬停而不干扰其他内容

Question

我创建了一个包含多个框的弹出窗口。我想要做的是当用户将鼠标悬停在任何“.deviceboxes”上时，特定的盒子宽度应该扩大并且它应该在网页上的每个内容上都可见。为了实现这一点，我编写了“.deviceboxes:hover”，仅适用于行中的第一个框。但是当我将鼠标悬停在其他盒子上时，它会扰乱布局。我应该怎么做才能做到这一点？

以下是我的 HTML 内容

<div class="modal-body">
    <div id="leftsection">
      <div class="deviceboxes">
            <div id="boxlabel_NetworkDevice_97" class="title">NetworkDevice_97</div>
                <div id="NetworkDevice_97_1" class="cmds">Command 1</div>
                <div id="NetworkDevice_97_0" class="cmds">Command 2</div>
            </div>

      <div class="deviceboxes mrgnleft">
        <div id="boxlabel_NetworkDevice_9" class="title">NetworkDevice_9</div>
        <div id="NetworkDevice_9_1" class="cmds"Command_1</div>
        <div id="NetworkDevice_9_0" class="cmds">Command_2</div>
      </div>
    </div>
</div>

以下是一个 CSS ：

.modal-body{ overflow: hidden; position: relative;} 
#fetch_commands{ left: 34% !important; width:1000px !important; height:500px; overflow: hidden;}
#leftsection{ float: left; width: 730px; height: 400px; overflow-y: scroll; overflow-x: hidden; min-height: 200px;}
#rightsection{position: relative; width: 200px; height: 400px; overflow-y: scroll; overflow-x: hidden; margin-left: 10px; padding-left: 20px; }
.netDevices { width:98%; padding: 5px 0px 5px 5px; cursor: pointer;}
.netDevices:hover {background: #406BA3; color: #FFF !important; -webkit-transition: all 1s; -moz-transition: all 1s; -o-transition: all 1s;}
.processing{ background: #006002; color: #FFF;}
.success{ background: none; color: #006002;}
.failed{ background: node; color: #FF0A16;}

.deviceboxes{ float: left; width: 215px; height: 200px; border: 1px solid #666; overflow-x: hidden;-webkit-transition: all 1s; -moz-transition: all 1s; -o-transition: all 1s;}
.deviceboxes:hover{ position:absolute !important; z-index:999999; width:500px !important; -webkit-transition: all 1s; -moz-transition: all 1s; -o-transition: all 1s;}
.title{ width: 100%; text-align: center; background: #000; color:#FFF; padding:10px; cursor: pointer;}
.cmds{ width: 195px; text-align: left; background: none; color:#000; padding:2px; margin-left: 5px; cursor: pointer; overflow-x: hidden; white-space: nowrap;}
.mrgnleft{ margin-left:10px; }
.mrgntop{ margin-top:10px; }
.navbar-inner { min-height: 65px!important; }

Answer 1

您可以进行 2 项简单的更改。

1. 为了补偿从 215 - 500px 增加的宽度，您可以设置负边距，以便将以下元素拉回其原始位置。在这种情况下，它需要是 215-500 = -285px。

2. 下一步，而不是使用position:absolute。您可以将position:relative 用于所有.deviceboxes（不仅仅是悬停），因此它仍然会对页面流产生一些影响。这也意味着 z-indexing 将按照您的意愿工作。

请注意，您只需将transition 设置应用于基本状态，而不是hover，如果它们相同的话。只是节省了几位。
