Question

我有一个隐藏/显示悬停的div。位置设置是绝对的，因此div的背景变得透明。如果position设置为relative，则在悬停时会影响父div高度。那么如何阻止背景以便内容不可见。

需要css的解决方案。给出的样本 - ＆gt;

$(document).ready(
    function() {
        $("#hover").hover(function() {
            $("#message").toggle();
        });
    });

#message {
    border: 1px solid;
    padding: 10px;
    box-shadow: 5px 10px #888888;
    position:absolute;
    display:none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#"id="hover" >Click Here</a>
<div id="message">
  <b>Hidden Content</b>
  <br/>This is a very large content which overlaps the content at background.<br/><br/>So the content in background should not be seen.
</div>
<div>This is another text whose content should be hidden under the popup.</div><br/>
<div>One more text added whose content is visible even if the hidden content is visible.</div>

我已经通过添加Z-index和background-color更新了代码。希望这是你正在寻找的。

$(document).ready(
    function() {
        $("#hover").hover(function() {
            $("#message").toggle();
        });
    });

#message {
    border: 1px solid;
    padding: 10px;
    box-shadow: 5px 10px #888888;
    position:absolute;
    display:none;
z-index:9;
background:#fff
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#"id="hover" >Click Here</a>
<div id="message">
  <b>Hidden Content</b>
  <br/>This is a very large content which overlaps the content at background.<br/><br/>So the content in background should not be seen.
</div>
<div class="setPosition">This is another text whose content should be hidden under the popup.</div><br/>
<div>One more text added whose content is visible even if the hidden content is visible.</div>

你需要一个白色背景。

您也可以相应地更改宽度

编辑：你已经在使用jQuery = /

了

$(document).ready(
  function() {
    $("#hover").hover(function() {
      $("#message").toggle();
    });
  });

#message {
  border: 1px solid;
  padding: 10px;
  box-shadow: 5px 10px #888888;
  position: absolute;
  display: none;
  background: #FFF;
  width: 90%;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" id="hover">Click Here</a>
<div id="message">
  <b>Hidden Content</b>
  <br/>This is a very large content which overlaps the content at background.<br/><br/>So the content in background should not be seen.
</div>
<div>This is another text whose content should be hidden under the popup.</div><br/>
<div>One more text added whose content is visible even if the hidden content is visible.</div>
