[英]Making a div appear upon hovering on another div
I have searched a lot for this, I can not find an answer. 我为此进行了很多搜索,找不到答案。 I want the div SubTopicInfo1 to appear when hovering over the div subTopicNav1. 我希望将div SubTopicInfo1悬停在div subTopicNav1上时出现。 I need it to be only CSS. 我只需要CSS。

Thanks. 谢谢。
You wont be able to do so with just CSS in your situation. 在您所处的环境中,仅使用CSS就无法做到这一点。
#subTopicNav1:hover + #SubTopicInfo1 {}
Works if #SubTopicInfi1 is next to (after #subTopicInfo1 closing tag) the container. 如果#SubTopicInfi1在容器旁边(在#subTopicInfo1关闭标记之后),则可以使用。
explained here: 在这里解释:
How to affect other elements when a div is hovered 当div悬停时如何影响其他元素
So you probably should look into a solution with Jquery/javascript! 因此,您可能应该考虑使用Jquery / javascript解决方案!
Please try something like this: 请尝试这样的事情:
(Hide the extra info panel by default, then make it visible on :hover like below) (默认情况下,隐藏额外的信息面板,然后使其在:hover上可见,如下所示)
<style>
.link {
display: block;
}
.link:hover p{
visibility: visible;
}
.info{
visibility: hidden;
}
</style>
<body>
<div class="link">
<a href="#"> Text Here </a>
<p class="info"> Info Here</p>
</div>
</body>
Here is the working Demo http://jsfiddle.net/H9fGP/1/ maybe its not the exact example. 这是可以正常工作的演示http://jsfiddle.net/H9fGP/1/ 。 but I hope it helps :) 但我希望它会有所帮助:)
the main thing is that the sub info has absolute position 最主要的是,子信息具有绝对位置
I rearanged the html and added some css. 我重新整理了html并添加了一些CSS。
.container
{
border-top: 5px solid #FFD640;
margin-top: 25px;
}
#SubTopicNav
{
position:relative;
}
#SubTopicNav > div > div
{
position:absolute;
left:200px;
top:0px;
display:none;
width: 600px;
height: 400px;
margin-top: 25px;
float: left;
}
#SubTopicInfo
{
display:none;
background-color: #FFD640;
}
#SubTopicNav > div:hover >div
{
display: block;
}
