我是网站设计新手，Javascript，CSS3＆amp; JQuery的 我成功设法在将鼠标移动到相应区域时自动隐藏页面页眉/页脚，但现在我想在用户在页面的任何区域移动鼠标时显示页面页脚/页眉。我可以只使用CSS3，还是应该使用JQuery或Javascript？如果它不能仅使用CSS3完成，您能否帮助我使用JQuery或JavaScript如何做到这一点。
这是我的CSS3文件：

这是我的HTML文件：

<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" charset="utf-8" />
<link rel="stylesheet" type="text/css" href="styling.css">

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.1.js"></script>
<!-- following part for smooth scrolling -->
<script>
$(document).ready(function(){
$("button").click(function(){
console.log("Inside mousemove event handler");
$("#header").animate({opacity:1},500).delay(1000).animate({opacity:0},500);
$('#footer').animate({opacity:1},500).delay(1000).animate({opacity:0},500);
});
});
</script>
</head>
<body>
<div id="header">
</div> <!-- ending of header_contents tag -->
<!-- <div class="clear"></div> -->
<div>
<h1 id="alliance" style="margin-top:100px">Main</h1>
<button>Click to fade boxes</button>
</div>
<div>
<footer id="footer">
</footer>
</div>
</body>
</html>
现在，而不是使用按钮淡入标题和＆amp;页脚1秒然后淡出它们，我想用任何页面部分上的用户鼠标移动来替换按钮。

简单：
<style>
#header{
transition: 1s;
background-color: black;
}
.mouse_come_here{
width: 100%;
height: 20%;
opacity: .0;
}
.visible{
height: 100%;
opacity: 1.0;
}
</style>
<script>
$(document).ready(function(){
//When Mouse Is On Them
$("#header").mouseover(function(){
$(this).addClass("visible");
$(this).addClass("come_here_mouse");
});
//When Mouse Leaves Them
$("#header").mouseout(function(){
$(this).removeClass("visible");
$(this).addClass("come_here_mouse");
});
});
</script>

您可以使用CSS状态选择器简单地执行此操作，如下所示：
footer{
background-color: #60424ca9;
opacity: 0;
position: fixed;
bottom: 0;
width: 100vw;
}
footer:hover{
opacity: 1;
}
