鼠标移入和鼠标移出的提示,和样式的转换

鼠标移入和鼠标移出的提示:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        #DIV{
            width: 100px;
            height: 70px;
            border: 1px solid #aaaa22;
            display: none;
        }
    </style>
</head>
<body>
<lable onmouseover="document.getElementById('DIV').style.display='block';"
       onmouseout="document.getElementById('DIV').style.display='none';">
<input type="checkbox" >自动登录</lable>
<div id="DIV">选择需要谨慎</div>
</body>
</html>

注:lable标签的主要作用就是用来做一个框,鼠标进入这个框,就会显示提示内容,如果没有lable标签,只有当鼠标在按钮上时才显示提示内容。

        div{

        }
        .box1{
            width: 200px;
            height: 100px;
            border: 1px solid red;
