css中有两种方式可以将块元素显示与隐藏
一、visibility属性
1.visibility:hidden 元素被隐藏,位置被保留,影响布局
<!DOCTYPE html>
<html lang="en">
<head>
<title>Document</title>
<style>
.box1{
border: 1px solid red;
width: 100px;
}
h1 {
visibility: hidden;
/* 控制单词换行 */
word-break: break-all;
}
</style>
</head>
<body>
<div class="box1">
<h1>通过visibility隐藏</h1>
</div>
</body>
</html>
如图所示：
2. visibility:visible 元素可见的
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.box1{
border: 1px solid red;
width: 100px;
}
h1 {
visibility: visible;
/* 控制单词换行 */
word-break: break-all;
}
</style>
</head>
<body>
<div class="box1">
<!-- <img src="img/1.jpg" alt=" " width="100px"> -->
<h1>通过visibility隐藏</h1>
</div>

二、display属性
1.display:none 元素被隐藏,不影响布局
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

<style>
.box1{
border: 1px solid red;
width: 100px;
}

display: none;
/* 控制单词换行 */
word-break: break-all;
}
</style>
</head>
<body>
<div class="box1">
