1. Four implementations of css hidden elements
1. visibility: hidden, set the element to be hidden
Code example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>元素隐藏--visibility: hidden</title>
<style>
.demo{
width: 800px;
height: 200px;
margin: 50px auto;
}
span{
visibility: hidden;
}
</style>
</head>
<body>
<div class="demo">
<p>元素隐藏1--visibility: hidden,元素隐藏2--visibility: hidden,元素隐藏3--visibility: hidden</p>
<p>元素隐藏1--visibility: hidden,<span>元素隐藏2--visibility: hidden</span>,元素隐藏3--visibility: hidden</p>
</div>
</body>
</html>Rendering:
The visibility attribute specifies whether the element is visible. Setting its value to hidden only visually hides the element. The hidden element itself still occupies its own position and contributes to our web page layout.
2. Opacity: 0, set the element to hide
Code example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>元素隐藏--opacity: 0</title>
<style>
.demo{
width: 800px;
height: 200px;
margin: 50px auto;
}
span{
opacity: 0;
}
</style>
</head>
<body>
<div class="demo">
<p>元素隐藏1--opacity: 0,元素隐藏2--opacity: 0,元素隐藏3--opacity: 0</p>
<p>元素隐藏1--opacity: 0,<span>元素隐藏2--opacity: 0</span>,元素隐藏3--opacity: 0</p>
</div>
</body>
</html>Rendering:
opacity The property means to set the transparency of an element. It is not designed to change the bounding box of an element. This means that setting opacity to 0 only visually hides the element. The element itself still occupies its own position and contributes to the layout of the web page. This is similar to visibility: hidden above.
3. display:none, set the element to hide
Code example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>元素隐藏--display:none</title>
<style>
.demo{
width: 800px;
height: 200px;
margin: 50px auto;
}
span{
opacity: 0;
}
</style>
</head>
<body>
<div class="demo">
<p>元素隐藏--display:none,元素隐藏--display:none,元素隐藏--display:none</p>
<p>元素隐藏--display:none,<span>元素隐藏--display:none</span>,元素隐藏--display:none</p>
</div>
</body>
</html>Rendering:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>元素隐藏--position: absolute</title>
<style>
.demo{
width: 800px;
height: 200px;
margin: 50px auto;
}
span{
position: absolute;
top: -9999px;
left: -9999px;
}
</style>
</head>
<body>
<div class="demo">
<p>元素隐藏1--position: absolute,元素隐藏2--position: absolute,元素隐藏3--position: absolute</p>
<p>元素隐藏1--position: absolute,<span>元素隐藏2--position: absolute</span>,元素隐藏3--position: absolute</p>
</div>
</body>
</html>Rendering:
##position : absolute, the main principle of setting the hidden element is to make it invisible on the screen by setting the top and left of the element to a large enough negative number.
2. Difference
1.visibility:hidden The element will be hidden, but it will not disappear and still occupy space. The original HTML style will not be changed after hiding; It will be inherited by descendants, who can also unhide it by setting visibility: visible;
Events that have been bound to this element will not be triggered. Dynamically modifying this property will cause redrawing.
2. Opacity:0
Only the transparency is 100%, the element is hidden, and it still occupies space. The original html style will not be changed after hiding;
will be inherited by child elements, and the child Elements cannot be unhidden through opacity=1;
3. display:none
does not occupy space and hides the element, so dynamically changing this attribute will cause rearrangement (change the page layout), which can be understood as placing the element on the page. The same thing happens when the element is deleted;
will not be inherited by descendants, but its descendants will not be displayed. After all, they are all hidden together.
4. position: absolute
position: absolute, by setting the top and left of the element to a large enough negative number, it will be invisible on the screen and have a dynamic interactive effect. .
