What is the usage of clear in css
The function of clear in css is to clear the floating effect of elements.
The clear attribute specifies that floating elements are not allowed on the left or right side of the paragraph.
In CSS1 and CSS2, this is achieved by automatically adding a top margin to clear elements (i.e. elements with the clear attribute set). In CSS2.1, clear space is added above the element's upper margin, but the margin itself does not change.
No matter what kind of change, the final result is the same. If it is declared to be cleared on the left or right, the top outer border of the element will be just below the bottom margin of the floating element on that side.
clear attribute value:
eft No floating elements are allowed on the left.
#right Floating elements are not allowed on the right side.
Both Floating elements are not allowed on the left and right sides.
none Default value. Allows floated elements to appear on both sides.
inherit specifies that the value of the clear attribute should be inherited from the parent element.
The example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<style>
img
{
float:left;
}
p.clear
{
clear:both;
}
</style>
</head>
<body>
<img src="/static/imghw/default1.png" data-src="logocss.gif" class="lazy" style="max-width:90%" style="max-width:90%" / alt="What is the usage of clear in css" >
