How to use CSS3 to achieve the magnification effect of images
Method 1, use the transform attribute with the scale() method
The transform attribute applies 2D to the element or 3D conversion. This property allows us to rotate, scale, move or tilt the element.
scale(x,y) defines 2D scaling transformation.
The example is as follows:
<!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>
*{
margin:0 auto;
}
.img1{
background:pink;
transform:scale(1.5,1.5);
}
</style>
</head>
<body>
<img class="img1 lazy" src="/static/imghwm/default1.png" data-src="1115.08.png" alt="How to use CSS3 to enlarge images" >
<br><br>
<img class="img2 lazy" src="/static/imghwm/default1.png" data-src="1115.08.png" alt="How to use CSS3 to enlarge images" >
</body>
</html>Output result:
##Method 2, using the width and height attributes
The two properties are used to set the width and height of the element respectively. The example is as follows<!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>
*{
margin:0 auto;
}
.img1{
width:300px;
height:200px;
}
</style>
</head>
