1. CSS controls the size of the img image
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="http://www.softwhy.com/" />
<style type="text/css">
img{
width:120px;
height:100px;
}
</style>
</head>
<body>
<img src="mytest/div+css/border.jpg"/>
</body>
</html>The above code sets the length of the img image The widths are 120px and 100px respectively.
However, it should be noted that using css to roughly set the image size may cause deformation.
If you don’t want the image to be deformed, pay attention to the aspect ratio of the image.
2. Add a border to the img image
In actual application, a border effect may be added to the image.
This can be achieved using the border attribute of CSS.
The code example is as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="http://www.softwhy.com/" />
<style type="text/css">
img{
width:220px;
height:100px;
border:2px solid blue;
}
</style>
</head>
<body>
<img src="mytest/div+css/border.jpg"/>
</body>
</html>The above code adds a blue border with a width of 2px to the img image.
For more information about borders, please refer to the CSS border chapter.

The picture is used as a link, that is, it is placed within 3499910bf9dac5ae3c52d5ede7383485.

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="http://www.softwhy.com/" />
<style type="text/css">
img{
width:40px;
height:20px;
border:2px solid blue;
border:none;
}
</style>
</head>
<body>
<a href="#"><img src="mytest/div+css/border.jpg"/></a>>
</body>
</html>The above code puts the image into the link 3499910bf9dac5ae3c52d5ede7383485, and click to achieve the jump action.
It is important to note that when you put the image into the link, the image may have unnecessary borders. Just add border:none.

<style type="text/css">
div{
width:300px;
height:300px;
text-align:center;
background-color:#ccc;
}
img{
width:100px;

}
</style>

<style type="text/css">
div img{

}
</style>
</head>
<body>
<div><input type="text"/><img src="mytest/demo/1.jpg"></div>
</body>
</html>The above code can achieve the vertical alignment effect of the text box and the verification code.
