Problem Description:

I recently taught a class for students, a web design class, and wrote a very, very simple landing page, but found that there would be a problem with the page style, and a blank line would appear at the bottom of the web page. At first I thought it was a problem with the 360 browser, but after checking it, it turned out that it was the ICBC online banking plug-in. The code and running effect diagram are as follows:

<!DOCTYPE html>
<html>
<head>
	<title>管理员入口</title>
    <style type="text/css">
    	 body{
    		border: 5px solid red;
			background-image: url("${webapp}/image/sysadmin/sysadmin-login-bg.png");
			background-repeat: no-repeat;
			background-size: cover;
    	}
    	
    	div{
    		border: 5px solid yellow;
    		color: white;
			font-family: "宋体";
    	}
    	
		input[type='text'],[type='password']{
			width: 20em;
			height: 2em;
		}
    </style>
</head>
<body>

	<div align="center">
	
		<h1>请先登录.</h1>
		<form action="${webapp}/sysadmin_login" method="post">
			<input type="text" name="account" placeholder="请输入账户" autocomplete="off" required="required" /><br/>
			<input type="password" name="password" placeholder="请输入密码" required="required" /><br/>
			<br/>
			<br/>
			<input type="submit" value="登陆"/>
		</form>
		
	</div>
	
</body>
</html>

Solution:

After the problem occurs, I have been confused, where is the problem? Then I checked it casually and found that this was caused by the ICBCChromeExtension plug-in of ICBC . Disable the plug-in and the problem is solved.

postscript:

This plug-in should be installed on the online banking assistant of ICBC. Because it must be installed if you want to use ICBC's online banking. But it’s okay to install this plug-in, the key is that you directly insert the code in each page, and it’s fine to insert the code, but the key is that the code you insert directly affects the display of my page!

I just want to say that the level of ICBC's software development team is really shitty . They are just a bunch of idiots and rice bags . They are in the ICBC system, and they can get their wages anyway, so they just eat and wait for death. This shows that their development level is really bad. Rooted, contempt ah, ha ha!
