Detailed explanation of HTML5 browser compatibility solutions
Currently, most browsers support HTML5. However, some lower version browsers have some problems with HTML5 support.
Lower version browsers support HTML5
all browsers, and unrecognizable elements will be automatically processed as inline elements. Therefore, you can use the following method to teach the browser to handle "unknown" HTML elements.
Defining HTML5 elements as block elements
HTML5 defines 8 new HTML semantic elements. All these elements are block-level elements.
In order to allow older versions of browsers to display these elements correctly, you can set the display attribute of CSS to block:
header, section, footer, aside, nav, main, article, figure { display: block; }
:
<!DOCTYPE html><html><head><meta charset="utf-8">
<title>为 HTML 添加新元素</title>
<script>document.createElement("myElement")</script>
<style>
myElement{
display: block;
background-color: #ddd;
padding: 50px;
font-size: 30px;
}
</style>
</head>
<body>
<h1>我的第一个标题</h1>
<p>我的第一个段落。</p>
<myElement>我的第一个新元素</myElement>
</body>
</html>
We can use the "HTML5 Enabling
JavaScript", "shiv" created by Sjoerd Visscher to solve this problem:
<!--[if lt IE 9]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]-->
<!--[if lt IE 9]> <script src="http://apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js"></script> <![endif]-->
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>渲染 HTML5</title> <!--[if lt IE 9]> <script src="http://apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js"> </script> <![endif]--></head><body><h1>我的第一个HTML5页面</h1> <article>Hello,world!</article> </body> </html>

Modular design allows extended functions, such as support for SSL encryption and dynamic web pages; 3. Configuration files (such as virtual host configurations) need to be carefully set to avoid security vulnerabilities, and optimize performance parameters, such as thread count and timeout time, in order to build high-performance and secure web applications.

Nginx performance monitoring and troubleshooting are mainly carried out through the following steps: 1. Use nginx-V to view version information, and enable the stub_status module to monitor the number of active connections, requests and cache hit rate; 2. Use top command to monitor system resource occupation, iostat and vmstat monitor disk I/O and memory usage respectively; 3. Use tcpdump to capture packets to analyze network traffic and troubleshoot network connection problems; 4. Properly configure the number of worker processes to avoid insufficient concurrent processing capabilities or excessive process context switching overhead; 5. Correctly configure Nginx cache to avoid improper cache size settings; 6. By analyzing Nginx logs, such as using awk and grep commands or ELK

The Installation, Configuration and Optimization Guide for HDFS File System under CentOS System This article will guide you how to install, configure and optimize Hadoop Distributed File System (HDFS) on CentOS System.

Use tools such as awk to parse logs and count indicators such as visits, error rates, etc.; 3. Write more complex scripts according to needs or use more advanced tools, such as goaccess, to analyze data from different dimensions; 4. For massive logs, consider using distributed frameworks such as Hadoop or Spark. By analyzing logs, you can identify website access patterns, improve content strategies, and ultimately optimize website performance and user experience.

There are many ways to monitor the status of HDFS (Hadoop Distributed File System) on CentOS systems. This article will introduce several commonly used methods to help you choose the most suitable solution. 1. Use Hadoop’s own WebUI, Hadoop’s own Web interface to provide cluster status monitoring function. Steps: Make sure the Hadoop cluster is up and running. Access the WebUI: Enter http://:50070 (Hadoop2.x) or http://:9870 (Hadoop3.x) in your browser. The default username and password are usually hdfs/hdfs. 2. Command line tool monitoring Hadoop provides a series of command line tools to facilitate monitoring
