The editor of Downcodes brings you a detailed explanation of the `cellpadding` and `cellspacing` attributes in HTML and how browsers work. This article will explain the difference between these two properties in simple terms and combine it with the browser request process to help you better understand how web pages are constructed and displayed. Through the analysis of HTML table attributes and network request process, I hope it can help you improve your web design and front-end development skills.
The main difference between cellpadding and cellspacing is that cellpadding is used to fix the width between the edge of a cell and its content, i.e. it creates white space within the cell between the text and the cell border. However, cellspacing can be used to manage the space between individual cells in a table.

However, cellspacing can be used to manage the space between individual cells in a table.
The property that sets the space of a cell between its content and outer border is called cellpadding. In other words, the distance between the cell's surrounding content and the cell's borders is managed through the cellpadding property. The units for this distance can be implicit in HTML as pixels or percentages.
According to the user's needs, the cellpadding attribute value can also be 0. It is used to separate text from each other, thus improving the appearance.
The Cellspacing property controls the distance between individual cells in the table. By using this property, designers can easily change the space between the edges of different adjacent cells.
The Cellspacing property is mainly used in web design. Different languages have completely different syntax for cellspacing, for example using the "border-spacing" attribute in CSS and "cellspacing" in HTML.

1. When we enter a string of URLs in the browser, and the URL is displayed in the browser, when the browser receives the instruction, it will open a separate thread to process it. First, it determines whether the address entered by the user is a reasonable address. Is it an HTTP request? Then analyze the URL. If it is cached, the local file will be called and 200 will be returned. If there is no request, the browser will initiate a request.
2. Obtain the IP address through domain name resolution. The information in the browser will be requested by IP. The browser client sends a message to the server and performs data transmission and communication.
3. Then enter the backend of the website. The server has a lot of code. The server will process and respond according to the execution backend of the URL. If the page has been visited and compared with the server file, 304 will be returned consistently.
4. The browser receives the returned information and starts to download the HTML file, render it and build the DOM tree, and use the specified js script to render and rearrange the css style, and then the page will be displayed in the browser.
I hope the explanation by the editor of Downcodes can help you understand the `cellpadding`, `cellspacing` properties and the working mechanism of the browser. If you have any questions, please feel free to ask!
