Changchun web design introduces two design patterns. In the past, general web pages usually used tables for layout design. The advantage of this method lies in its fast design and production speed, especially in visual web editors like Microsoft FrontPage, where such design appears intuitive and convenient. However, increasingly complex layouts require many nested table designs, making the web code lengthy and complicated, increasing file size, and making it difficult for search engines to find. Additionally, this approach is not conducive to the redesign of large websites. As the support for CSS in mainstream web browsers has improved, a new web design pattern has emerged in recent years. This revolution in the industry is known as "web reconstruction," with its core being the separation of web style and content (en: Separation of style and content). Markup languages (such as HTML, XML) are responsible for defining the content of the page but cannot define anything related to the website's appearance (style). The website's style is managed by separate CSS files. In terms of layout, the new pattern advocates using DIVs defined by CSS for page layout, restoring tables to their original function of arranging data. This pattern offers many benefits, such as assisting search engines in finding web pages, reducing file size and improving browsing speed. Moreover, since one CSS file can control multiple pages, this greatly facilitates the redesign process. Since W3C is a strong advocate of this mode, the compliance of web pages with W3C standards can be automatically tested on the W3C website. This mode also has drawbacks; one weakness is that the effects may vary across different browsers, mainly due to numerous defects in Microsoft Internet Explorer's support for CSS documents. On the other hand, when designing CSS, the goal is not clearly visible, making it seem less intuitive. A web page is actually a file stored on a computer somewhere in the world, and this computer must be connected to the internet. Web pages are identified and accessed via URLs. After entering a URL in the browser, after a complex yet rapid process, the webpage file is transmitted to your computer, then interpreted by the browser to display its content before your eyes.
