Web standards are a set of specifications and guidelines designed to ensure the consistency and accessibility of web pages across different browsers and devices. It includes specifications for technologies such as HTML, CSS, and JavaScript, as well as best practices for web page structure, style, and interaction. However, Web standards do not cover all aspects and technologies, and some content that Web standards do not include will be introduced below.
1. Back-end development technology: Web standards mainly focus on front-end development, that is, the structure, style and interaction of web pages. It does not involve back-end development technologies, such as server-side programming languages (such as PHP, Python, Java, etc.) and database management systems (such as MySQL, Oracle, etc.).
2. Graphic design and visual effects: Web standards emphasize the structure and content of web pages rather than graphic design and visual effects. Although CSS can be used to control the style of web pages, it does not provide complex graphic design functions, such as image processing, vector graphics, and animation effects.
3. Multimedia technology: Web standards do not involve all multimedia technologies, such as audio, video, and real-time communication. Although HTML5 introduces some multimedia elements and APIs, it does not include all multimedia features and technologies.
4. Mobile application development: Web standards mainly focus on the consistency and accessibility of web pages on different browsers and devices, rather than the development of mobile applications. Mobile applications usually use specialized development frameworks and technologies, such as React Native and Flutter.
5. Security and privacy protection: Web standards do not cover all security and privacy protection technologies. While it provides some basic security measures, such as protection against cross-site scripting attacks (XSS) and cross-site request forgery (CSRF), it does not include all security and privacy protection features.
Although web standards do not include the above content, they are still the foundation and important guiding principles of web development. Following web standards can improve the accessibility, usability, and maintainability of web pages, while also helping to improve web page rankings in search engines and user experience. Therefore, developers should be familiar with and follow web standards, as well as understand other related technologies and best practices to meet different development needs and user expectations.
