Delving deeper into the scope of web standards languages, what languages ​​are covered?

Web standards refer to a series of specifications that each web page on the Internet needs to follow to ensure that web pages can display and run correctly on different browsers and devices. These standards include languages ​​such as HTML, CSS and JavaScript. This article will provide an in-depth analysis of the language range covered by web standards.

First of all, HTML (HyperText Markup Language) is the basic language for building web pages. It uses markup to define the structure and content of the page, including titles, paragraphs, images, links, etc. The latest version of the HTML standard is HTML5, which introduces many new features and elements, such as video players, local storage, form validation, etc., to improve user experience and developer capabilities.

Closely related to HTML is CSS (Cascading Style Sheets), which is used to control the style and layout of the page. CSS allows developers to use selectors and attributes to style page elements, including text color, font, border, background, layout, etc. The latest version of CSS is CSS3, which provides more styling options and effects such as shadows, gradients, animations, etc., making the appearance of the page richer and more attractive.

In addition to HTML and CSS, web pages usually use JavaScript to achieve interactive and dynamic effects. JavaScript is a scripting language that can implement complex functions in web pages, such as form validation, image carousel, data interaction, etc. It can interact with HTML and CSS to achieve dynamic updates of page elements and user interaction with the page. JavaScript is also developing very rapidly. There are now many frameworks and libraries that can help developers write JS code more efficiently, such as jQuery, React, Angular, etc.

In addition to HTML, CSS and JavaScript, web standards also cover a number of other languages ​​and technologies. XML (eXtensible Markup Language) is an extensible markup language used to transmit and store data. It is usually used for the exchange and description of data, such as RSS subscriptions, configuration files, etc.

In addition, Web standards also involve server-side languages ​​and technologies. Server-side scripting languages ​​such as PHP, Python, and Ruby are widely used in web development to handle user requests, dynamically generate page content, interact with databases, etc. At the same time, SQL (Structured Query Language) is a language used for database management, used to create, query and modify data in the database.

In addition, Web standards also cover some security-related languages ​​and technologies, such as HTTPS, SSL/TLS, OAuth, etc. These technologies ensure users' security and privacy protection when browsing the web.

In short, web standards cover a wide range of languages, including HTML, CSS, JavaScript, XML, PHP, Python, Ruby, SQL, etc. Together, these languages ​​and technologies form the foundation of the modern web, allowing us to create rich, interactive web applications. In the ever-evolving Internet era, it is very important for web developers to understand and master these languages ​​and technologies.
