What is the difference between w3c standards and web standards?

What is the difference between W3C standards and Web standards? Specific code examples are needed

In Web development, we often hear arguments about W3C standards and Web standards. Although they sound similar, they are actually two different concepts that refer to different concepts and specifications. This article will explain the differences between W3C standards and Web standards in detail, and provide some specific code examples to aid understanding.

W3C (World Wide Web Consortium) is a non-profit organization that develops and promotes standards for Web technology. W3C standards refer to a series of specifications and technical standards developed and recommended by W3C, covering all aspects of Web development, including HTML, CSS, JavaScript, XML, etc. These standards are developed by W3C working groups composed of experts and undergo rigorous review and testing to ensure the interoperability and sustainable development of Web technology.

Web standards refer to a set of specifications and best practices followed in web development, aiming to ensure good compatibility and consistency of websites on different browsers and devices. It includes W3C standards, but is not limited to them. Web standards also include specifications and rules developed by other institutions and groups, such as the JavaScript language specification developed by ECMA International, the HTML Living Standard developed by WHATWG, etc.

To understand the difference between W3C standards and Web standards, we can illustrate it through a specific code example.

Suppose we want to create a web page that displays a simple layout with a title and text on the page. Here is a sample code that uses HTML and CSS to implement this layout:

HTML part:

<!DOCTYPE html>
<html>
<head>
  <title>Web标准示例</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <div class="container">
    <h1>欢迎光临</h1>
    <p>这是一个简单的示例网页。</p>
  </div>
</body>
</html>

Copy after login

CSS part (styles.css):

.container {
  text-align: center;
  margin-top: 100px;
}

h1 {
  font-size: 24px;
}

p {
  font-size: 18px;
}

Copy after login

In this example, we HTML is used to define the structure of the page, and CSS is used to specify the style of the page. This complies with the concept of web standards because we follow the HTML and CSS specifications.

At the same time, this example also complies with W3C standards because we use HTML and CSS properties and values that have been standardized by W3C. For example, we use <h1></h1>, <p></p> and other HTML tags, which are clearly defined in the HTML specification. We also use CSS properties such as text-align, margin-top, etc., which are also defined in the W3C standard.

It should be noted that although there is overlap between W3C standards and Web standards, not all code that follows Web standards conforms to W3C standards. Web standards focus more on the consistency and compatibility of the structure and style of web pages, while W3C standards focus more on formulating specifications and standards for various Web technologies.

To sum up, W3C standards are a series of Web technology standards developed and recommended, and Web standards are a set of norms and best practices to be followed. Together, they provide us with the basis for creating Web pages with good compatibility and consistency, and promote the development and progress of Web technology.
