W3C Standards are guidelines and specifications created by the World Wide Web Consortium to ensure the long-term growth of the web. These standards help developers create websites and applications that work consistently across different devices and browsers, promoting accessibility and interoperability. By following W3C Standards, developers can enhance user experience and ensure that their content is accessible to everyone, including people with disabilities. These standards cover various aspects of web development, including HTML, CSS, and XML, making it easier for developers to build reliable and efficient web solutions.
