Web Standards: A Guide to Building Compliant Websites

Building a website that's compliant with web standards is crucial for a smooth user experience. This means following established guidelines to ensure your site is accessible, usable, and compatible with different browsers and devices.

The World Wide Web Consortium (W3C) is the primary organization responsible for setting and maintaining web standards. As of 2022, the W3C has developed over 120 technical specifications for the web, including HTML, CSS, and JavaScript.

Having a clear understanding of web standards can save you time and effort in the long run. By following established guidelines, you can avoid costly rework and ensure your site remains up-to-date with the latest technologies.

Web standards also play a critical role in search engine optimization (SEO). By using semantic HTML and structured data, you can help search engines understand your content and improve your site's visibility in search results.

The W3C and WHATWG are two key organizations involved in developing web standards. The W3C, or World Wide Web Consortium, is an international community that brings together member organizations, a full-time staff, and the public to develop web standards. It was founded in 1994 at MIT in collaboration with CERN.

The W3C's mission is to lead the web to its full potential, led by Web inventor and Director Tim Berners-Lee and CEO Jeffrey Jaffe. At the time of this post, the W3C has 475 member companies and organizations and exists as a consortium between 4 academic institutions. Community groups in the W3C are open to anyone, whether or not their organization is a W3C member.

The WHATWG, on the other hand, was originally a splinter group from the W3C, formed in 2007 due to disagreements over the direction of HTML development. Today, the WHATWG continues to develop and evolve HTML, and many of its members participate in W3C working groups.

The web is built on open standards that make it a unique and exciting industry to get involved in.

These standards are based on three key principles: being open to contribute and use, accessible and interoperable, and not breaking the web.

The web is open to contribute and use, meaning it's not controlled by a single private entity and isn't patent-encumbered.

Standards bodies like the W3C create web standards, and there are others like WHATWG and TC39 that maintain specific standards, such as HTML and ECMAScript.

These standards are created through a process that involves discussing new features with other developers and browser engineers, writing explainer documents and code demos, and evaluating the feature to ensure it's good for the web.

The goal is to implement new features across all browsers without causing existing websites to break.

Here are the key steps in creating a new web standard feature:

1. Someone notices the need for a new web standard feature and discusses it with other developers.

2. The feature is formally discussed inside the relevant standards body working group.

3. The feature is rigorously evaluated to ensure it's good for the web.

4. The feature is implemented across all browsers and can start being used when creating websites.

The web is a collaborative effort, and anyone can contribute to the discussion around new technologies and provide feedback.

Lit-Node is a tool that helps developers create websites that are compatible with multiple browsers, which is crucial for ensuring that websites are displayed correctly across different devices and browsers.

Compliance tests are essential for checking if websites meet web standards. W3C offers online services to test websites directly for developers and users.

Here are some of the compliance tests offered by W3C:

By using these services, developers can identify and fix errors in their code, making it easier to create websites that work across multiple browsers.

Compliance testing can also help reduce development and maintenance time, as it allows developers to focus on creating content that is compatible with multiple browsers, rather than trying to fix issues with individual browsers.

Web standards play a crucial role in ensuring that websites are accessible to everyone, regardless of their abilities. Compliance tests for website code, offered by the W3C, help identify issues with HTML and CSS code, making it easier for developers to fix them.

The Markup Validation Service and CSS Validation Service are two online tools provided by the W3C to test websites for compliance. These services check the markup and CSS of Web documents, helping developers catch errors and improve their code.

Without the Web Standards community, browser makers would have too much control over the web, potentially leading to a monopolized commodity where only the largest players decide what features are available. This could limit access to the web for people with disabilities.

Web standards help standardize the way websites interact with assistive technologies, making it easier for people with disabilities to use the web. By incorporating instructions into their pages, developers can ensure that assistive technologies can interpret and display the content correctly.

Here are some W3C services that help ensure accessibility and compliance:

By using these services and following web standards, developers can create websites that are more accessible and usable for everyone.

Having a website that follows web standards is a game-changer for SEO optimization.

By being compliant with web standards, your website becomes more discoverable by search engines. This is especially true for Google, which uses site crawlers to index and access your site more easily.

Google's site crawlers can figure out what your content is about, where numbered lists are, and what words are on each page. This information helps Google decide which keywords your content is relevant to and where to place your website in its search engine results pages (SERPs).

A web standards compliant website is more likely to be indexed and displayed correctly by search engines, leading to improved browser and search visibility.

Standards are created by people through a culture of consensus, which involves a lot of talking and discussions.

The groups that work on Internet and Web Standards operate under a royalty-free regime, meaning you don't have to pay anyone to use a web standard.

Key Standards Development Organisations (SDOs) in the web space include the Internet Engineering Task Force (IETF), the World Wide Web Consortium (W3C), the WHATWG, and ECMA TC39.

Historically, groups like the Web Standards Project (WaSP) advocated for Web Standards to be adopted by organizations.

The process of creating a standard involves lots of discussions, usually starting as a discussion within a community group or through issues raised on the relevant GitHub repository.

A common theme across different SDOs is ascension, where a discussion moves up within the organization and a deciding committee reaches a consensus to approve its elevation.

Standards are made through a series of approvals and consensus-building, eventually becoming an official standard.

By the time something becomes a standard, it's likely to have already had widespread use across many browsers, and the standard's role is to normalize and facilitate adoption of the new feature.

The history of web standards is a fascinating story. Tim Berners-Lee founded the World Wide Web Consortium (W3C) in 1994 to develop and improve web-based technologies.

The W3C is an international committee that includes businesses, nonprofits, universities, governmental entities, and individuals with full-time staff. This diverse group works together to create internal standards for the web.

In the early days, there were no rules for content creation or site structure, making it difficult for websites to be compatible across browsers. The International Organization for Standardization (ISO) and the European Computer Manufacturers Association (ECMA) later joined the W3C to formalize standards for the web.

The web's history is fascinating, and it's hard to believe how far it's come. In 1994, Tim Berners-Lee founded the World Wide Web Consortium (W3C), an international committee that develops internal standards and improves web-based technologies.

The W3C's work was complemented by the International Organization for Standardization (ISO), which formalizes solutions to global challenges, including environmental and health standards. ISO also identifies international standards across industries, including some aspects of the web.

The European Computer Manufacturers Association (ECMA) joined the effort, setting standards for information and communication systems, such as programming languages and data exchange between systems. This fostered web page interoperability and more.

Before the W3C and these organizations set standards, websites were built without rules for content creation or site structure. Now, developers build websites to meet the same standards, making them compatible across browsers and accessible to as many people as possible.

HTML is one of the most common web standards, used to define the structure and content of web pages.

Cross-site scripting is a common threat to web security, often exploited by hackers to inject malicious code into websites.

HTML is a markup language, not a programming language, which makes it vulnerable to attacks.

Web-focused governing bodies, such as the World Wide Web Consortium (W3C), play a crucial role in setting and maintaining web standards, including HTML.

Cross-site scripting can be prevented by using secure coding practices and validating user input, but it remains a significant threat to web security.

HTML and CSS are the backbone of the web, and understanding their evolution is key to building modern websites.

HTML, or HyperText Markup Language, is the web's publishing language, and developers code every page in it. It has undergone several iterations, with version 2.0 enabling cross-browser functionality, and version 5.0 launching in 2014 and allowing for faster, more complex sites and web applications.

CSS, or Cascading Style Sheets, replaced early HTML style sheet elements and defines the appearance of each component or section. It takes up less file space than old HTML style sheets and is easier to organize, making it a staple for nearly all websites.

HTML is the web's publishing language, and developers code every page in it. It has undergone several iterations, with the most notable being HTML 2.0, which enabled cross-browser functionality.

HTML 3.0 and 3.2 extended the original language, while HTML 4.0 added accessibility options, style sheets, and an improved framework. This made it easier for developers to create complex sites and web applications.

HTML 5.0, launched in 2014, allows for faster and more complex sites and web applications. It's a significant improvement over its predecessors, making it a go-to choice for developers today.

As a developer, I can attest that HTML has come a long way, and its evolution has made it easier to create compatible websites. However, with the rise of multiple browsers, developers still face challenges in making their content compatible across different browsers.

WCAG 2.0 outlines how site creators can make the web more accessible, including adding alt text to images and captions to videos.

The WCAG 2.0 guidelines are also an ISO standard, meaning countries that maintain ISO technical standards should formally adopt these guidelines.

Without web standards, browser makers would be the ones making decisions on what should and shouldn’t be features of the world wide web, potentially leading to a monopolized commodity.

Web standards help to standardize the way in which a website can interact with assistive technologies, making the web a more accessible place.

Incorporating instructions into pages that can be interpreted by assistive technologies maintains a common end-user experience.

Countries that maintain ISO technical standards should formally adopt the WCAG 2.0 guidelines to ensure web accessibility.

ECMA is a standards organization that was founded in 1961 to standardize computer systems in Europe. It's now known as Ecma International, and has become a global organization.

The ECMA-262 standard outlines the ECMAScript Language Specification, which is the standardized specification of the scripting language known as JavaScript. This standard has been published in ten different editions, with the most recent one being released in June 2018.

TC39, or Technical Committee 39, is the group that evolves JavaScript. It's made up of companies that include most of the major browser makers.

The TC39 process involves accelerating proposals through a set of stages, with each stage requiring approval from the committee. Once a proposal has been approved, it becomes an obligation for the member organizations to implement it.

The TC39 operates under a consensus-based model, where agreements are reached through discussion and negotiation. This helps to ensure that all parties are on the same page and that the standard is developed in a way that benefits everyone.
