What are the Significant Goals of the HTML5 Specification?
The World Wide Web uses HTML5 as a markup language to organize and display content. It was the first HTML update in 14 years, and it was approved in 2014. In today's world, that's a lifetime between updates. It is the fifth and final major HTML version recommendation issued by the World Wide Web Consortium. The current specification is indeed the HTML living specification.
It now includes support for multimedia, audio, video, tags and elements, improved document markup, and new APIs. HTML5's primary goal is to make it easier for web developers and browser designers to adhere to consensus-based standards that make compliance more efficient and empowering. Additionally, it aims to offer visitors on desktop and mobile devices better, quicker, and more reliable user experiences.
HTML5 was created to be a replacement for HTML4, XHTML, and the HTML DOM Level 2. This new design improves web page structure support with additional tags, ensures more consistent behavior across browsers, improves cross-platform support, and delivers rich content such as movies and graphics without the need for additional plug-ins. All of this not only simplifies design for programmers, but also makes the final design more functional for users.
This version of HTML arose from visible needs in the browser ecosystem, and the specifications' goals are all responses to these needs. The next section discusses HTML5's three primary goals.
Enhancing the Native Web
The World Wide Web Consortium (W3C) specification states that HTML5 introduces APIs and markup for emerging idioms, such as Web apps. It adds syntactic features to the Web that were previously only available through plug-ins. For example, if serving video on the Web is a nearly universal expectation, web browsers should be able to do so without any additional assistance. The same is true for audio and other dynamic or animated content. As a result, the <audio>, <video>, and <canvas> elements are among HTML5's most significant additions to the Web.
HTML5 not only eliminates the need for plug-ins, but it also expands browser functionality to match that of native mobile applications. Browser vendors and standards committees have begun to develop application programming interfaces (APIs) that expose (mobile) device functionality within the browser. The most visible example is the Geolocation API, which allows browsers to retrieve geographical location in the same way that native phone apps do. There are a few smaller niche APIs (for example, one for device orientation) that promise to provide more utility in the browser.
Getting More Done with Less Code
The ability to do more with less code is a much more subtle feature of HTML5. Many de facto standard web page features exist, such as placeholder text in forms, autofocusing on a specific input element when the page loads, client-side validation of form input, date and time pickers, and so on. All of these ideas are considered standard on a modern web page, but they all require at least a little JavaScript to function. As a result, these concepts are implemented in a variety of ways across websites, and are sometimes buggy or inconsistent with one another.
HTML5 simplifies these common design patterns (and others) by establishing standardized methods for achieving them in HTML alone. This empowers designers while also reducing code maintenance and platform interoperability because the browser can handle the functionality of the given feature more contextually.
Semantic WEB
Tim Berners-Lee, the inventor of the World Wide Web, has long desired a semantic web. He imagined a web in which content could not only be read by humans but also understood by machines. Just as we must write carefully for humans to understand, we must also ensure that programmes parsing web pages can detect meaningful content.
HTML5 is the Web's first major semantic push. Web pages can now be marked up so that screen readers, search engines, and other web-crawling software can better understand and categorise them.
There is a lot more to it apart from these major goals. Some of its other objectives include:
The ability to deliver rich content to the client, such as graphics and videos, without the need for additional plugins (i.e., Flash and Silverlight).
Providing a more stringent parsing standard to facilitate error handling and backward compatibility with documents written to older standards.
Providing a better support for web page structure through the introduction of new structural element tags.
