HTML5
HTML describes the structure and meaning of webpage content. It defines headings, links, images, forms, and media so browsers and assistive technologies can present and navigate a page.

HTML marks each part of a page according to its purpose, such as a heading, navigation area, image, or form control. Browsers turn that document into a navigable interface. The current HTML standard is maintained as a living standard, while HTML5 remains a familiar label for modern web markup.
What you can build
Build the foundations of websites, articles, contact forms, and multimedia pages, usually alongside CSS and JavaScript.
Accessible information page
Organize headings, navigation, images, and links so visitors can find content visually or with assistive technology, including when presentation styles are unavailable.
Structured contact form
Use appropriate labels and input types to collect information clearly, then connect the form to server processing and helpful feedback for its users.
Things to consider
Choosing elements by their meaning gives CSS and JavaScript a stronger foundation. Useful alternative text, labels, heading order, and valid links still require deliberate authoring.
