• <article>: Encapsulates a self-contained piece of content that can be distributed and reused independently, such as a blog post or news article.
• <section>: Groups thematically related content, often accompanied by a heading to describe the section's purpose.
• <aside>: Contains content that is tangentially related to the main content, such as sidebars, pull quotes, or supplementary information.
• <footer>: Represents the footer section of a webpage, typically containing copyright information, contact details, and links to related content or resources.

By incorporating these structural elements into your HTML markup, you can create a well-defined and accessible webpage that is easy to navigate and understand for both users and search engines. In the next sections, we'll explore more HTML5 semantic elements that can further enhance your web content. Stay tuned!

Text-level Semantic Elements

In addition to structural elements, HTML5 introduced several text-level semantic elements that provide meaning and context to inline content. These elements help convey the purpose or significance of specific text fragments within your content. Let's examine some of these text-level semantic elements:

• <mark>: Highlights text that is relevant or important in the current context, such as search results or emphasized phrases.
• <time>: Represents a specific time or date, making it easier for search engines and assistive technologies to understand and process time-related information.
• <abbr>: Defines an abbreviation or acronym, allowing you to provide the full text as a tooltip or for screen readers.
• <cite>: Indicates the title of a cited work, such as a book, article, or film.
• <figcaption>: Provides a caption or description for a <figure> element, which is used to enclose images, diagrams, or other multimedia content.
• <strong>: Emphasizes text with strong importance, often rendered in bold by default.
• <em>: Indicates text with mild emphasis, typically rendered in italics by default.

By using these text-level semantic elements in your HTML markup, you can create richer, more meaningful content that is easier to understand and interpret for both human users and machines. In the upcoming sections, we'll explore more HTML5 semantic elements related to forms, multimedia, and accessibility. Keep going to further enhance your web development skills!
