HTML Semantics

Recap: HTML Buttons and Copywriting

In the previous session, we learned about the power of HTML buttons and how to write effective copywriting that converts visitors into customers. Now, let's dive into the world of HTML Semantics!

What is HTML Semantics?

HTML Semantics involves using HTML elements and attributes in a meaningful and descriptive way that conveys the purpose and structure of your content. Semantic HTML makes it easier for browsers, search engines, and assistive technologies to understand your content.

Benefits of Semantic HTML

  • Improved accessibility for users with disabilities
  • Enhanced search engine optimization (SEO)
  • Easier maintenance and readability of code
  • Future-proof and adaptable for new technologies

How to Write Semantic HTML

Use elements that accurately represent the content and its structure (e.g., <header> for headers, <main> for main content).

  <h1>Main Heading</h1>
  <p>Paragraph content...</p>

Semantic HTML Structure

  • Document structure should be organized logically (<header>, <main>, <footer>)
  • Headings should be used in a hierarchical order (<h1>-<h6>)
  • Use appropriate list elements for ordered (<ol>) and unordered (<ul>) lists

HTML5 Semantic Elements

HTML5 introduced new semantic elements that provide more specific meaning to content:

  • <article>: Represents independent, self-contained content
  • <section>: Defines a section within a document
  • <aside>: Contains content related to, but not part of, the main content
  • <nav>: Defines navigation links within a document

Heading Elements (H1 - H6)

Heading elements are used to structure and organize the content. They convey the importance and hierarchy of the content.

<h1>Main Heading</h1>
<h2>Subheading 1</h2>
<h3>Subheading 2</h3>
<h4>Subheading 3</h4>

Paragraphs (<p>)

Paragraphs represent blocks of text. They are used to convey the main content of a document.

<p>This is a paragraph of text.</p>

Lists (<ul> and <ol>)

Lists are used to organize items in a sequential or unordered manner.

  • Unordered list: <ul>
  • Ordered list: <ol>

Links (<a>)

Links are used to create hyperlinks to other web pages or documents.

<a href="">Example Link</a>

Headings and ARIA Roles

ARIA (Accessible Rich Internet Applications) roles provide additional context to assistive technologies.

<h1 role="heading" aria-label="Main Heading">My Main Heading</h1>

Semantic HTML for Accessibility

Semantic HTML improves accessibility for users with disabilities by providing clear and structured content.

  • Navigating pages with screen readers
  • Understanding page layout for users with cognitive impairments
