HTML: Tags, Attributes, and Semantic Elements Overview

HTML: A Guide to Tags, Attributes, and Semantic Elements

HTML, the HyperText Markup Language, is the fundamental framework for building websites and web applications. In this article, we'll explore essential HTML elements and attributes, focusing on tags, attributes, forms, tables, and semantic elements.

Tags

HTML elements are defined by opening and closing tags. For example:

<h1>Heading 1</h1>

Attributes

Attributes provide additional information about elements. For example, class and id are common attributes used to select elements with CSS:

<div class="container" id="main">...</div>

Forms

Forms enable user input using input fields, buttons, and more:

<form action="/submit-form" method="post">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name">
  <input type="submit" value="Submit">
</form>

Tables

Tables facilitate structured data presentation:

<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>John</td>
      <td>25</td>
    </tr>
    <tr>
      <td>Jane</td>
      <td>30</td>
    </tr>
  </tbody>
</table>

Semantic Elements

Semantic elements provide more meaningful structure, which improves accessibility and search engine optimization:

<article>
  <h1>A New Article</h1>
  <p>This article explains HTML basics.</p>
  <footer>
    <p>Published on January 1, 2022.</p>
  </footer>
</article>

Relevant Attributes

• address: Provide author information.
• footer: Add extra information at the end of an element.
• time: Specify the date and time of publication.
