HTML Secrets: Enhance Your Web Pages with These Overlooked Tags

HTML is the fundamental language used in web development to create online pages. Common HTML tags like <div>, <p>, <a> and <img> are well-known to developers, but there are a number of lesser-known but equally useful elements, offering thorough explanations and code samples to assist you in successfully using them in your applications.

HTML Tags:

1. <article>

Introduced in HTML5, the <article> tag is a semantic element. Its purpose is to hold an autonomous, reusable, and self-contained piece of material. A blog post, news story, forum post, or any other type of information that stands alone might be used for this.

Example:

<article>
  <header>
    <h1>Understanding the Basics of HTML</h1>
    <p>By Jane Doe, Published on May 27, 2024</p>
  </header>
  <p>HTML, or HyperText Markup Language, is the standard language used to create web pages...</p>
  <footer>
    <p>Posted in Web Development</p>
  </footer>
</article>

Using <article> helps search engines and screen readers understand that the enclosed content is a distinct section that can stand alone, improving SEO and accessibility.

2. <aside>

The <aside> tag is used to represent content that is tangentially related to the content around it. This could include sidebars, pull quotes, advertisements, or other content that isn’t the main focus but provides additional information.

Example:

<main>
  <article>
    <h2>Main Content</h2>
    <p>This is the main content of the page...</p>
  </article>
  <aside>
    <h3>Related Articles</h3>
    <ul>
      <li><a href="#">How to Use HTML5 Semantic Tags</a></li>
      <li><a href="#">Improving Web Accessibility with HTML</a></li>
    </ul>
  </aside>
</main>

The <aside> element helps in separating supplementary content from the main content, making the structure of the webpage clearer for users and assistive technologies.

3. <details> and <summary>

The <details> and <summary> tags are used together to create expandable content. This is particularly useful for FAQs, where users can click to reveal more information.

Example:

<details>
  <summary>What is HTML?</summary>
  <p>HTML stands for HyperText Markup Language. It is the standard language for creating web pages.</p>
</details>
<details>
  <summary>What are HTML tags?</summary>
  <p>HTML tags are the building blocks of HTML, used to create elements like headings, paragraphs, links, and images.</p>
</details>

These tags enhance user experience by allowing users to control what information they want to see, reducing clutter on the page.

4. <figure> and <figcaption>

The <figure> tag is used to group media content like images, diagrams, or code snippets, while <figcaption> provides a caption for the content within <figure>.

Example:

<figure>
  <img src="html-structure.png" alt="Diagram of HTML structure">
  <figcaption>Figure 1: Diagram of a basic HTML document structure</figcaption>
</figure>

Using <figure> and <figcaption> helps in semantically grouping related content and providing context, which is beneficial for accessibility and SEO.

5. <mark>

The <mark> tag is used to highlight text that has a relevant context or is of special interest.

Example:

<p>The term <mark>HTML5</mark> refers to the fifth and current major version of HTML.</p>

The <mark> tag helps draw attention to specific parts of text, making it useful for highlighting search terms or important information.

6. <time>

The <time> tag is used to represent dates, times, or durations in a machine-readable format, which is useful for events, articles, and other time-based content.

Example:

<article>
  <header>
    <h1>Upcoming Web Development Conference</h1>
    <p><time datetime="2024-06-15T09:00">June 15, 2024, at 9:00 AM</time></p>
  </header>
  <p>Join us for a day of insightful talks and networking...</p>
</article>

The <time> element helps browsers and search engines understand the temporal context of the content, which can improve search engine results and enable features like event reminders.

7. <meter>

The <meter> tag is used to represent a scalar measurement within a known range, making it ideal for displaying things like disk usage, voting results, or any other numerical value within a range.

Example:

<label for="disk-usage">Disk Usage:</label>
<meter id="disk-usage" value="60" min="0" max="100">60%</meter>

The <meter> tag provides a visual representation of a measurement, improving user experience by making data more accessible and understandable at a glance.

8. <progress>

The <progress> tag is used to represent the completion progress of a task, such as downloading a file or filling out a form.

Example:

<label for="file-upload">File Upload:</label>
<progress id="file-upload" value="32" max="100">32%</progress>

The <progress> element gives users a visual cue about the progress of a task, enhancing usability by providing immediate feedback.

9. <output>

The <output> tag represents the result of a calculation or user action, often used with forms to display dynamic results.

Example:

<form oninput="result.value=parseInt(a.value)+parseInt(b.value)">
  <input type="number" id="a" value="0"> +
  <input type="number" id="b" value="0">
  <output name="result" for="a b">0</output>
</form>

The <output> element is useful for dynamically displaying results based on user input, making forms more interactive and user-friendly.

10. <datalist>

The <datalist> tag is used to provide a list of predefined options to an <input> element, enhancing the user experience with type-ahead suggestions.

Example:

<label for="browser">Choose your browser:</label>
<input list="browsers" id="browser" name="browser">
<datalist id="browsers">
  <option value="Chrome">
  <option value="Firefox">
  <option value="Safari">
  <option value="Edge">
  <option value="Opera">
</datalist>

Using <datalist> enhances forms by providing users with suggestions, reducing the chances of errors and speeding up the input process.

11. <abbr>

The <abbr> tag is used to define abbreviations and acronyms, providing a full form on hover, which is useful for improving accessibility and user understanding.

Example:

<p>The <abbr title="World Health Organization">WHO</abbr> released new guidelines on health and safety.</p>

The <abbr> element helps clarify abbreviations and acronyms, ensuring that all users, including those using assistive technologies, can understand the content.

12. <kbd>

The <kbd> tag is used to represent user input, typically from a keyboard, making it useful for documenting software instructions or commands.

Example:

<p>To save your work, press <kbd>Ctrl</kbd> + <kbd>S</kbd>.</p>

The <kbd> element makes instructions involving user input more readable and visually distinct, improving the user experience.

13. <samp>

The <samp> tag is used to represent sample output from a computer program, often used in conjunction with <kbd> to show input and output together.

Example:

<p>Enter your name in the terminal and press <kbd>Enter</kbd>:</p>
<pre>
<kbd>$</kbd> <samp>John Doe</samp>
</pre>

Using <samp> helps clearly differentiate between user inputs and program outputs, enhancing readability and comprehension.

14. <code>

The <code> tag is used to define a fragment of computer code, often used to highlight code snippets within a paragraph.

Example:

<p>To create a new function in JavaScript, use the <code>function</code> keyword.</p>

The <code> element provides a semantic way to highlight code snippets, making technical content more accessible and easier to read.

15. <pre>

The <pre> tag is used to display preformatted text, preserving whitespace and line breaks, making it ideal for code blocks and poems.

Example:

<pre>
function greet(name) {
  console.log('Hello, ' + name + '!');
}
greet('World');
</pre>

Using <pre> ensures that text is displayed exactly as written, maintaining the intended formatting and structure, which is crucial for readability in technical documentation.

16. <var>

The <var> tag is used to define a variable

in programming or mathematical expressions, making it useful for educational and technical content.

Example:

<p>The formula for calculating the area of a circle is <code>A = πr<sup>2</sup></code>, where <var>r</var> is the radius.</p>

The <var> element helps differentiate variables from other text, enhancing the clarity of mathematical and programming content.

17. <cite>

The <cite> tag is used to reference the title of a work, such as a book, article, or research paper, often used to give credit to sources.

Example:

<p>According to <cite>The World of Web Development</cite>, HTML is the foundation of web design.</p>

Using <cite> provides a clear and semantic way to reference sources, improving the credibility and traceability of information.

18. <address>

The <address> tag is used to provide contact information, typically for the author of the document or an organization.

Example:

<address>
  <p>Contact us at:</p>
  <p>Web Development Inc.<br>
  123 Web Street<br>
  Code City, Tech State, 12345</p>
</address>

The <address> element helps semantically group contact information, making it easier for users and search engines to identify.

19. <small>

The <small> tag is used to represent fine print or disclaimers, typically for legal notes or additional information that is less important.

Example:

<p>All prices are subject to change without notice. <small>Terms and conditions apply.</small></p>

Using <small> helps de-emphasize less critical information, ensuring that the main content remains the focal point while still providing necessary details.

20. <bdi> and <bdo>

The <bdi> (Bi-Directional Isolation) tag is used to isolate a part of text that might have a different text direction from the surrounding content, while <bdo> (Bi-Directional Override) overrides the current text direction.

Example:

<p>Usernames in different languages: <bdi>اسم المستخدم</bdi> and <bdi>ユーザー名</bdi></p>
<p>Text direction override: <bdo dir="rtl">This text will be displayed from right to left.</bdo></p>

Using <bdi> and <bdo> helps manage text direction effectively, which is crucial for multilingual content and ensuring correct display.
