1. Semantic Tags in HTML
In this chapter, we will explore semantic tags in HTML. Semantic HTML refers to the use of HTML5 elements that clearly describe their meaning in a human- and machine-readable way. This chapter will demonstrate the importance of semantic tags using the <details> and <summary> tags as an example.
2. What are Semantic Tags?
Semantic tags are elements that not only define the structure of a webpage but also clearly describe the role and purpose of the content they enclose. For instance, tags like <header>:, <footer>, <article>, and <section> provide meaning to both the developer and the browser, making the code easier to read and improving SEO (Search Engine Optimization).
Here’s a real-world example of semantic tags in action.

<h2>Introduction to Semantic HTML</h2>
<p>Semantic HTML is all about writing code that describes its content clearly. It improves both the
accessibility and SEO of your website. One great example of a semantic element is the
<code><details></code> tag, which can be used to create interactive disclosure widgets.</p>

<h2>Using the <details> and <summary> Tags</h2>
<p>The <code><details></code> tag is used to hide content that users can reveal on demand. It's
perfect for FAQs, where you want users to click and reveal more information.</p>

<summary>Click to learn more about semantic tags</summary>
<p>Semantic HTML refers to the use of HTML elements that convey meaning in a clearer way. It allows
search engines and assistive technologies like screen readers to better understand the structure and
purpose of your content. For example, the <code><details></code> element creates an interactive
widget that users can open and close, while the <code><summary></code> tag defines a visible
heading that the user clicks on.</p>
</details>
</article>
</section>

4. Explanation
<section> : This tag is used to group content into thematic sections. Inside it, we use <article> elements to represent different pieces of content, such as an introduction and a description of the details and summary tags.
<details> : The <details> element creates an interactive widget where the user can hide or show additional content. This can be used for FAQs, tutorials, and more.
<summary> : The <summary> element defines the title for the <details> widget. When clicked, it reveals the hidden content enclosed within the <details> tag. In this case, the summary provides a short sentence that invites the user to click and learn more about semantic tags.
<p> : The <p> element represents a paragraph of text. Inside the details section, it provides more detailed information once the summary is clicked.

5. Why Use Semantic Tags?
Accessibility: Semantic HTML elements like <header>, <footer>, <section>, and <article> make your code more accessible to screen readers and other assistive devices, allowing users with disabilities to navigate your content more easily.
SEO Benefits: Search engines like Google use semantic tags to better understand the structure and hierarchy of your webpage. This can lead to improved rankings in search results.
Maintainability: Code that uses semantic elements is easier to read and maintain, making it simpler for developers to collaborate on projects and make updates later.
User Experience: Using elements like <details> and <summary> can improve user experience by making content more interactive and organized, allowing users to expand or collapse sections of information based on their needs.
