It's not practical to explain every HTML tag in a single response, as there are a large number of them, and their usage can depend on the specific requirements of a web page. However, I can provide an overview of some common HTML tags and their purposes:
1. **Document Structure:**
- `<html>`: The root element of an HTML document.
- `<head>`: Contains meta-information about the HTML document, such as title, links to stylesheets, etc.
- `<title>`: Sets the title of the HTML document.
2. **Text Markup:**
- `<h1>`, `<h2>`, `<h3>`, ..., `<h6>`: Headings of decreasing importance.
- `<p>`: Paragraph.
- `<br>`: Line break.
- `<strong>`: Strong importance, often represented as bold.
- `<em>`: Emphasis, often represented as italic.
3. **Lists:**
- `<ul>`: Unordered list.
- `<ol>`: Ordered list.
- `<li>`: List item.
4. **Links and Navigation:**
- `<a>`: Anchor, used for hyperlinks.
- `<nav>`: Represents a section of navigation links.
5. **Images:**
- `<img>`: Embeds an image.
6. **Tables:**
- `<table>`: Defines a table.
- `<tr>`: Defines a table row.
- `<th>`: Defines a table header cell.
- `<td>`: Defines a table data cell.
7. **Forms:**
- `<form>`: Defines an HTML form for user input.
- `<input>`: Defines an input field.
- `<textarea>`: Defines a multiline text input.
- `<select>`: Defines a dropdown list.
- `<button>`: Defines a clickable button.
8. **Semantic HTML:**
- `<article>`, `<section>`, `<aside>`, `<header>`, `<footer>`, `<main>`: Semantic tags that define the structure of a page for better accessibility and SEO.
9. **Multimedia:**
- `<audio>`: Embeds sound content.
- `<video>`: Embeds video content.
10. **Embedded Content:**
- `<iframe>`: Embeds an external resource, typically another web page.
11. **Metadata:**

These are just a few examples, and there are many more HTML tags available. The specific tags you use will depend on the content and structure of your web page. Additionally, the HTML specification is periodically updated, so new tags may be introduced over time. If you have a specific tag in mind or need information about a particular aspect of HTML, feel free to ask!
