What are HTML Elements and Tags?

An HTML element is a part of an HTML document that describes its structure and content. Elements are defined by tags, which are enclosed in angle brackets (< >). Tags typically come in pairs: an opening tag and a closing tag, with the content placed between them. For example:

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

Here, <p> is the opening tag, </p> is the closing tag, and "This is a paragraph." is the content.

Types of HTML Tags

Container Tags: These tags enclose content and usually come in pairs. For example, <div> </div>, <p> </p>.
Empty Tags: These tags do not enclose content and are self-closing. For example, <br>, <img src="image.jpg" alt="Image Description">.

Basic HTML Tags

Document Structure Tags
- <html>: The root element of an HTML document.
- <head>: This contains metadata, scripts, and links to stylesheets.
- <title>: Sets the title of the web page, shown in the browser tab.
- <body>: Contains the content of the web page.

    <!DOCTYPE html>
    <html>
      <head>
        <title>My First Web Page</title>
      </head>
      <body>
        <h1>Welcome to My Website</h1>
        <p>This is a paragraph of text.</p>
      </body>
    </html>

Text Formatting Tags
- <h1> to <h6>: Header tags for different levels of headings.
- <p>: Paragraph tag.
- <b> and <strong>: Bold text (with <strong> also indicating importance).
- <i> and <em>: Italic text (with <em> indicating emphasis).
- <a>: Anchor tag for creating hyperlinks.

    <h1>This is the Main Heading</h1>
    <p>This is a <strong>bold</strong> paragraph with an <a href="https://google.com">google link</a>.</p>

List Tags

    <ul>

    </ul>

Table Tags

    </form>

Semantic HTML

Semantic HTML introduces tags that describe the meaning of the content they contain, rather than just its appearance. This makes your HTML more readable and accessible. Examples include:

<header>: Represents introductory content or a set of navigational links.
<nav>: Contains navigation links.
<article>: Represents a self-contained piece of content.
<section>: Defines a section in a document.
<footer>: Represents the footer of a document or section.

<article>
  <header>
    <h1>Article Title</h1>
    <p>Published on July 29, 2024</p>
  </header>
  <section>
    <p>This is the content of the article.</p>
  </section>
  <footer>
    <p>Author: Samuel Ojerinde</p>
  </footer>
</article>
