HTML
HTML, or Hypertext Markup Language, is the standard markup language for creating web pages and web applications. It provides the structure and layout of a webpage by using a system of tags and attributes to define elements and their relationships.
-  Markup Language: - HTML is a markup language, meaning it uses tags to define elements within a document.
- Tags are enclosed in angle brackets (< >) and are used to indicate the beginning and end of elements.
 
-  Structure: - HTML documents are structured as a hierarchy of elements, with each element representing a different part of the document.
- Elements can be nested within other elements, creating a tree-like structure.
 
-  Content: - HTML supports various types of content, including text, images, videos, links, forms, and more.
- Content is placed within the appropriate HTML elements using tags, such as; - <p>for paragraphs,
- <img>for images,
- <video>for videos,
- <a>for links,
- <form>for forms.
 
 
-  Attributes: - HTML elements can have attributes, which provide additional information about the element.
- Attributes are added to the opening tag of an element and are used to modify the element’s behavior or appearance.
 
Examples
Here’s an example of HTML code that creates a simple webpage with a heading, paragraph, and an image:
<!DOCTYPE html>
<html>
  <head>
    <title>Programming Handbook</title>
  </head>
  <body>
    <h1>Welcome to the Programming Handbook</h1>
    <p>This is a paragraph of text.</p>
    <img src="example.jpg" alt="An example image" />
  </body>
</html>
Conclusion
HTML is essential for creating the structure and content of web pages and web applications.
