Introduction to HTML Elements and Tags
HTML, which stands for HyperText Markup Language, is the backbone of web pages. It uses elements and tags to structure content. Think of HTML as the skeleton of a webpage, giving it shape and form.
Core Concepts
Let’s break down some key terminology:
- Tag: A tag is a piece of code that tells the browser how to display content. Tags are enclosed in angle brackets, like
<tagname>. - Element: An element is a complete set of tags and the content between them. For example,
<p>Hello, World!</p>is a paragraph element.
💡 Lightbulb Moment: Tags are like the instructions, and elements are the complete package!
Simple Example
<!DOCTYPE html>
<html>
<head>
<title>My First Page</title>
</head>
<body>
<h1>Welcome to My Webpage</h1>
<p>This is a simple paragraph.</p>
</body>
</html>This example shows a basic HTML document:
<!DOCTYPE html>declares the document type.<html>is the root element.<head>contains meta-information like the title.<body>is where your visible content goes.
Expected Output: A webpage with a title ‘My First Page’ and a heading ‘Welcome to My Webpage’ followed by a paragraph.
Progressively Complex Examples
Example 1: Adding More Content
<!DOCTYPE html>
<html>
<head>
<title>My Enhanced Page</title>
</head>
<body>
<h1>Welcome to My Webpage</h1>
<p>This is a simple paragraph.</p>
<p>Here is another paragraph with more information.</p>
</body>
</html>We’ve added another paragraph to give more information. Notice how each paragraph is wrapped in <p> tags.
Example 2: Using Lists
<!DOCTYPE html>
<html>
<head>
<title>My List Page</title>
</head>
<body>
<h1>My Favorite Fruits</h1>
<ul>
<li>Apple</li>
<li>Banana</li>
<li>Cherry</li>
</ul>
</body>
</html>This example introduces an unordered list using <ul> and list items with <li>.
Example 3: Adding Links
<!DOCTYPE html>
<html>
<head>
<title>My Link Page</title>
</head>
<body>
<h1>Check Out My Favorite Site</h1>
<p>Visit <a href='https://www.example.com'>Example.com</a> for more information.</p>
</body>
</html>Here, we’ve added a hyperlink using the <a> tag. The href attribute specifies the URL.
