When you visit a website, what you see on the screen is the result of two key technologies working together: HTML (HyperText Markup Language) and CSS (Cascading Style Sheets). Together, they form the foundation of every website you browse. Let’s dive into what they are and how they work.


What is HTML?

HTML is the backbone of web pages. It defines the structure and content of a webpage using elements, which are written as tags enclosed in < >. For example:

<!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>

Key Features of HTML:

  • Elements: Represent content like headings (<h1>), paragraphs (<p>), images (<img>), and links (<a>).
  • Attributes: Provide additional information about an element, e.g., <a href="https://example.com">Link</a>.
  • Structure: Organizes content into sections using elements like <header>, <footer>, <section>, etc.

What is CSS?

CSS controls the style and appearance of the webpage. It determines how HTML elements look: their colors, fonts, spacing, and layout. Here’s an example of how CSS works:

/* Styles for the webpage */
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
color: #333;
}
h1 {
color: #4CAF50;
text-align: center;
}
p {
line-height: 1.6;
}

Key Features of CSS:

  • Selectors: Target specific HTML elements to style (e.g., body, h1, p).
  • Properties: Define the styles, like color, font-size, or margin.
  • Responsiveness: Helps websites adapt to different screen sizes using techniques like media queries.

How Do HTML and CSS Work Together?

HTML provides the structure, while CSS enhances its appearance. For example:

HTML:

<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>My Styled Website</h1>
<p>This paragraph will look great with CSS!</p>
</body>
</html>

CSS (in styles.css):

h1 {
color: blue;
font-size: 2em;
}
p {
font-style: italic;
color: gray;
}
