What Is the Key Difference Between HTML and CSS?

Hello, web development enthusiasts!

Are you new to the world of web development and wondering what the key difference between HTML and CSS is? Understanding these two fundamental technologies is essential for anyone looking to create beautiful and functional websites. In this article, we’ll break down the basics of HTML and CSS, highlighting their unique roles and how they work together to bring web pages to life.

HTML: The Structure of a Web Page

What Is HTML?

HTML stands for HyperText Markup Language. It is the standard language used to create and structure the content of web pages. Think of HTML as the skeleton of a web page; it provides the basic structure and layout.

What Does HTML Do?

HTML is responsible for:

Defining Content: It structures text, images, videos, links, and other multimedia elements.
Creating Layouts: It uses elements like <header>, <nav>, <section>, <article>, and <footer> to organize content.
Adding Links: It uses anchor tags (<a>) to create hyperlinks that connect different web pages.
Embedding Media: It allows the inclusion of images (<img>), videos (<video>), and other media.

Example of HTML Code

Here’s a simple example of an HTML document:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First Web Page</title>
</head>
<body>
    <header>
        <h1>Welcome to My Website</h1>
    </header>
    <main>
        <p>This is a paragraph of text on my first web page.</p>
        <img src="image.jpg" alt="A beautiful scenery">
    </main>
    <footer>
        <p>© 2024 My Website</p>
    </footer>
</body>
</html>

CSS: The Style of a Web Page

What Is CSS?

CSS stands for Cascading Style Sheets. It is the language used to style and design web pages. If HTML is the skeleton, CSS is the skin, clothes, and makeup that make a web page look visually appealing.

What Does CSS Do?

CSS is responsible for:

Styling Text: It sets fonts, colors, sizes, and other text properties.
Designing Layouts: It controls the positioning, margins, padding, and overall layout of elements.
Adding Colors and Backgrounds: It applies colors, gradients, and background images.
Enhancing User Experience: It creates hover effects, transitions, and animations.

Example of CSS Code

Here’s an example of a CSS file that styles the HTML document above:

body {
    font-family: Arial, sans-serif;
    background-color: #f5f5f5;
    margin: 0;
    padding: 0;
}

header {
    background-color: #333;
    color: white;
    text-align: center;
    padding: 20px;
}

main {
    padding: 20px;
}

p {
    font-size: 16px;
    color: #333;
}

img {
    max-width: 100%;
    height: auto;
}

footer {
    background-color: #333;
    color: white;
    text-align: center;
    padding: 10px;
}
