HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are two essential technologies used in web development. They serve different purposes and have distinct roles in creating and styling web pages. Here's the key difference between HTML and CSS:
HTML (Hypertext Markup Language):
Purpose: HTML is the standard markup language used to structure the content of a web page. It defines the elements and layout of the page's content, such as headings, paragraphs, lists, images, links, tables, and more. HTML provides the skeletal structure of a web page, defining what each piece of content is and how it is organized.
Syntax: HTML uses a system of tags to mark up the content. Tags are enclosed in angle brackets (< >) and come in pairs: opening tags (<tag>) and closing tags (</tag>). The content is placed between these tags.
Example:
html
<!DOCTYPE html>
<html>
<head>
<title>My Web Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a paragraph of text.</p>
<img src="image.jpg" alt="Image">
</body>
</html>
In this example, HTML is used to define the page structure, including the title, headings, paragraphs, and an image.
CSS (Cascading Style Sheets):
Purpose: CSS is a style sheet language used to control the presentation and layout of HTML documents. It is used to define the visual appearance of the web page, such as colors, fonts, spacing, positioning, and more. CSS allows developers to separate the design from the content, making it easier to apply consistent styles across multiple pages.
Syntax: CSS uses selectors to target HTML elements and apply styles to them. CSS styles are defined in rules, where each rule consists of a selector and a set of property-value pairs separated by colons (:). CSS can be written inline within HTML elements, placed in a
<style>block in the HTML head, or stored in external CSS files and linked to the HTML document.Example:
css
/* External CSS file */ body { font-family: Arial, sans-serif; background-color: #f0f0f0; } h1 { color: blue; } p { font-size: 16px; line-height: 1.5; }In this example, CSS is used to style the font, colors, and background of the HTML elements.
In summary, HTML is used for structuring the content of a web page, while CSS is used for styling and formatting that content. They work together to create visually appealing and well-structured web pages.
