HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are both essential technologies for web development, but they serve different purposes and have distinct roles. Here are the primary differences between HTML and CSS:

Purpose and Function

HTML (HyperText Markup Language):

• Purpose: HTML is used to create the structure and content of a web page.
• Function: It defines elements such as headings, paragraphs, lists, links, images, and forms.

CSS (Cascading Style Sheets):

• Purpose: CSS is used to control the presentation, formatting, and layout of the web page.
• Function: It defines styles for HTML elements, including colors, fonts, spacing, and positioning.

Syntax and Structure

HTML:

• Syntax: HTML uses tags enclosed in angle brackets (e.g., <h1>, <p>, <a>).
• Structure: HTML elements are nested to create a document structure.

CSS:

• Syntax: CSS uses selectors to target HTML elements and apply styles, enclosed in curly braces {}.
• Structure: CSS rules consist of a selector and a declaration block.

Role in Web Development

HTML:

• Role: Defines the content and basic structure of the web page.
• Usage: Used to add text, images, links, forms, tables, and other content.

CSS:

• Role: Enhances the visual presentation and layout of the web page.
• Usage: Used to style text, arrange content, and create visual effects like animations.

HTML provides the content and structure of a web page, while CSS enhances the appearance and layout. Together, they form the backbone of web design and development, enabling the creation of visually appealing and well-structured websites.
