CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML.
- CSS allows you to control the layout of multiple web pages all at once, saving a lot of work.
- It enables the separation of content from design, making maintenance easier and providing more flexibility in presentation.
- CSS enhances the accessibility of web pages by allowing for responsive designs that adapt to different screen sizes and devices.
Here are some key applications of CSS:
1. Styling Web Pages: CSS allows for the application of various styles to HTML elements, including fonts, colors, and layouts, enhancing the visual appeal of web pages.
2. Responsive Design: By using media queries, CSS enables web pages to adapt to different screen sizes and devices, ensuring a consistent user experience across platforms.
3. Consistency Across Pages: External CSS files can be linked to multiple HTML documents, allowing for uniform styling across a website and simplifying maintenance.
4. Accessibility Improvement: CSS facilitates the creation of accessible web content by allowing adjustments in presentation without altering the underlying HTML, catering to users with diverse needs.
5. Animation and Interactivity: CSS supports animations and transitions, enabling interactive elements without relying solely on JavaScript

In this example,
- The <meta name="viewport" content="width=device-width, initial-scale=1.0"> tag ensures the page scales correctly on different devices.
- The CSS within the <style> tag styles the page and includes a media query that adjusts the layout for screens narrower than 600 pixels.
