What is CSS?
CSS (Cascading Style Sheets) is a stylesheet language used for describing the presentation of a document written in HTML or XML. It controls the layout, colors, fonts, and overall visual appearance of web pages.
Key Features of CSS
- Styling: Defines the visual appearance of HTML elements.
- Selectors: Allows targeting of specific HTML elements for styling.
- Box Model: Provides a framework for layout control, including margins, borders, padding, and content.
- Media Queries: Enables responsive design by applying different styles based on device characteristics.
How Does CSS Work?
CSS works by applying styles to HTML elements based on selectors. Styles are defined in a CSS file or within HTML using the <style> tag. The browser parses the CSS and applies the defined styles to the matching HTML elements, rendering the webpage according to the specified design.
Best Practices for Using CSS
- Organize Styles: Use separate CSS files for better organization and maintainability.
- Use Classes and IDs: Apply classes and IDs for reusable and specific styling.
- Responsive Design: Implement media queries for responsive design.
- Minimize Inline Styles: Avoid inline styles to keep HTML clean and maintainable.
