External CSS
External CSS is a method of styling web pages by placing CSS (Cascading Style Sheets) code in a separate file with a .css extension, which is then linked to HTML documents using the <link> tag. This approach separates content (HTML) from presentation (CSS), allowing for consistent styling across multiple pages and easier maintenance. It is a fundamental web development practice for creating scalable and organized websites.
Developers should use External CSS when building multi-page websites or applications to ensure consistent styling, reduce code duplication, and improve maintainability. It is essential for projects where design changes need to be applied globally without editing each HTML file individually, such as in corporate websites, blogs, or e-commerce platforms. This method also enhances performance by enabling browser caching of CSS files.
