What coding language is primarily used for styling web pages?

The primary coding language used for styling web pages is CSS, which stands for Cascading Style Sheets. CSS is specifically designed to control the presentation layer of web content, which includes aspects such as layout, colors, fonts, and overall look and feel of a webpage. By separating presentation from HTML, CSS allows for greater flexibility and control over the appearance of a site, enabling developers to apply styles consistently across multiple pages and elements without the need to repeat styling rules.

HTML, while fundamental for structuring content on the web, does not provide the styling capabilities that CSS offers. JavaScript is a programming language primarily used for creating dynamic and interactive elements on web pages, while PHP is a server-side scripting language used for backend development. Although both JavaScript and PHP play important roles in web development, they do not serve the purpose of styling web pages as CSS does. Therefore, CSS stands out as the correct choice for the language dedicated to styling web content.
