What language is primarily used for styling web pages?

CSS, or Cascading Style Sheets, is the primary language used for styling web pages. It allows developers to control the layout, colors, fonts, and overall visual appearance of a website independently from its structure, which is typically defined using HTML.

CSS works by applying styles to HTML elements, enabling designers to create visually appealing user interfaces. It uses selectors to target specific elements on a page, which can then be styled using a wide range of properties, such as background-color, font-size, margin, and padding. CSS also supports responsive design, allowing web pages to adapt to various screen sizes and devices.

The other options, while important in web development, serve different functions. HTML is responsible for the structure of a web page, JavaScript is mainly used for dynamic interactivity and behavior, and Python is a general-purpose programming language that is not used for styling web pages. Each of these serves a distinct role in web development, reinforcing the importance of CSS specifically for styling.
