What is a key advantage of using CSS?

Using CSS (Cascading Style Sheets) offers several advantages, and one of the most significant is its ability to simplify the formatting of multiple pages within a site. CSS allows developers to define styles for their HTML elements in a centralized way, which means that instead of specifying styles directly within each HTML document, a single CSS file can be created and linked to multiple pages. This results in a consistent look and feel across the entire website, making it easier to manage and update styles.

When a change is needed—such as altering the color scheme or updating the layout—developers can simply modify the CSS file, and all linked pages will reflect the updated styles instantly. This not only saves time and effort but also ensures design consistency, which is crucial for user experience and brand identity.

In addition, CSS enhances loading performance since the browser can cache the CSS file, reducing load times for subsequent page visits. This organizational approach to styling is a fundamental reason why CSS is widely adopted in web development.
