What is one main benefit of using cascading style sheets (CSS) in web design?

One main benefit of using cascading style sheets (CSS) in web design is that it enables consistent styling across multiple pages. By defining styles in a single CSS file, web designers can apply uniform formatting and design elements—such as colors, fonts, and layout structures—to all pages of a website. This consistency not only enhances the overall visual appeal of the site but also simplifies maintenance. When changes are required, such as altering a font or color scheme, they can be made in one central location rather than updating each HTML document individually. Consequently, this approach promotes efficiency in design and ensures that all pages present a cohesive look and feel, which is essential for user experience and branding.
