One of the benefits of using SCSS is that it enables developers to create modular styles for components, which can then be applied across various pieces of website content. This allows for consistent presentation and design throughout, even when an element needs to be used in a different context. Additionally, this type of modularization is especially important for larger websites with multiple brands, as it enables easily-reusable components across the site without needing to make changes or duplications. Not only does this save time and improve efficiency, it also assures uniformity and a polished finished product.
