How do CSS preprocessors like SASS or LESS function in Liferay?

CSS preprocessors such as SASS and LESS enhance the capabilities of traditional CSS by introducing advanced features that improve the styling process. One key function of these preprocessors is their ability to use variables, which allow developers to define colors, fonts, or other styles in one place and reuse them throughout their stylesheet. This not only promotes consistency across the design but also simplifies future updates, making it easier to change the look of a website.

Additionally, preprocessors support nesting, allowing developers to write styles in a more hierarchical manner that reflects the structure of HTML. This leads to more organized and maintainable code, especially in larger projects, as it reduces redundancy and can often lead to clearer stylesheets.

While CSS preprocessors do not directly add interactive features to JavaScript, improve database management, or optimize images, they play a crucial role in enhancing the styling capabilities within Liferay, thereby influencing the overall user experience and design quality. By using SASS or LESS, developers can create more dynamic and maintainable styles for their Liferay themes and applications.
