How can you organize custom styles for a Liferay theme?

Organizing custom styles for a Liferay theme using SASS or LESS files and structuring them in folders is an effective approach because it enhances both the maintainability and scalability of the code.

SASS (Syntactically Awesome Style Sheets) and LESS are both preprocessor scripting languages that extend CSS with features like variables, nested rules, mixins, functions, and more. This allows developers to write cleaner, more organized styles that can be divided into smaller, manageable files. By grouping related styles into folders, developers can easily navigate and update their styles as necessary.

Additionally, using a preprocessor allows for more advanced functionalities like inheritance and the ability to maintain a consistent design system across the theme. This organizational strategy aligns well with best practices in front-end development, promoting a modular architecture that can significantly streamline the development process and facilitate collaboration among team members.

The other approaches either compromise the organization of styles or lack the advantages that SASS or LESS offer, making option B the most effective and suitable choice for organizing custom styles in a Liferay theme.
