Which statement is true about the Liferay Theme Generator's capability regarding themes?

The correct assertion is that the Liferay Theme Generator is specifically designed to create new themes and extend existing ones. It is an essential tool for developers, as it provides a structured way to build themes for Liferay by leveraging technologies like Gulp to automate tasks such as CSS preprocessing and JavaScript minification.

The generator enables developers to not only create completely new themes from scratch but also to make enhancements to existing themes. This includes modifying styles, layouts, and the overall appearance of Liferay's user interface. The functionality to extend themes is a key feature, allowing developers to customize their application to better align with branding or specific design requirements.

While the misconception might arise from a misunderstanding of how the generator operates, it indeed allows for the extension of themes rather than being limited to creating new ones only. Furthermore, there is a robust ecosystem of Gulp tasks compiled within the generator that assists in managing various aspects of the theme development process, contrary to the statement about the absence of gulp tasks associated with themes.
