Which aspect of Liferay allows customization of page layout?

The aspect of Liferay that facilitates the customization of page layout is the theme and layouts. In Liferay, themes provide the visual style of the portal, allowing developers to alter colors, fonts, and overall aesthetics. Layouts, on the other hand, determine the arrangement of content on a page, allowing developers and site administrators to create different structures (like two-column layouts, single-column layouts, etc.) and organize content accordingly. This combination enables a high degree of flexibility in designing pages to meet specific needs or branding requirements.

Themes can include templates and layouts that govern how components are visually presented and interact within the Liferay portal. This means not only can you customize how a page looks, but also how the structure is built to enhance user experience while delivering functionality effectively.

In contrast, permissions management, service builder, and user roles play significant roles in controlling access and defining user capabilities within the portal environment, but they do not directly influence the customization of the visual aspect or layout of pages. These other functionalities serve different purposes within the broader Liferay ecosystem.
