Using a Full Site Editing (FSE) theme in WordPress offers significant advantages over classic themes. FSE themes provide unparalleled design flexibility by allowing customization of the entire site structure through a user-friendly block-based editor. This intuitive editing process includes real-time previews and ensures consistency across all pages, saving time and effort. FSE themes also come with pre-designed block patterns and templates, fostering efficient workflows and aiding users with varying design expertise. As WordPress evolves towards a more block-centric approach, choosing an FSE theme ensures adaptability to future updates, and the themes are inherently responsive, delivering a modern and streamlined design experience.
