Block type styles provide the most specific level of styling in your hierarchy, but use them sparingly after establishing solid base and element styles. Most design needs should be satisfied by the broader styling layers.
Access block styling through the styles sidebar’s blocks section, where you can search for specific blocks or browse the complete list. Common use cases include styling post titles differently from body links, or creating unique navigation treatments.
Be aware of limitations with complex blocks like navigation that contain multiple inner block types. Rather than styling each inner block individually, consider using element styles within the block scope through theme.json for more efficient management.
The interface includes an Advanced section for adding custom CSS, but this should be used sparingly. For substantial custom styling, create proper block style variations with dedicated stylesheets rather than inline CSS strings.
