For developers
Filters, action hooks, custom code, and custom CSS.
Slowly gives developers the usual ways in.
- Filters and actions let you change behaviour and output in PHP, the WordPress way.
- Custom code in Settings adds snippets to the head or body of the site.
- Custom CSS can be written per block in the Advanced tab, or kept in a stylesheet with the rest of your design.
- The Code and Hook blocks drop logic or hooked output straight into a layout.
Who can reach the code-running parts is set in the Role Editor.
