SlowlyRegeneration
Rebuild the generated CSS and HTML when you need a clean pass.
Slowly writes the CSS for a page, and the HTML for some blocks, when you save it in the editor. That happens automatically; you do not normally need to touch this panel.
Regeneration re-runs that generation for every post, template, and stylesheet on the site in one pass, rather than one at a time as each gets saved. Reach for it after a bulk change that saving each item individually would not practically cover: restoring content from an import or a backup, updating Slowly itself, or toggling a setting that changes how blocks mark up (for example, removing IDs and classes). It is bulk repair, not a routine step.
Slowly → Settings → Regeneration has these buttons:
| Button | What it does |
|---|---|
| Blocks HTML | Re-serializes every post, template, and reusable block through each block's own save function, rewriting the stored markup. Use it after a change that affects how blocks save, not how they render, such as a class or ID cleanup. |
| Blocks CSS | Rebuilds the per-post CSS for every post, template, and reusable block from their current block attributes. Use it if front-end styling looks stale across many pages at once, after a bulk content restore for instance. |
| Global Classes CSS | Rebuilds the stylesheet for your global classes from their current definitions. Use it if a global class stops matching what its editor panel shows. |
| Global Styles CSS | Rebuilds the site-wide stylesheet (the active global style and its presets). Use it after editing global styles somewhere that did not trigger its own save. |
| Purge Tailwind CSS | Reruns the Tailwind purge over every post so the shipped stylesheet only contains classes actually in use. Only shown when Tailwind is active. |
Each button processes content in chunks and reports progress, then a success or error toast. Global Classes CSS and Global Styles CSS both refuse to write an empty stylesheet over an existing one, so a run that comes back empty cannot blank your site's styling.
