Every block, and the toolbar
Updated 2026-08-13
A reference for two questions: which block do I want, and what is that button at the top for. For how to add and arrange them, see Working with blocks.
Writing
HeadingSection titles. They are the page’s structure, so do not use one just to make text big.
TextParagraphs. Takes
{{ }} tokens and wiki links.CalloutA boxed aside: a warning, a tip, a spoiler.
QuoteAn attributed quotation.
Section headerA heading with an eyebrow and subtitle, for a band of page.
Layout
These hold other blocks, and between them build every arrangement on a page.
Box / CardThe general container. A card, a panel and a coloured band are all this.
ColumnsSide by side. Stacks on a phone by itself.
TabsSeveral panels in the space of one. Bad for anything a reader needs to compare.
AccordionCollapsed sections. The FAQ block.
SpacerVertical room, when a margin genuinely will not do. Usually it will.
DividerA rule between sections.
HeroA full-width opener with art behind it.
Pictures and media
ImageOne picture, with an optional caption and link.
GallerySeveral, as a grid.
LightboxA picture that opens full-size when clicked.
VideoA clip, or an embed from a video host.
IconOne symbol from the icon set, at a size and colour you set.
Data
These read a table. Most need the page bound to a row and render nothing without one, which is the usual reason a data block looks empty.
Field textOne column value, inline in a sentence.
Data valueOne value with a label, a prefix and a suffix.
InfoboxThe summary panel: a picture and a stack of label/value rows.
Stat tableA table built from columns of the bound row.
Dataset grid / list / CollectionMany rows, as cards or a list. The block behind an index page.
Data repeaterOne block repeated per row, when the built-in lists are not the shape you want.
RelatedOther entries near this one.
ConditionalBlocks that only appear when the row warrants it. Read on.
Page parts
These exist for the page frame and shared layouts, not for ordinary pages.
Page content slotWhere a page's own blocks flow into a template. Decides whether a block belongs to every entry or just this one.
Page body slotWhere the whole page goes inside the frame.
Title / Breadcrumbs / CategoriesThe standard furniture, as blocks you can move rather than fixed chrome.
Interactive
Reader inputA control a reader changes, feeding a calculation. See Variables and formulas.
Search barSearch, placed on a page.
Copy buttonCopies a value to the clipboard.
ButtonA link that looks like a button.
Sponsor slotAn advert placement. See Sponsors and ads.
Beyond these, extensions add their own, grouped under their own name in the palette.
The toolbar, button by button
Desktop / Tablet / PhoneThe canvas becomes that width. The real breakpoints, not a simulation.
Blocks / LayersThe palette, or the page as a tree. Layers is how you select something buried in three boxes.
Block outlinesA hairline around every block, so you can see where one ends.
Spacing guidesEach block’s padding and margin, with numbers. Turn it off and the canvas is just the page.
Wiki CSSThe wiki-wide stylesheet, editable without leaving the page. Custom CSS
Undo / RedoOr Ctrl+Z. Everything on the canvas is undoable.
PreviewThe page exactly as a reader gets it, including unsaved changes.
SaveWrites a new version. It says whether that goes live or becomes a proposal before you press it.
More optionsRestore an earlier version, discard your changes, and the page's own settings.
