BB Codes

BB code is a lightweight markup language for formatting posts. Each tag is wrapped in square brackets — like HTML but safer and simpler. The editor toolbar inserts them for you; knowing the syntax just helps you type faster.

5Advanced

  • Hide selected content from users below a level using the [HIDE] family of tags, if enabled by the admin.
  • Custom BB codes created by the admin appear in the editor toolbar and on this page as the set grows.

Formulas (LaTeX)

Write the formula in TeX between the tags; the board draws it with KaTeX. The formula button in the editor opens a dialog with a live preview.

  • [math]x^2 + y^2 = z^2[/math] on a line of its own is a display formula (large, centred); inside a sentence it stays inline.
  • [math=display]…[/math] and [math=inline]…[/math] choose the form; [imath]…[/imath] is always inline; [latex]…[/latex] works like [math].
  • When the board allows it, text between $$ … $$ or \[ … \] is drawn as a display formula (it may span several lines) and \( … \) as an inline one.
