The visual editor and Publishing API use the same content rules. Supported formatting remains stable in drafts, published articles, translations and revisions.

Everyday formatting

  • Use H2 and H3 for sections; the article title is stored separately.
  • Use the visible buttons for emphasis, quotations, lists, dividers, links, videos and images.
  • Long code lines and wide tables scroll inside their own block instead of widening the page.
  • Use Link to section to point to an H2 or H3 in the same article.

The More menu

  • Embed from link recognizes a supported video or interactive service automatically.
  • Code block inserts preformatted text and preserves spaces and line breaks.
  • Table creates a header row and the requested number of rows and columns.
  • Clear formatting removes visual formatting from the selected text without deleting it.

External content

The Video button supports YouTube, Vimeo, Rutube, VK Video and Dzen. More → Embed from link also supports approved interactive content. LiveGPSTracks links must use HTTPS, the exact domain livegpstracks.com or livegpstracks.ru without www, and a root-level PHP file whose name starts with ap, for example /apgtracks.php. Other iframe sources are removed when the article is saved.

Markdown and HTML through the API

Prefer content_markdown for ordinary articles. Fenced Markdown becomes a code block; use ## and ### for sections. Use content_html only when its structure is necessary. Publicasta accepts paragraphs, headings, emphasis, quotations, lists, links, figures and captions, images, code blocks, tables and approved embeds. Scripts, styles, event handlers, editing attributes, unsafe URLs, unknown elements and unapproved iframes are removed on write.

Compatibility and safety

Existing published HTML is not rewritten in bulk. The shared policy is applied when content is next saved through the editor, API or site tools. Check a draft after importing unusual HTML; unsupported presentation markup may be simplified while its readable text is retained.
