Small square image works best. Will be displayed at 22×22 px in the sidebar.
Plain text: blank lines become paragraphs. Tick Advanced HTML mode to build richer pages with tables, lists, images and inline styles. Tap ? Formatting & code for what is supported.
Formatting & code in your articles
There are two ways to write an article. Leave Advanced HTML mode unticked for plain writing, or tick it to hand-build a richer page.
Plain text mode
Separate paragraphs with a blank line. The first paragraph gets a decorative drop capital automatically.
Single line breaks are joined into flowing text, so use blank lines wherever you want a new paragraph.
You can still drop in the odd inline tag such as <b>, <i> or <a href>.
Advanced HTML mode
Your markup is inserted exactly as written, so you control the whole layout: headings, paragraphs, lists, <table>, <blockquote>, <img>, links, and <div>/<span> wrappers.
Style things with an inline style="..." attribute. You can also reuse the encyclopaedia's own classes: drop-cap for a leading capital, and infobox with an inner infobox-title for a side panel.
Plain tables are styled for you; wrap them in a <div style="overflow-x:auto"> if they are wide.
Compatibility & limits
No scripts. Content is placed with innerHTML, so <script> tags and on... event attributes (like onclick) will not run. Pages are display-only.
Stay self-contained. External style sheets, web fonts and remote scripts will not load, and may be blocked when the file is opened offline.
Images: use a full https:// address (needs internet) or, to keep it working offline, a data: URI. Very large images may exceed the save limit.
Iframes and embeds (videos, maps) often will not display offline; prefer a link or a static image.
Use the site's theme colours where you can: var(--gold), var(--ink), var(--paper-mid), var(--border) — so your page matches light and dark modes.
If something looks wrong, untick HTML mode to fall back to plain paragraphs.
