smalldocs 0.2.0

A site can now use a theme from a git repository. smalldocs add org/repo copies the theme into the folder _extensions/ of the project, and theme: <name> uses it. The same folder can hold a theme for Quarto, so one repository serves both tools. smalldocs themes lists the themes and where each came from. See Themes.

smalldocs-tufte is the first such theme. It gives a site the look of Tufte CSS, in a light mode and a dark mode. Its demo shows it.

A page can now put content in the margin, as Quarto does:

• reference-location: margin puts each footnote beside the paragraph that cites it.
• A div with the class .column-margin, or a span with the class .aside, goes in the margin.
• fig-cap-location: margin puts the caption of a figure beside it.
• The classes .column-page, .column-screen and .column-body-outset make content wider than the text.

See The margin and wide content.

Other changes:

• A site with a light theme and a dark theme starts in the mode that the browser prefers. The page loads the right theme before it shows anything, so it does not flash the other theme first.
• A theme file named x.min.css keeps its name in the site.
• A theme can set the size of the text with the variable --sd-root-font-size.
• In a _quarto.yml, format: <name>-html is read as html.
