- <p>
- The <code>html</code> and <code>markdown</code> rendering is limited: bolds may be embedded in italics, italics may be embedded in bolds, and mono-spaced may be embedded in bold or italic, but will not be altered by those font mods, nor will embedded bolds or italics be handled.
- The only entities that will be observed in html are <code>&lt;</code> and <code>&amp;</code> and in <code>markdown</code> a backslash will escape the following character (including a backslash) from special processing.
- Any font mod that is started in a label line will be implicitly terminated at the end of that line.
- While this interpretation may not exactly match <i>official</i> rendering standards, it is a consistent compromise for drawing multifont strings in the non-multifont html canvas element underlying vis.
- </p>
-
- <p>This implies that four additional sets of font properties will be recognized in label processing.</p>
- <p class="indented"><code>font.bold</code> designates the font used for rendering bold font mods.
- <br/><code>font.ital</code> designates the font used for rendering italic font mods.
- <br/><code>font.boldital</code> designates the font used for rendering bold-<b><i>and</i></b>-italic font mods.
- <br/><code>font.mono</code> designates the font used for rendering monospaced font mods.</p>
- <p>Any font mod without a matching font will be rendered using the normal <code>font</code> (or default) value.</p>
-
- <p>The <code>font.multi</code> and extended font settings may be set in the network's <code>nodes</code> or <code>edges</code> properties, or on individual nodes and edges.
- Node and edge label fonts are separate.</p>
