The converted Gemini document should exist inside the <body>. Consider if sharing the page with other HTML to put the core document inside <main>. Each Gemini line-type may be translated using the following guide:
<p> ↔
<a> ↔ =>
<pre> ↔ ```
<h[1-3]> ↔ #[##]
<li> ↔ *
<blockquote> ↔ >
<li> must be wrapped in <ul>. Take care to render <pre> blocks with their original formatting, do not indent the generated HTML for these tags.
<a> tags are categorized as inline which CSS Normal Flow presents vertically—Gemini only deals with horizontally flowing content, this can be addressed by using display: block; at the CSS level.
optional: inline media
If a URL is consumable by <img>, <audio> or <video> you may insert the respective tag inline, instead of an <a>. It's a good idea to also include the controls property.
These are categorized as inline just like <a> and will need display: block; styling. Images and video should also have max-width: 100%; so they don't overflow the body.
<html> and <head>
When producing a complete and valid HTML5 document the first declaration is the required <!DOCTYPE html>. At the root of a document is the <html> tag which should have a lang attribute declaring the overall language of the page as well as dir="rtl" if necessary.
A <head> tag with at least the following must be included:
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title></title>
These may also be nice to have:
<meta name="author" content="" />
<meta name="description" content="" />
<link rel="canonical" href="gemini://" />
<meta name="color-scheme" content="dark light" />
gmi.css
gmi.css is a maximally miniminal stylesheet that overrides the default CSS Normal Flow to render content horizontally in a Gemini way. gmi-web.css extends upon that slightly with font and color options. The default values are optimized for readability and mobile-friendliness and may be customized by adding a style property to <html>.
<head>
<!-- assuming you wanna host a copy and link to it... -->
<link rel="stylesheet" type="text/css" href="gmi-web.css" />
<meta name="color-scheme" content="dark light" />
<!-- ... -->
</head>
<html style="--foreground:#555555; --background:#9EEBCF;">
<!-- ... -->
</html>
The --foreground and --background variables will be inverted when
prefers-color-scheme is "dark".
gmi-web(1)
A command-line utility that pulls all of the above together into a unix-like API for creating HTML from Gemini documents.
npm install --global gmi-web-cli && gmi-web --help
config
A JSON file can be passed to --config for conveniently applying any option without using the command-line flag. For example a web.json file with the following contents...
{
"html": "en",
"description": true,
"foreground": "#137752",
"background": "#F4F4F4"
}
...can be used like so:
gmi-web --config web.json $(find ~/gmi/dst -name '*.gmi')
css
gmi-web ships with gmi.css and gmi-web.css but it is possible to use your own set of completely custom CSS rules and variables by pointing to a file containing them!
gmi-web --body --css custom.css < doc.gmi
gmi-web auto-detects the need for the <meta> color-schemes and allows for using --inline to insert the declarations as style properties on their respective blocks. Variables defined in :root will be picked up and made available for configuration just like gmi-web.css.
