**Vision**: Provide the lowest common denominator between HTML/CSS/JS and Gemini.

# HTML spec
2021-01-26 22:29:24 +00:00
2021-01-29 18:51:53 +00:00
## `<head>`
2021-01-28 06:16:46 +00:00
2021-01-29 18:51:53 +00:00
The generated HTML document must have a `<head>` tag with _at minimum_ the following:
```html
< head >
< meta charset = "utf-8" >
< meta language = "en" > <!-- set this accordingly! -->
< meta name = "viewport" content = "width=device-width,initial-scale=1" >
< / head >
2021-01-29 06:48:39 +00:00
```
2021-01-26 01:14:34 +00:00
2021-01-29 18:51:53 +00:00
You might want to also include these (or whatever else):
2021-01-26 22:29:24 +00:00
2021-01-29 18:51:53 +00:00
```html
< title > < / title >
< link rel = "canonical" href = "gemini://" >
< meta name = "description" content = "" >
```
2021-01-29 07:03:10 +00:00
2021-01-29 18:51:53 +00:00
## `<body>`
2021-01-29 07:03:10 +00:00
2021-01-29 18:51:53 +00:00
The converted Gemini document should be placed inside the `<body>` . Due to the ambiguity of HTML several translations from Gemini exist in the wild. I propose the following standard:
2021-01-26 01:14:34 +00:00
2021-01-29 07:03:10 +00:00
```
2021-01-29 18:51:53 +00:00
< p >
< a > ↔ =>
< pre > ↔ ```
< h [ 1-3 ] > ↔ #[##]
< li > ↔ *
< blockquote > ↔ >
2021-01-29 07:03:10 +00:00
```
2021-01-29 18:51:53 +00:00
The `<a>` for a link should be presented un-wrapped without any parent elements. Many implementations use `<div>` or `<p>` to enforce "block" styling as opposed to the default "inline" which renders the link next to the previous block instead of below it. But the nested markup adds an unnecessary layer of indirection in semantics. The best way to handle this is to include `<style>a {display: block;}</style>` in the `<head>` .
2021-01-29 07:03:10 +00:00
2021-01-29 18:51:53 +00:00
Empty lines should simply be represented as `<p><br></p>` this sets up `contenteditable=true` to add content to the line compared to just `<br>` .
2021-01-29 07:03:10 +00:00
2021-01-29 18:51:53 +00:00
Take care to render `<pre>` blocks with their original formatting, DO NOT indent the generated
HTML for these tags.

2021-01-29 18:51:53 +00:00
Much like the lines of a `<pre>` , the lines of `<li>list items</li>` need to be wrapped in `<ul>` , indention here is not significant. Sometimes a list item is empty: `<li><br></li>` .

### Optional: inline media
2021-01-26 01:14:34 +00:00
2021-01-29 18:51:53 +00:00
If a link is consumable by `<img>` , `<audio>` or `<video>` you may insert the respective tag inline instead of an `<a>` . Images and video should be styled to have `max-width: 100%;` so they don't overflow the body. It's a good idea to also include the "controls" attribute. `<audio>` tags require `display: block;` just like `<a>` .
### Basic `<style>`
Without any CSS the browser renders all of this just a lil wonky. At bare minimum I recommend including the following in the `<head>` of all your generated .html files.
2021-01-26 01:14:34 +00:00
2021-01-29 06:48:39 +00:00
```html
2021-01-29 18:51:53 +00:00
< style > p , a , pre , h1 , h2 , h3 , ul , blockquote , img , audio , video { display : block ; max-width : 100 % ; margin : 0 ; padding : 0 ; overflow-wrap : anywhere ; } < / style >
2021-01-26 01:14:34 +00:00
```

## gmi-web(1)
2021-01-29 18:51:53 +00:00
A reference implementation of what has been discussed above!
2021-01-29 06:48:39 +00:00
*You will need*:
- [node(1) w/ npm(1) ](https://nodejs.org/en/ )
```sh
npm install -g git+https://codeberg.org/talon/gmi-web.git
2021-01-29 19:55:24 +00:00
man gmi-web
2021-01-29 06:48:39 +00:00
```
2021-01-29 22:36:30 +00:00
Render .html for all the .gmi files in the current directory
2021-01-29 22:49:09 +00:00
```sh
2021-01-29 23:27:39 +00:00
gmi-web --lang en $(find . -name *.gmi)
2021-01-28 17:56:02 +00:00
```
2021-01-29 23:27:39 +00:00
### gmi.css
2021-01-29 18:51:53 +00:00
Optimized for readability, predictability, mobile-friendliness and
ships with a handful of customizable variables. See `man 5 gmi.css` .
2021-01-29 22:49:09 +00:00
The `--foreground` and `--background` variables will be inverted when
`prefers-color-scheme` is "dark" which is a system-level preference on
2021-01-29 18:51:53 +00:00
devices.
2021-01-29 22:36:30 +00:00
Any of the variables can be customized by adding a style to the `<html>` element.
2021-01-29 18:51:53 +00:00
```html
< html style = "--foreground:#555555; --background:#9EEBCF;" >
```
2021-01-29 19:55:24 +00:00
When using `gmi-web(1)` they can be customized by providing _OPTIONS_ of the same name as the CSS variable.
```sh
2021-01-29 23:27:39 +00:00
gmi-web --lang en --foreground "#FFFFF" --background "#00000" *.gmi
2021-01-29 19:55:24 +00:00
```

]
window.gmi.lines[0].type = "H3"
