# remark-attr

This plugin add support of custom attributes to Markdown syntax.

**This is an alpha not ready to be used in production.**

For the moment, it only support image and link.

It aimed to support any other elements of the markdown syntax.

Also for security reasons, this plugin should use [html-element-attributes](https://github.com/wooorm/html-element-attributes).  
The use of JavaScript attributes (onload for example) must not be allowed by default.

## Default Syntax


Images : 
```markdown
![alt](img){attrs} / ![alt](img){ height=50 }
```

Links   :
```markdown
[Hot babe with computer](https://rms.sexy){rel="external"}
```

## rehype

This plugin is compatible with [rehype][rehype].
Actually, it wouldn't really do much good otherwise.
At the moment it aims is to be used with remark-rehype only.

```md
[Hot babe with computer](https://rms.sexy){rel="external"}
```

gives:


```html
<a href="https://rms.sexy" rel="external">Hot babe with computer</a>
```

## Installation

```bash
npm install remark-attr
```

```

### Usage:
