 ## Default renderer rules
 Rules on how to translate markdown content to HTML elements are stored in `renderer.rules`:
 
-```
+```js
 const MarkdownIt = require('markdown-it');
 const md = new MarkdownIt();
 
 console.log(Object.keys(md.renderer.rules))
 ```
 Output:

 Looking at [the API documention for Token objects](https://markdown-it.github.io/markdown-it/#Token.attrJoin) we find the `attrJoin` method. This method allows us to join an existing attributes value with a new value or create the attribute if it doens't exist yet.

 Let's imagine we are using CSS pseudo classes such as `:before` and `:after` to style our list because using `list-style-type` doesn't provide the bullet types we want and `list-style-image` isn't flexible enough to position itself properly across all major browsers.
 
 To keep a proper line wrapping in our list we have set all elements in our `li` to display as a block (`li * {display: block;}`). This works for our pseudo classes and other `HTMLElements`. However, it does not work for `TextNodes`. So having this output will produce weird line indents:
