# Rules
267+
268+
Rules are used to specify how you want certain elements to be displayed. The existing implementation is [here](https://github.com/iamacup/react-native-markdown-display/blob/master/src/lib/renderRules.js)
269+

The list of rules that can be overwritten is:

# Style
323+
324+
Styles are used to override how certain rules are styled. The existing implementation is [here](https://github.com/iamacup/react-native-markdown-display/blob/master/src/lib/styles.js)
325+
326+
The list of styles that can be overwritten is:

329+

**NOTE:** There is no merge of the style properties, if you specify a style property, it will completely overwrite existing styles for that property.
