## Usage
This component provides accessible syntax highlighting for `bash`, `diff`, Javascript, JSON, YAML/YML, HTML, CSS and Sass/SCSS.
_If there are any languages you would like to highlight that we don't currently support, please open an issue and we will provide it._
o-syntax-highlight uses the following colours, on a `grey-5` background (`#f2f2f2`). It is compliant with the contrast for [WCAG AA](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html). In order to meet the criteria for AAA at 14px+, the colours would be far too dark to distinguish syntax highlighting effectively.

### Markup
o-syntax-highlight works with a single class. As long as this class is present in a wrapper that holds the code you wish to highlight, it will tokenise and colorise the syntax according to your preference. The semantically correct way of declaring a code block is to place a `<code>` inside a `<pre>`. That is what o-syntax-highlight looks for when it is tokenising the code block.
