# Thanks for trying out JSS

You can add a new rule (or extend an existing rule) as follows:

`jss.set('code', { color: teal; });`

You can retrieve the rules for a specific CSS selector as follows:

`jss.getAll('code');`

This will return an object:

`{"color":"teal"}`

You can also completely remove an existing rule using:

`jss.remove('code');`

## Here's a live example:

Choose your colour:

Teal

Choose your font style:
