Clojurians Log v2

Hi. I am trying to convert a garden.unit into a string, to be used on a cljss or inline styles. I am not using garden for generating stylesheets, just for units and colors functions. Doing (css (u/px 24)) did not work, it says Can't create empty: garden.types.CSSUnit. Any ideas how I can solve this? Any other library that plays better with cljss and inline styles that allows for color and units tools? Thank you!
