How to write ruby ​​code in css file

I have a rails application in which I need a css file so that its property can be changed using ruby ​​code. ex. background_color: <% = ruby ​​code that returns the background color%>

Thus, the user can set his css property and will be applicable only to this user as a topic.

Thank!
