Views

I want to add some css style that I calculate in my ruby code within a haml template.

I understand that I should use the :css filter to add a style tag for my css like this:

%head
  - my_color = "#0000ff"
  :css
    .my-class { 
      / how can I set my_color here:
      background-color: red; 
    }

But how can I use my_color inside the filter?

Edit: To be clear, I am looking for a <style> tag, not inline css on an element.

You can interpolate the variable with #{my_color}:

- my_color = "#0000ff"
:css
 .my-class {
   background-color: #{my_color};
 }
