change backcolor RadWizardStep

[Fabio Cirillo]

Hi

I've the radwizard object into aspx page and i would change the backcolor RadWizardStep.I set the theme Bootstrap and I would like to change the color but did not succeed.
By using this site http://docs.telerik.com/devtools/aspnet-ajax/controls/wizard/appearance-and-styling/skin-selectors

I was able to change the color of progressbar but not the backcolor RadWizardStep.

 

How can I do?

 

Thank you bye
