Hi Lois!\
he scriptlet and ~ here is specific to aspx [file](https://www.mindstick.com/articles/59/encrypting-and-decrypting-files-using-c-sharp) and could not be used in css.\
Change\
background-image: url('<%=Page.ResolveUrl("~/Themes/Red/Images/Contestant/1.jpg)%>';)To\
background-image: url('/Themes/Red/Images/Contestant/1.jpg')Assuming the Themes folder is at root your your site.
