Different styles and fonts in numbered list

[Gravadi]

I am writing a tutorial on web-page design and I want to create a numbered list of steps the user needs to follow along. In between some of the steps will be text showing what the user needs to type into a text editor.



The numbered list will be in a serif font and the text between the list items will be in a mono-spaced font.

I would like to create a style for the mono-spaced text. I have tried to do this but when I apply the style, the style is also applied to the list item immediately preceding the mono-spaced text.

How can I apply a style that is not applied to the list item itself?
Thanks for your help.
