ASP.net Allowing cuss designer access to web app

Hi
I have built an ASP.net web application that I need design help with. I don't want to share my entire project with a cuss designer but rather give him just enough access to see my mark up code.
I have never done this before so am looking for advice on the best way to do this.
Is there a way in Visual Studio 2017 to collaborate in this way?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You cold publish it to a free hosting service such as azure and have them look at the mark up from the browser. Not ideal but should work.

I would generally create a prototype or dummy project and let the customer access it - I keep the core code within my private repositories where I have total control over who gets to see what (Including my team members)
