What does "Show the structure of your code" mean?

Question

Freelance

There is work - to make up a site.
The customer tells me to show her the structure of my code.
What to show her. Just the source code of the page I made or something else?

Answer 1

Just drop the source

Answer 2

Isn't it easier to ask "her" what she means? The worst thing that can happen is a lack of understanding and trust. How are you going to work then?
The original html is viewed and edited in any browser. But it's about how you type. Portfolio type.
