Can't see html code

Hi when I am creating a new car listing it went through successfully without any issue. However when I tried to get the html code from the page to post onto ebay, I was not able to find when can I do that. because normally I would just click on text tab in page edit to do so but, I don’t see that is an option after I created the car listing. could you help me? thanks.
