Where can I find the html code?
Html for what, do you want to make/edit a theme?
If so,
ACP > Templates & Style > Templates **or** Themes (depends on what you're editing) > *desired theme*
More specific?
If you mean for your site and you want to edit the html, go to the Admin CP -> Themes and Templates -> Templates (on sidebar) -> Theme you want to edit -> Click on the Template set that falls under the catagory you want to edit -> The Template
Then you should edit it easily.
