Please no generic links to oxwall theme tutorials i've been through it all but cannot find a html file.
ow_themes/yourtheme/masterpages you will have a dndindex and a general html page
also for other pages refer to the plugins html pages which are located as such
ow_plugins/the plugin name/views/controllers/
there are also some for the base of the software
ow_system_plugins/base/views/controllers
there are other files in other places but they are typically used for widgets and components.
hope that helps
And anytime you copy from a webpage, always!!!!!! past it to notepad or one of the others i mentioned before you paste it in your code file.
Hope that helps
