Host plain html web page in APEX 4.0

I have a html/javascript web page that I need to run unmodified on APEX 4.0, I can't seem to figure out to achieve this. In older version of APEX you could put header and body html in page attributes, I can't see something similar in 4.0

Appreciate your inputs, I am sure I am missing out somethin开发者_JS百科g very stupid.

EDIT: I don't see the page attributes, I just see this:

Apex 4.0 still has page HTML Header and Body attributes.

You can also put pure HTML in an HTML region source.

However, it also has a new type of application called a Websheet and it appears that you have created one of these, either intentionally or by accident.
