Had another look, and it may be that the article is created using the wysiwyg editor...
This adds styling to the code ( < p> elements ) breaking the layout.
Note: if you want to write pure HTML into a HTML article you should not use the wysiwyg editor, but maintain it in the Source view...
try this: go into the article, make sure that the wysiwyg editor is switched off: (View Source, Ctrl+Shift+S)
The entire HTML code should be pasted in there. You can leave all the < head> stuff in there too...
