title: Good file type for displaying text and images in a UIWebView
body: <p>A UIWebView can be used to display a variety of file types (ex: a.xls .key.zip .numbers.zip .pages.zip .pdf .ppt .doc .rtf .rtfd.zip .key .numbers and .pages).</p>
  
  <p>I am working on a "How to use this application" part of my app and would like to find a good file type (stored locally) for displaying some text and images in a UIWebView.</p>
  
  <p>The problem is lack of control over the final result. For example, text size seems to have no effect in either a .rtf or .doc file. I want to have a reasonable amount of control over the text and image properties. I could use a pdf, but I don't like the way the pdf's are framed, making everything that much smaller on the screen.</p>
  
  <p>Does anyone have any experience displaying various file types in a UIWebView. What file type enables good creative control over the final result?</p>
