On my 3D game comparison's honorable mentions page, I currently use PHP to include a text file (the 3-game comparison at the bottom) with minimal HTML code (just for links, indentation, text formatting, etc--but no page/text colors are specified, thus defaulting to the web browser's colors). Now, on the page's black background, the PHP included file inherits the mentions.html's background/text colors. However, if I use an iframe to embed the file, the text color remains black instead of changing to the lighter blue-grey. Why? I've tried setting the iframe's style to a different background color, but I can't get the embedded file's text color to change (unless I edit the page itself, which I don't want to do). Any ideas?
