Themes

Good afternoon, you will see, I use Moodle 2.0.3 + with the theme leatherboud. Everything goes well but I tried to resize the iframe in which show the pdfs and other resources but no way. I've changed in the Extensions panel management / business modules / files and nothing. Looking at the code, I see that the object which is embedded the pdf appears with a style in line with the width and height defined style = "width: 810px; height: 400px; ". Upon seeing this, it is clear that even if I resize the panel management, it does not, use the line style. I've looked at the theme, in which parent themes inherited (canvas and base) and nothing! Any solution?
