I need help fixing CSS issues with an embedded widget I placed in a text widget

I obtained the javascript for a widget from http://www.oil-price.net and inserted it into the home 1 widget on my client's page (www.smartline.us/eneins/) and when I did, the site's CSS overrode the CSS that was included with the javascript. Now the widget is not displaying correctly. Correct display can be seen at http://oil-price.net/dashboard.php?lang=en.

I added a DIV around the widget in hopes that I could reset the CSS for just that widget but I haven't been able to figure this out. I need help. :slight_frown:

Thank you so much for any help you can give.
