# changing footnote box color in beamer?

How can i change footnote box color in beamer? I can set the text color and other properties but unable to change the color of the box. Meanwhile, how can i adjust the length of the footnote?

You can use Beamer command \setbeamercolor{}. In this case use \setbeamercolor{footlinecolor}{fg=<color1>, bg=<color2>}. You might also want to change the \setbeamercolor{footnote}{fg=<color>, bg=<color>} and \setbeamercolor{footnote mark}{fg=<color>, bg=<color>}. As for the width have a look here: How do I adjust the width of Beamer's footnote "area"?
