Info box padding and background

Hello,

Great work on the upgrade to 2.0! In 1.5 I had the following code inserted to change the background of the info box on hover, as well as adding padding to make it look better. Can you please let me know how to get these effects with the new plugin?

Thank you!

.info_box:hover {
    background:#afafaf;
}
#page .info_box {
    padding:10px 0px 10px 0px;
}
