The below is about as specific as I could identify the class to the .sponsor_logo be but even with all of this in Chrome it was failing to render the display: inline but instead showing it being overruled (although I can't find the line in the CSS that's overruling it off-hand).
html body div.container_12 div.prefix_1.grid_10.suffix_1.footer ul.sponsors div.row li#stillalive.sponsor div.sponsor_logo {
display: inline;
}Simply changing the existing styles to read as follows fixes it:
.footer ul.sponsors li .sponsor_logo {
...
display: inline !important;
...
}For the record, I'm really not a fan of adding !important to my styles, but unless someone else can identify the offending CSS style this is the best I can come up with after playing for 30 or so minutes and shouldn't cause any negative ramifications since it's specifically limited to .sponsor_logo classes.
