Upfront Responsive Logo


I’m having trouble setting the size of the sites logo when the page is responsive. The default shrinks the logo to about 10% of its original size. I can’t find the CSS that controls this but wanted to target it with something like

@media all and (max-width: 250px) {
.upfront-image-container {
max-width: 100% !important;
left: 0 !important;
bottom: 0 !important;

Thanks for any help
