[Theme: Corlate] Problem with Nav Buttons CSS

Hi All,

We’re creating a mockup for a new theme based on Corlate

We’ve a strange css misconficuration on the navbar > li. When clicking in one of the links the button background slowly disappear (on ie, chrome and firefox, not in safari). Tried few times to inspect the various statuses of the buttons (active, hover, focus,) but nothing come up.

We’d like to change the #fff with the original black color. I cant understand if is from css or js

Someone can help?

Thanks
