I mentioned in an earlier post that the in post ads in the dark view have a css bug where the top bar is white instead of the dark theme divider.
I was using developer console to find the css for this so I could change it, I was able to find it but when I try and overwrite it in the Custom CSS, it does not seem to take the edit and I have cleared my cache...
Here is the CSS I am trying:
.Flagrow-Ads-fake-poststream-item {
border-top: 1px solid #262627;
}
