Lightbox how to get the original facebook look

Hello @mesmaquel.

I am suggesting some custom CSS for your queries. Please, find the snippet below:

1 To change text color for Like and Comment link:

.rtmedia-actions-before-comments .rtmedia-like span, .rtmedia-actions-before-comments .rtmedia-comment-link { color:green; }

2 To change the background color for You like this text:

.rtmedia-like-info {
    background: grey;
}

3 To change the background color for the button Comment:

body #buddypress input[type=submit], #buddypress input[type=submit]:hover{
    background: #BE1E2D;
}

I hope this will help you.

Thanks.
