Currently, I'm developing a project in Angular2 utilizing ngSemantic. I have implemented semantic's popup (sm-popup) in certain areas, but I've noticed that there is always a white margin surrounding the border by default. I would like the entire popup to be one consistent grey color, which is why I am looking to remove the white margin (or padding, depending on perspective). Despite searching for two days, I have been unable to find where I can configure this setting. Has anyone else faced a similar issue?
