Hey there,

You can add your custom CSS code for it at Backend > EasySocial > Themes > Custom CSS.

Do clear all of your caches before you see the changes.

Yes I know that I can do it in custom css. But how can I identify the classes? It‘s not working with firebug.

You can add the following custom CSS code for it.

body #es .popbox-content {

  background-color: #fff;

}



body #es.popbox--cluster a, #es.popbox--cluster a:hover {

    color: #666;

}

Do change the value of the color code that you want.

In order to identify its classes, you need to inspect it via the developer tool as shown in the video for an example. https://take.ms/ucTdc5
