Easy Facebook Likebox creating CSS issues with other plugins

I would like to use the Facebook Feed but the css from it breaks several other plugins.

This includes “Cookie Consent” and “Popup Maker”.

The problem seems related to this css entry:

.responsive, .responsive span, .responsive span iframe[style], .responsive span img {
    width: 100% !important;
}

Do you have any quick fix for this and can you look into this problem?

thank you
