Margin between social button custom images.

Hello nice people here.

Great plugin, if I can fix my issue I will buy a developer license of it.

This is my site: https://adsencash.com/viralsite/this-scenery-is-incredible-but-wait-until-you-see-whats-really-going-on/

As you may see the custom image button have no margin in between, so how can I have 10px margin between them??

Thanks in advance for any help ??
