[Theme: Zerif Lite] How to space Youtube videos in Ribbon

Dear Person-In-Charge,

I had followed the instructions from here on how to embed a video on front page and successfully put 3 videos together:

However, the videos at my site, kakibola.com are joined together (see pic attached):

Can someone provide instructions on how to put a tiny spacing between the videos? I’m not a coder or programmer and started using WordPress only last year.

Regards,
Kit
