Add space between events

Hi,
You can see that I have a long list of events scheduled. I would like to improve the layout by adding space between different events – ie. after the tweet link and before the next event beneath it.
I think it looks confusing for the title of the next event to be stuck hard after the previous one, with a space following it, but not above it.
Can you please help.
Thank you.
Cheryl
