Different free places in the Feature Columns

Hello,
1. how can I make the distance between the Feature Column Images and the Feature Column Headings smaller?
2. how can I make the distance between the Feature Column Descriptions and the Read more button smaller?
Thank you!

Paste this code in Custom CSS

Code:

margin-top:5px;
}
