slider font size; remove extra space

I accidentally deleted all of my custom CSS; I've managed to find most of it in the support forums, but I need help with two things.

First, how do I change the slider description font size and color?

Second, how do I remove excess space between the feature image and the feature heading?

Thanks!

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

1)

Code:

.flex-caption p {
color: your color value;
font-size: 13px;
}

2)

Code:

.feature-content h1 {
margin-top: 20px;
}
