Timeline Edits

Hey guys,

Few things regarding the timeline:
1. Can we reduce some of the padding between the different dates?
2. The bullets aren’t showing up.
3. The navigation arrows aren’t changing colors, I’m using the code below:

.main_color .av-timeline-nav a span {
background-color: #333;
}

I’ve cleared the cache of the site and my browsers but nothing in changing. The link is below, thanks!
