Change style of Post Tags

Hi! I've been trying to change the style of my post tags for the last few hours, but just can't figure it out. So far I've learned that if I add this to the custom CSS...:

.entry-meta .in-tag {
color: #ffffff;
background-color: #0088cc;
padding: 5px;
}

...I get pretty close to getting what I want. Ofc it's far from correct, but at least I've been able to manipulate the part of the site that I want to. What I specifically want, is for my post tags (not the text saying "tagged") to have a background color of #0088cc, a padding of 5px (preferable with rounded corners) and the text changed to white. My goal is to make the tags Pop, so that people notice them more. Now, how do I do this? Thanks in advance.
