XF 1.4 How to remove gradient from "Latest" and "Replies" blocks

[xelA]

On the Node List (forum list), there is gradient for "Latest" block. Then there on the Thread List, there is gradient for "Replies."

How do I go about removing those gradients via AdminCP, or if that doesn't work, via EXTRA.css?

Thanks in advance.

Add to EXTRA.css:

.node .nodeLastPost
{
    background-image: none !important;
}

.discussionListItem .posterAvatar, .discussionListItem .stats
{
    background-image: none !important;
}
