Question

How could I go about changing color on hover and at the same time dim the rest to a different color and/or opacity.

A simple three list items enclosed within it’s unordered list.

These list items change color on hover.

Code:

.right-side .headlines li a,.right-side .headlines li{font-size:36px;color:#999}
.right-side .headlines li a:hover{color:#0976ca}

<ul class="headlines">
    <li>
        <a href="#">Headline 1</a>
    </li>
    <li>
        <a href="#">Headline 2</a>
    </li>
    <li>
        <a href="#">Headline 3</a>
    </li>           
</ul>

Thanks Guys
