how do I change the CSS in order to achieve a hover-effect on each single activity-item.
So that each activity-item will get a grey background-color when hovering over it.

Very similar to each single post at Youtube.com ?

Many thanks,

.activity-list li:hover{ background: #EAEAEA; }

unfortunately, when using this code, then it is also changing the bg-color of the activity-comments.
Is there a way to keep the bg-color of the activity-comments as is ?

Many thanks,

div.activity-comments ul li:hover { background: #— !important; } replace — with what you want the color to stay as

best solution, use firebug add-on with firefox, to find ids and classes of elements n ul figure all this out..
