You can draw focus to an element on your wiki by using one or more of the following techniques:
Suggestion of movement, including the use of arrows
Color contrast
Diagonal lines
Indentation
Padding
Size
Ordering
Depth, and the impression of 3D
Our eyes are designed to respond to movement. Anything that appears to be moving (or actually is moving), will tend to draw your visitors' focus.
Note
Movement and Advertisements:
Beware of making things that look like animated banner adverts, as your visitors may associate these with advertisements and ignore them. Refer to: http://www.useit.com/alertbox/9709a.html.
For example, by applying a motion blur to each of the sponsors' logos, we can attract our visitors' attention to them:
On the other hand, this motion blur makes the logos less legible for our visitors. So we should clearly exercise caution here.
