Lowering the visual impact of some of your wiki's elements to give more precedence to the others can be done in two ways.
Firstly, you can simply adjust the visual impact of the elements in your design using the focus-drawing techniques that we discussed. This will place the more important elements at a higher level of your wiki design's visual hierarchy.
Note
For major changes in the focus of elements on your wiki, this probably isn't suitable. As a result, you may want to reconsider your wiki's overall layout and design.
Secondly, you can use some other ideas for getting the attention of your wiki's visitors. These are as follows:
lower contrast, both within the element, and in relation to the other elements
smaller sizes, without making the element's content unreadable; it may be possible to reduce its size, and, thus, the impact
less indentation and padding
