-### Tooltip Placement
+### Tooltip Customization
 
-Tooltip placement has a default value of `auto`, but can be fixed to a certain position if needed.
+The default tooltip can be modified by setting the relevant props configuration from [Tooltip](./Tooltip). This includes all props except for `children` and `target`.
 
 ```jsx example
-<IconButton icon="trash" label="Delete" tooltipPlacement="bottom" />
-```
-
-### Tooltip Variant
-
-The tooltip style can also be customized.

-```jsx example
-<IconButton icon="info-circle" label="More Information" tooltipVariant="info" />
+<IconButton 
+  icon="trash"
+  label="Delete" 
+  tooltipProps={{ placement: 'bottom', variant: 'info' }} 
+/>
 ```
 
 ### Offscreen Text
 
 If there are multiple icon buttons with the same label, the visible label text can be combined with `Offscreen` to provide additional context to users using assistive technology (AT).
 
 ```jsx example
-<div class="users">
-  <div>
-    User: Jason 
-    <IconButton icon="trash" label={<>Delete User <Offscreen>Jason</Offscreen></>} />
