The User Networking Manager part uses Cascading Style Sheets (CSS) to manage the appearance of your user networking site. CSS controls the format and layout of the site, such as the color of links, font size and types, and the spacing of tables. When you design a User Networking Manager part, you can use the Styling tab to customize the default CSS class properties of the part.
Note: The User Networking Manager part contains a large number of CSS classes. To save time and minimize rework, you manage its classes on the Styling tab rather than in Style sheets like other parts. With the Styling tab, you can adjust all the CSS classes of the User Networking Manager part in one step.
