The following example shows how to use the imAnimTabber with the attribute option set to 'fade'. I also set the mode to 'manual' because I created the tabs myself rather than have the plugin do it for me. Also, notice that I do not need to set the 'tab_container' option because I have used the 'class_name' option within the 'tabs' option. The 'class_name' option can be set when using the 'height', 'width', and 'fade' attribute options (in manual mode). I also don't need the 'caption' option when in manual mode. Remeber, when using 'width' or 'fade' attribute, you must set the default content that will be displayed ("select": true). View the source for this page to view the CSS styling.
