TocGroup style class controls the style of table of contents.

It is specialized into the TocTitle sub class to manage title style, and into cascading sub classes TocLevel1 to TocLevel7 and TocLevelN, to handle styles of all subtitle levels.

It also includes TocImagesGroup and TocImage classes to handle respectively the table of contents set of thumbnails, and each thumbnail.

Example :

 Class TocGroup
font-family:arial;

 Class TocTitle
text_align:center;
font-size:20pt;

 Class TocLevel1
margin-left:20pt;

 Class TocLevel2
margin-left:20pt;

 Class TocLevel3
margin-left:20pt;
font-size:0.8em;

 Class TocLevel4
margin-left:20pt;
