TaskFieldsGroup style class has 3 sub classes : TaskFieldsSubtitle manages associated subtitle style, TaskFieldName manages custom fields names style, and TaskField manages custom fields values style.

Example :

 Class TaskFieldsGroup
font-size:0.8em;
font-family:arial;
margin-left:30pt;
margin-right:30pt;
color:white;
float:left;
background-color:RGB(74, 128, 193);

 Class TaskFieldsSubtitle
font-weight:800;

 Class TaskFieldName
font-style:italic;

 Class TaskField
font-weight:800;
background-color:RGB(123, 182, 225);

In such an example, custom fields are stored in a floating table with a blue background, written in white with arial font, with italic letters for field names and bold characters for field values.
