/* BorderContainer 

Splitters and gutters separate panes within a BorderContainer. Splitters can be moved up and down (horizonal splitters) or left and right (vertical splitters), while Gutters are static. A "thumb" is the slit on a Splitter that indicates it is movable. 

Styling the BorderContainer widget consists of the following: 

.dijitBorderContainer - for border and padding of the entire border container

.dijitSplitContainer-child, .dijitBorderContainer-child - for border or child panes of the border container. By default borders are put on all children of BorderContainer.  

.dijitBorderContainer-dijitTabContainerTop,
.dijitBorderContainer-dijitTabContainerBottom,
.dijitBorderContainer-dijitTabContainerLeft,
.dijitBorderContainer-dijitTabContainerRight,
.dijitBorderContainer-dijitAccordionContainer   -for border of the border containers within TabContainer or AccordionContainer widget

.dijitBorderContainer-dijitBorderContainer - for border and padding of nested BorderContainers

Splitters and gutters:  

.dijitSplitterH, .dijitGutterH - for height, background, and border of a horizontal splitter and gutter 
.dijitSplitterH .dijitSplitterThumb - for color, height/width of the thumb on a horizontal splitter
.dijitSplitterV, .dijitGutterV - - for height, background, and border of a vertical splitter and gutter 
.dijitSplitterV .dijitSplitterThumb - for color, height/width of the thumb on a vertical splitter
.dijitSplitterHHover - for background-color of a hovered horizontal splitter
.dijitSplitterHHover .dijitSplitterThumb - for background-color of a hovered thumb on a horizontal splitter
.dijitSplitterVHover  - for background-color of a hovered vertical splitter
.dijitSplitterVHover .dijitSplitterThumb - for background-color of a hovered thumb on a vertical splitter
.dijitSplitterHActive - for background-color of an active horizontal splitter
.dijitSplitterVActive - for background-color of an active horizontal splitter
