```
public Board()
```
    Creates an empty board.
    Use addRow(Component...) to add content to the board.
- Method Detail
  - addRow
```
public Row addRow(Component... components)
```
    Creates a new row and adds the given components to the row.
    All the added components have cols set to 1, i.e. use one slot in the row. The number of slots in the row is the number of added components.
    
    Parameters:
    
    components - components to add, no more than 4
    
    Returns:
    
    a row instance which can be used for further configuration
    
    Throws:
    
    IllegalArgumentException - if there are more than 4 components
  - removeRow
```
public void removeRow(Row row)
```
    Removes the given row from the board.
    
    Parameters:
    
    row - the row to be removed
  - redraw
```
public void redraw()
```
    Forces the board to be redrawn.
    This method typically only needs to be called if you change CSS (through a variable or otherwise) which affects the size of the board or the breakpoints used. Otherwise, the component will be redrawn automatically when needed.
