Sets the border size for all elements in the grid.

Parameters

• num (number): The size of the borders. ####Example

board.elements().size(2);

getPosition(item: HTMLDivElement): Position

Gets the position of a specific item in the grid.

Parameters

• item (HTMLDivElement): The item whose position is to be determined.

Returns

• Position: The position of the item within the grid with x and y.

Example Usage

const container = document.getElementById('grid-container');
const options = { width: 5, height: 5 };
const board = new BoardMaker(container, options);

board.init();
board.on('init', (context) => console.log('Grid initialized!', context));
board.emit('init', container);
const elements = board.getElements();
console.log(elements);
