缩放

Question

我有以下HTML。问题是当我放大或缩小时，我无法使id =“ladder”的div与其id =“grid”的父div具有相同的位置。这是代码snakes and Ladders

var gameBoard = {
  createBoard: function(dimension, mount) {
    var mount = document.querySelector(mount);
    if (!dimension || isNaN(dimension) || !parseInt(dimension, 10)) {
      return false;
    } else {
      dimension = typeof dimension === 'string' ? parseInt(dimension, 10) : dimension;
      var table = document.createElement('table'),
        row = document.createElement('tr'),
        cell = document.createElement('td'),
        rowClone,
        cellClone;
      var output;
      for (var r = 0; r < dimension; r++) {
        rowClone = row.cloneNode(true);
        table.appendChild(rowClone);
        for (var c = 0; c < dimension; c++) {
          cellClone = cell.cloneNode(true);
          rowClone.appendChild(cellClone);
        }
      }
      mount.appendChild(table);
      output = gameBoard.enumerateBoard(table);
    }
    return output;
  },
  enumerateBoard: function(board) {
    var rows = board.getElementsByTagName('tr'),
      text = document.createTextNode(''),
      rowCounter = 1,
      size = rows.length,
      cells,
      cellsLength,
      cellNumber,
      odd = false,
      control = 0;
    for (var r = size - 1; r >= 0; r--) {
      cells = rows[r].getElementsByTagName('td');
      cellsLength = cells.length;
      rows[r].className = r % 2 == 0 ? 'even' : 'odd';
      odd = ++control % 2 == 0 ? true : false;
      size = rows.length;
      for (var i = 0; i < cellsLength; i++) {
        if (odd == true) {
          cellNumber = --size + rowCounter - i;
        } else {
          cellNumber = rowCounter;
        }
        cells[i].className = i % 2 == 0 ? 'even' : 'odd';
        cells[i].id = cellNumber;
        cells[i].appendChild(text.cloneNode());
        cells[i].firstChild.nodeValue = cellNumber;
        rowCounter++;
      }
    }
    var lastRow = rows[0].getElementsByTagName('td');
    lastRow[0].id = '100';
    var firstRow = rows[9].getElementsByTagName('td');
    firstRow[0].id = '1';
    return gameBoard;
  }
};
gameBoard.createBoard(10, "#grid");
