I am considering creating a tic-tac-toe game using jQuery and PHP. I would like to customize the design of the game board, which is represented by an HTML table, by applying CSS styling. However, I am struggling to find CSS properties that would allow me to add borders selectively to certain cells. Are there specific CSS properties that can achieve this, or should I explore alternative methods?
The structure of the HTML code for the game board:
<div id="board">
<table>
<tr id="row1">
<td class="square"></td>
<td class="square"></td>
<td class="square"></td>
</tr>
<tr id="row2">
<td class="square"></td>
<td class="square"></td>
<td class="square"></td>
</tr>
<tr id="row3">
<td class="square"></td>
<td class="square"></td>
<td class="square"></td>
</tr>
</table>
</div>
