【问题描述】：

我编写了一个简单的井字游戏。当桌子出现时，一切都被压扁了。有没有办法让桌子空着但不被压扁？另外，我正在使用 NotePad++，当我尝试在 FireFox 中运行我的程序时，这些功能不起作用。我不知道为什么，有人知道吗？我可以让它在 Chrome 中工作，但它需要能够在 FireFox 中工作。这是我的程序：

<html>
<head>
    <style>
        .Square{
        width:60px;
        height 60px;
        text-align:center;
        font-size: 18pt;
        font-weight: bold;
        font-family: Verdana;
        }
    </style>

        <script>
            function startGame()
                {
                    for (var i = 1; i<= 9; i = i + 1)
                    {
                        clearBox(i);
                    }

                document.turn = "X";
                if (Math.random()< 0.5)
                {
                    document.turn = "O";
                }
                document.winner = null;
                setMessage(document.turn + " gets to start.");
            }

            function setMessage(msg)
            {
            document.getElementById("message").innerText = msg;
            }

            function nextMove(square)
            {
                if (document.winner != null)
                {
                    setMessage(document.winner + " Already Wone the Game!");
                }
                else if (square.innerText == "")
                {
                    square.innerText = document.turn;
                    switchTurn();
                }
                else
                {
                    setMessage("That Square is Already Used.")
                }
            }

            function switchTurn()
            {
                if(checkForWinner(document.turn))
                {
                    setMessage("Contratulations " + document.turn + "! You Win!");
                    document.winner = document.turn;
                }
                    else if (document.turn == "X")
                        {
                            document.turn ="O";
                            setMessage("It's " + document.turn + "'s turn!");
                        }
                    else
                    {
                        document.turn ="X";
                        setMessage("It's " + document.turn + "'s turn!");
                    }
            }

            function checkForWinner(move)
            {
                var result = false;
                if(checkRow(1,2,3, move) ||

                }
                return result;
            }

            {
                return document.getElementById("s" + number).innerText;
            }

【解决方案1】：

您在height: 60px; 中的height 之后忘记了:

最初，我建议添加td {height: 40px;}，但是......只需添加: 就可以了。

<style>

    td {height: 40px;} //nevermind, you don't need this

    .Square{
        width:60px;
        height: 60px; //I JUST REALIZED YOU FORGOT A : 
        text-align:center;
        font-size: 18pt;
        font-weight: bold;
        font-family: Verdana;    }

</style>

【讨论】：

@retrogirl19 我刚刚意识到 - 你实际上只是忘记了: after 身高。你不需要整个td 命令>.

【解决方案2】：

Replace 

    <style>
        .Square{
        width:60px;
        height 60px;
        text-align:center;
        font-size: 18pt;
        font-weight: bold;
        font-family: Verdana;
        }
    </style>

With

<style>
        .Square{
        width:60px;
        height:60px;
        text-align:center;
        font-size: 18pt;
        font-weight: bold;
        font-family: Verdana;
        }
    </style>

you missed : after height.
