        .wrapper {
            display: grid;
            grid-template-columns: 1fr 1fr;
            /*表示2列*/

            /*第二行的高是第一行的2倍,我们现在可以设置行高之间的关系。如果我们把前面的行高设成 1fr ，最后一个则设置为 3fr，这意味着第二行的行高是第一行的 3 倍：*/
            grid-column-gap: 1px;
            /*列之间的线*/
            grid-row-gap: 1px;
            /*行之间的线隔*/

            }
        }

        @media screen and (min- 800px) {
            /*超过800四列*/

            line-height: 1;
            font-family: 'hobeaux-rococeaux-background', Helvetica;
            font-weight: 200;

<body>
    <div class="wrapper">
        <div class="letter">

        </div>

        <div class="letter">
            Bb
        </div>

        <div class='letter'>
            Cc
        </div>
        <div class='letter'>
            Dd
        </div>
        <div class="letter">
            Ee
        </div>

        <div class="letter">
            Ff
        </div>

        <div class='letter'>
            Gg
        </div>
        <div class='letter'>
            Hh
        </div>
        <div class="letter">

        </div>

        <div class="letter">

        <div class='letter'>
            Kk
        </div>
        <div class='letter'>
            Mm
        </div>

    </div>
</body>

</html>

效果如下：
