###主要用到知识点

Alt

 ###html:

   <div class="wraper">
        <div class="left">
            <div class="board">
                <img class="img" src="./img/round.png" alt="">
                <img class="tuan" src="./img/values/0.png" alt="">
            </div>
            <p>在心中任意选择一个两位数(或者说,从10~99之间任意选择一个数),把这个数字分别减去其十位数和个位数(例如你选择的是71,那就:71-7-1=63)。</p>
            <br />
            <p>在右边图表中找出与最后得出的数所相应的图形,并把这个图形牢记心中,然后点击上方的阵型。你会发现,阵型所显示出来的图形就是你刚刚心里记下的那个图形。</p>
        </div>
        <div class="right">
        </div>
    </div>
