读心术小游戏
主要用到知识点
- css3 2d转换 与过渡
- css 使用less
- display:grid 布局 repeat()方法
- fr单元是允许你用等分网格容器剩余可用空间来设置(简单来说就是占容器的几份)
- 效果图
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>
