html - 获取此 "simon says"游戏中间控件的标题和按钮

Question

我正在开发 Simon Says 游戏，但我无法将标题和按钮从底部放到控件部分的中间。我尝试了不同的 css 样式，但 div 似乎没有移动。

特别是 margin-top 将元素移到更靠近中间的位置。现在它们位于页面底部。这是我到目前为止所拥有的。任何帮助表示赞赏。谢谢

      <div class="strict">STRICT</div>
      <div class="switch">ON/OFF</div>

我确实设置了 .board-controls 的 position:absolute。

并设置.simonBoard的position:relative。

我认为这不是一个好的答案。
