带有按钮的CSS弹出窗口关闭

Question

我正在使用CSS来控制和显示我的页面上的POPUP，一切正常，但我想要Okay按钮关闭弹出窗口而不是通过单击右上角的十字按钮关闭它。有没有办法在css中这样做。或者我能为此做些什么。

    .box {
      width: 40%;
      margin: 0 auto;
      background: rgba(255,255,255,0.2);
      padding: 35px;
      border: 2px solid #fff;
      border-radius: 20px/50px;
      background-clip: padding-box;
      text-align: center;
    }
    
    .button {
      font-size: 1em;
      padding: 10px;
      color: #fff;
      border: 2px solid #06D85F;
      border-radius: 20px/50px;
      text-decoration: none;
      cursor: pointer;
      transition: all 0.3s ease-out;
    }
    .button:hover {
      background: #06D85F;
    }
    
    .popup h2 {
      margin-top: 0;
      color: #333;
      font-family: Tahoma, Arial, sans-serif;
    }
    .popup .close {
      position: absolute;
      top: 20px;
      right: 30px;
      transition: all 0.2s;
      font-size: 30px;
      font-weight: bold;
      text-decoration: none;
      color: #333;
    }
    .popup .close:hover {
      color: #06D85F;
    }
    .popup .content {
      max-height: 30%;
      overflow: auto;
    }
    
    /*Let's make it appear when the page loads*/
    .overlay:target:before {

    .popup .close {
      display:block;
      border:1px solid darkblue;
      text-align:center;
      background: steelblue;
      color:white;
      border-radius:5px;
      padding:5px;
    }
    .popup .close:hover {

    }
    .popup .content {
      max-height: 30%;
      overflow: auto;
    }
    
    /*Let's make it appear when the page loads*/
    .overlay:target:before {
