css - 卡片悬停推到顶部效果

Question

嗨，我试图在我的文本中推动顶部，我使用了 opacity: 0 并且当它悬停时我使用填充底部但是当这个隐藏文本的高度很高时我会遇到这个问题，因为它将继续占用这个空间，因为它不与显示没有我无法解决这个问题：

但我需要我的文本位于 div 的末尾，如下所示：

它不会从我的 div 末尾开始，因为即使不透明度为 0，我的文本仍然存在

代码：

 <TestingLive isHover={hoveredCards.card1}>
        <div
          className="a"
          onMouseOver={() => updateHoveredCards("card1", true)}
          onMouseOut={() => updateHoveredCards("card1", false)}
        >
          <div className="content-header">
            <p className="text-title">testing</p>
            <h3 className="content-text" style={{ color: "#fff" }}>
              testing
            </h3>
            <p className="date-text" style={{ color: "#fff" }}>
              <span>a</span>

            </p>
            <p className="content-spoiler">
              show this text bottom on hover show this text bottom on hover show
              this text bottom on hover show this text bottom on hover
            </p>
