Inhalt beim Hover anzeigen (hat keinen Einfluss auf die Kartenhöhe)

Ich habe einen Block, der Inhalte enthält, die beim Hover angezeigt werden. Der Effekt sollte wie folgt wirken:

Das Problem, auf das ich gestoßen bin, ist:

Gibt es eine Möglichkeit, dieses Problem zu lösen? Ich verwende nicht unbedingt GSAP, ich habe GSAP nur ausprobiert, um das oben genannte Problem zu lösen.

const hoverCard = document.querySelector('.hoverCard');
const hoverCardBodyShowOnHover = document.querySelector('.hoverCard__showOnHover');

hoverCard.addEventListener('mouseenter', function() {
  gsap.to(hoverCardBodyShowOnHover, { duration: 0.5, display: 'block', height: 'auto', ease: 'power4.out' });
});

hoverCard.addEventListener('mouseleave', function() {
  gsap.to(hoverCardBodyShowOnHover, { duration: 0.5, height: 0, ease: 'power4.out', onComplete: function() {
    this.targets()[0].style.display = 'none';
  }});
});

So sieht die Standardversion der Karte optisch aus (rechte Karte) und wie die Hover-Interaktion funktioniert (linke Karte):

Beachten Sie, dass sich die Kartenhöhe nicht erhöht hat. Stattdessen bewegt sich der Körper nach oben (innerhalb der Karte), um den Inhalt preiszugeben.

Müssen wir außerdem eine Zahl für max-height: 100px; definieren? Was passiert, wenn die Inhaltsgröße unbekannt ist und dynamisch sein muss?

    技巧是将要显示的文本设置为 max-height: 0 overflow: hide。这是一个最小可重现示例

    body {
      margin: 1rem;
      font-family: system-ui, sans-serif;
    }
    
    .item {
      position: relative;
      overflow: hidden;
      margin-right: 0.8rem;
      width: 150px;
      float: left;
      border: 1px solid #777;
      border-radius: 3px;
    }
    
    .item.first {
      background: url("https://upload.wikimedia.org/wikipedia/commons/d/d0/Queen_Clementia_of_Hungary.jpg") no-repeat top left;
      background-size: cover;
      height: 150px;
    }
    
    .collapsible {
      height: inherit;
      width: inherit;
      position: absolute;
      bottom: 0;
    }
    
    .collapsible .header {
      background-color: #EEE;
      color: #000;
      text-align: center;
      font-weight: bold;
      font-size: 0.9rem;
      cursor: pointer;
      bottom: 0;
      width: 100%;
      position: absolute;
      opacity: 0.8;
    }
    
    .item .collapsible .collapsibleTxt {
      max-height: 0;
      text-align: left;
      font-size: initial;
      color: #444;
      overflow: hidden;
      padding: 4px;
      font-weight: normal;
      transition: max-height 0.5s ease-in-out;
    }
    
    .header:hover  .collapsibleTxt {
      overflow: initial;
      height: auto;
      max-height: 100px;
    }
