CSS animation未展示全部成员卡片问题及循环滚动需求

问题根源 #

原代码给每个独立卡片添加了动画，每个卡片仅移动自身宽度的距离就重置，导致无法完整展示所有卡片。要实现完整滚动+无缝循环，需要将动画应用到整个卡片组，而非单个卡片。

修改后的完整代码 #

CSS 部分 #

.team-profile-card-container {
  white-space: nowrap;
  overflow: hidden;
  position: relative;
}

/* 新增卡片包裹层，用于承载动画 */
.team-cards-wrapper {
  display: inline-block;
  animation: slideRightToLeft 15s linear infinite;
}

.team-profile-card {
  display: inline-block;
  width: 200px;
  margin-right: 20px;
  border: 1px solid transparent;
}

/* 修改动画目标为整个卡片组的宽度 */
@keyframes slideRightToLeft {
  0% {
    transform: translateX(0);
  }
  100% {
    /* 移动距离等于整个卡片组的宽度，实现完整滚动 */
    transform: translateX(-100%);
  }
}

.team-profile-card-content {
  background-color: #f8f9fa;
  border-radius: 10px;
  box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
  padding: 20px;
  position: relative;
  overflow: hidden;
}

.team-profile-img {
  width: 150px;
  height: 150px;
  border-radius: 50%;
  overflow: hidden;
  margin: 0 auto 20px;
  transition: transform 0.3s;
}

.team-profile-img:hover {
  transform: scale(1.1);
  box-shadow: 0 0 20px rgba(0, 0, 0, 0.2);
}

.team-profile-name {
  font-size: 18px;
  font-weight: bold;
  margin-bottom: 10px;
}

.team-profile-title {
  font-size: 14px;
  color: #6c757d;
  margin-bottom: 20px;
}

.social-icons {
  position: absolute;
  bottom: 10px;
  left: 50%;
  transform: translateX(-50%);
  opacity: 0;
  transition: opacity 0.3s;
}

.team-profile-card:hover .social-icons {
  opacity: 1;
}

.team-profile-card-container:hover .team-cards-wrapper {
  animation-play-state: paused;
}

.team-profile-card:hover {
  border-color: orangered;
}

.social-icons a {
  color: #007bff;
  font-size: 16px;
  margin: 0 5px;
  transition: color 0.3s;
}

.social-icons a:hover {
  color: #0056b3;
}

关键修改说明 #

1. 动画载体变更：将动画从单个卡片移到包裹所有卡片的.team-cards-wrapper上，确保整个卡片组同步滚动。
2. 无缝循环实现：复制一份完整的卡片组放在原卡片组后面，当第一组完全滚出容器时，第二组刚好衔接，视觉上实现无限循环。
3. 动画参数调整：
   • 动画时长15s可根据卡片数量调整：卡片越多，时长应越长，保证滚动速度均匀。
   • 动画终点设为translateX(-100%)，即滚动整个卡片组的宽度，确保所有卡片都能完整展示。
4. 交互适配：将暂停动画的目标从.team-profile-card改为.team-cards-wrapper，保持hover暂停的交互逻辑正常。
