如何在悬停过渡期间使文本平移/宽度增加

Question

我有一个 .card，它默认显示一个箭头。当用户将鼠标悬停在此 .card 上时，我希望“了解更多”文本从右侧滑入并移动箭头。

我试过把.card__footer改成width: 0；然后尝试在悬停时给它width，但是，因为文本正在过渡，有时它会出现在两行上，然后一旦过渡结束，就会变成一行。

除了使用 width 之外，我如何才能在悬停时使用此效果？或者什么是正确的实施方式？我目前的做法：

.cards {
  background: lightblue;
  padding: 60px 0;
}

.container {
  max-width: 720px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin: 0 auto;
}

.card {
  background-color: white;
  padding: 30px;
  cursor: pointer;
  transition: all 0.5s ease;
  width: 250px;
}
.card:hover {
  box-shadow: 0px 20px 25px 0px rgba(0, 0, 0, 0.1);
}
.card:hover .card__arrow {
  transform: translateX(5px);
}
.card:hover .card__label {
  display: inline-block;
  visibility: visible;
  margin-right: 6px;
  opacity: 1;
}
.card__header {
  margin-bottom: 30px;
}
.card__footer {
  display: flex;
  justify-content: flex-start;
  align-items: center;
}
.card__label {
  margin-right: 10px;
}
@media (hover: hover) {
  .card__label {
    margin: 0;
    transition: opacity 0.5s;
    visibility: hidden;
    opacity: 0;
    display: none;
  }
}

<div class="cards">
  <div class="container">

    <div class="card">
      <div class="card__header">
        header
      </div>
      <div class="card__footer">
        <span class="card__label">Learn more</span>
        <img class="card__arrow" src="https://i.imgur.com/onjXVGW.png" alt="arrow" />
      </div>
    </div>

    <div class="card">
      <div class="card__header">
        header 2
      </div>
      <div class="card__footer">
        <span class="card__label">Learn more</span>
        <img class="card__arrow" src="https://i.imgur.com/onjXVGW.png" alt="arrow" />
      </div>
    </div>


  </div>
</div>

我追求的是：

.footer__arrow 默认显示左侧（与演示中一样）
.footer__label 默认隐藏
在 .card 悬停时，我希望 .footer__label 滑入，推动 arrow 图像（以便它显示“了解更多”，然后在悬停时显示箭头.
目前我的 .footer__label 刚刚出现，而我希望标签慢慢滑入并赋予它我的箭头被推到旁边的效果。

不完全确定这是您要的，但希望它能让您对您的尝试有所了解。

.cards {
  background: lightblue;
  padding: 60px 0;
}

.container {
  max-width: 720px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin: 0 auto;
}

.card {
  background-color: white;
  padding: 30px;
  cursor: pointer;
  transition: all 0.5s ease;
  width: 250px;
}

.card:hover {
  box-shadow: 0px 20px 25px 0px rgba(0, 0, 0, 0.1);
}

.card:hover .card__arrow {
  transform: translateX(5px);
}

.card:hover .card__label {
  display: inline-block;
  visibility: visible;
  margin-right: 6px;
}

.card__header {
  margin-bottom: 30px;
}

.card__footer {
  display: flex;
  justify-content: flex-start;
  align-items: center;
}

.card .card__footer::after {
  content: "";
  transform: translateX(60px);
  transition: transform .5s linear;
    

}

.card:hover .card__footer::after {
  transform: translateX(36px);
  content: "Learn More";
  transition:transform .5s linear;

}

.card__label {
  margin-right: 10px;
}

@media (hover: hover) {
  .card__label {
    margin: 0;
    transition: opacity 0.5s;
    visibility: hidden;
    opacity: 0;
    display: none;
  }
}

Using transform: 您可以为标签和箭头引入一个包装器。然后在悬停时将其转换为右侧。在页脚上隐藏溢出：

:root {
  --arrow-icon-size: 1.5rem;
}

.cards {
  background: lightblue;
  padding: 25px 0;
}

.container {
  max-width: 720px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin: 0 auto;
}

.card {
  background-color: white;
  padding: 20px;
  cursor: pointer;
  transition: all 0.5s ease;
  width: 250px;
  border-radius: 1rem;
  margin: 0 0.5rem;
}

.card__header {
  margin-bottom: 30px;
}

.card__footer {
  overflow: hidden;
}

.card__slide {
  display: flex;
  justify-content: flex-start;
  align-items: center;
  width: fit-content;
  
  transform: translateX(calc(-100% + var(--arrow-icon-size)));
  transition: transform 1s ease-out;
}

.card__label {
  display: inline-block;
  margin-right: 0.3rem;
}

.card__arrow {
  color: #FF7C81;
  font-size: var(--arrow-icon-size);
}

@media (hover: hover) {
  .card:hover {
    box-shadow: 0px 20px 25px 0px rgba(0, 0, 0, 0.4);
  }
  .card:hover .card__slide {
    transform: translateX(0);
  }
}

          <span class="card__label">Learn more</span>
          <i class="card__arrow fas fa-chevron-circle-right"></i>

    <div class="card">

使用宽度：可以通过过渡标签宽度实现显示效果：

    .cards {
      background: lightblue;
      padding: 20px 0;
    }

    .container {
      max-width: 720px;
      display: flex;
      justify-content: space-between;
      align-items: center;
      margin: 0 auto;
    }

    .card {
      background-color: white;
      padding: 20px;
      cursor: pointer;
      transition: all 0.5s ease;
      width: 250px;
      border-radius: 1rem;
      margin: 0.5rem;
    }

    .card__header {
      margin-bottom: 30px;
    }

    .card__footer {
      display: flex;
      justify-content: flex-start;
      align-items: center;
      width: fit-content;
    }

    .card__label {
      display: inline-block;
      width: 0;
      overflow: hidden;
      white-space: nowrap;

      transition: width 1s ease-out;
      margin-right: 0.3rem;
    }

    .card__arrow {
      color: #FF7C81;
      font-size: 1.5rem;
    }

    @media (hover: hover) {
      .card:hover {
        box-shadow: 0px 20px 25px 0px rgba(0, 0, 0, 0.4);
      }

      .card:hover .card__label {
        width: 100%;
      }
    }

          <i class="card__arrow fas fa-chevron-circle-right"></i>
      </div>
    </div>

    <div class="card">
      <div class="card__header">header 2</div>
      <div class="card__footer">
          <span class="card__label">Learn more</span>
          <i class="card__arrow fas fa-chevron-circle-right"></i>
      </div>
    </div>

  </div>
</div>

Imgur 在其 CORS 政策中不允许某些来源。所以对于演示，我使用 fontawesome chevron-circle-right 作为箭头。
