我想在悬停叠加层之前和之后添加延迟内容

Question

当我将鼠标悬停在 div 上时，我想要一个从左向右滑动的叠加层，然后在 1 秒延迟后内容可见。这是我的 HTML 代码：

/* overlay */

.overlay {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: rgba(255, 255, 255, 0.9);
  overflow: hidden;
  width: 0;
  height: 100%;
  transition: .5s ease;
}

.dv-each:hover .overlay {
  /* transition-delay: 0.4s; */
  transition: .5s ease-in-out;
  width: 100%;
}

.overlay-content {
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  white-space: nowrap;
}

<div class="col-12 col-md-5 col-lg-4 p-0 m-1 dv-each position-relative h-75">
  <a href="{{ route('xdsoft.tintuc')}}">
    <img src="{{ asset('image/TrangChu/rectangleLogo4.png') }}" class="img-fluid w-100" alt="...">
    <div class="overlay">
      <div class="text w-100 h-100 overlay-content px-3 py-4">
        <div class="fs-4">
          {{-- Some text --}}
        </div>
        {{--
        <div style="display: flex; justify-content: flex-end;">
          <a href="{{ route('xdsoft.thietke')}}">
            <div class="bg-145982 text-white p-2">Xem thêm</div>
          </a>
        </div> --}}
      </div>
    </div>
  </a>
</div>

正如您所看到的，当我将鼠标悬停在图像上时，白色背景会滑动，里面的内容就可见。我想让它延迟1秒。你能帮助我吗？谢谢。

我希望这就是您正在寻找的。

请更改照片的 URL。我用的是网上的一个。

  .overlay {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: rgba(255, 255, 255, 0.9);
  overflow: hidden;
  width: 0;
  height: 100%;
  transition: .5s ease;
  transition-delay: 1s;
  /* Set Delay Duration */
}

.dv-each:hover .overlay {
  transition: .5s ease-in-out;
  width: 100%;
  transition-delay: 0s;
}

.overlay-content {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  white-space: nowrap;
  opacity: 0;
  transition: opacity 1s ease;
  .dv-each:hover .overlay-content {
    opacity: 1;
  }

<div class="col-12 col-md-5 col-lg-4 p-0 m-1 dv-each position-relative h-75">
  <a href="{{ route('xdsoft.tintuc')}}">
    <img src="https://cdn.pixabay.com/photo/2015/04/23/22/00/tree-736885_1280.jpg" class="img-fluid w-100" alt="...">
    <div class="overlay">
      <div class="text w-100 h-100 overlay-content px-3 py-4">
        <div class="fs-4">
          Text Displayed after Delay
        </div>
        <div style="display: flex; justify-content: flex-end;">
          <a href="{{ route('xdsoft.thietke')}}">Text Displayed after Delay
                                <div class="bg-145982 text-white p-2"></div>
                              </a>
        </div>
      </div>
    </div>
  </a>
</div>

将背景图像、叠加层和叠加内容视为三个相互堆叠的独立层。然后就这样编码。

在您的

:hover

规则中，将

transition-delay

设置为悬停开始时所需的延迟，然后在基本规则中将

transition-delay

设置为悬停结束时所需的延迟。

.d1 {
  position: relative;
  height: 100px;
  margin-bottom: 20px;
}
.i1, .overlay, .content {
  position: absolute;
}
.i1, .overlay {
  top: 0;
  left: 0;
  height: 100%;
}
.i1 {
  width: 100%;
  object-fit: cover;
  object-position: center;
}
.overlay {
  width: 0;
  background-color: rgba(255, 255, 255, 0.9);
  transition: .5s .5s ease; /* delay when overlay is removed */
}
.d1:hover .overlay {
  width: 100%;
  transition: .5s ease; /* no delay when overlay is added */
}
.content {
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  white-space: nowrap;
  opacity: 0;
  transition: .5s ease; /* no delay when content is removed */
}
.d1:hover .content {
  opacity: 1;
  transition: .5s .5s ease; /* delay when content is added */
}

<div class="d1">
  <img class="i1" src="https://picsum.photos/1000/200">
  <div class="overlay"></div>
  <div class="content">Content appears</div>
</div>

<div class="d1">
  <img class="i1" src="https://picsum.photos/1000/200">
  <div class="overlay"></div>
  <div class="content">Content appears</div>
</div>
