<p>当我悬停在一个div上时，我希望有一个从左到右滑动的覆盖层，然后在1秒延迟后内容变得可见。这是我的HTML代码：</p> <p><br /></p> <pre class="brush:css;toolbar:false;">/* 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; }</pre> <pre class="brush:html;toolbar:false;"><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></pre> <p><br /></p> <p>当您悬停在图像上时，可以看到白色背景会滑动，内部内容将会显示出来。我想要延迟1秒才显示。您能帮助我吗？谢谢。</p>
