Question

好吧，可能有这样的问题，但我在Google的前10页找不到任何内容。所以，我正在为我的网站创建一个背景幻灯片，我在幻灯片中有6张图片。

我的问题是，在进行每次转换时，我无法阻止文本消失。这是我的代码：

HTML

<ul class="bg-slideshow">
<li>
    <span>Image 1</span>
    <div> 
    </div>
</li>
<li>
    <span>Image 2</span>
    <div>
    </div>
</li>
<li>
    <span>Image 3</span>
    <div>
    </div>
</li>
<li>
    <span>Image 4</span>
    <div>
    </div>
</li>
<li>
    <span>Image 5</span>
    <div>
    </div>
</li>
<li>
    <span>Image 6</span>
    <div>
    </div>
</li>

CSS

.bg-slideshow,
.bg-slideshow:after { 
    position: fixed;
    width: 100%;
    height: 100%;
    top: 0px;
    left: 0px;
    z-index: 0; 
}

.bg-slideshow li span { 
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0px;
    left: 0px;
    color: black;
    background-size: cover;
    background-position: 50% 50%;
    background-repeat: none;
    opacity: 0;
    z-index: 0;
    animation: imageAnimation 36s linear infinite 0s; 
}

.bg-slideshow li:nth-child(1) span { 
    background-image: url("image2.png") 
}
.bg-slideshow li:nth-child(2) span { 
    background-image: url("image2.png");
    animation-delay: 6s; 
}
.bg-slideshow li:nth-child(3) span { 
    background-image: url("image3.png");
    animation-delay: 12s; 
}
.bg-slideshow li:nth-child(4) span { 
    background-image: url("image4.png");
    animation-delay: 18s; 
}
.bg-slideshow li:nth-child(5) span { 
    background-image: url("image5.png");
    animation-delay: 24s; 
}
.bg-slideshow li:nth-child(6) span { 
    background-image: url("image6.png");
    animation-delay: 30s; 
}

.bg-slideshow li:nth-child(2) div { 
    animation-delay: 6s; 
}
.bg-slideshow li:nth-child(3) div { 
    animation-delay: 12s; 
}
.bg-slideshow li:nth-child(4) div { 
    animation-delay: 18s; 
}
.bg-slideshow li:nth-child(5) div { 
    animation-delay: 24s; 
}
.bg-slideshow li:nth-child(6) div { 
    animation-delay: 30s; 
}

.bg-slideshow li div { 
    z-index: 1000;
    position: absolute;
    bottom: 30px;
    left: 0px;
    width: 100%;
    text-align: center;
    opacity: 0;
    color: #fff;
    animation: titleAnimation 36s linear infinite 0s; 
}

@keyframes imageAnimation { 
    0% { opacity: 0; animation-timing-function: ease-in; }
    8% { opacity: 0; animation-timing-function: ease-out; }
    17% { opacity: 0 }
    25% { opacity: 0 }
    100% { opacity: 0 }
}

@keyframes titleAnimation { 
    0% { opacity: 0 }
    8% { opacity: 0 }
    17% { opacity: 0 }
    19% { opacity: 0 }
    100% { opacity: 0 }
}

.no-cssanimations .bg-slideshow li span {
    opacity: 1;
}

 @media screen and (max-width: 1140px) { 
    .bg-slideshow li div h3 { font-size: 140px }
}
@media screen and (max-width: 600px) { 
    .bg-slideshow li div h3 { font-size: 80px }
}

@keyframes imageAnimation { 
    0% {
    opacity: 0;
    animation-timing-function: ease-in;
}
8% {
    opacity: 1;
    transform: scale(1.05);
    animation-timing-function: ease-out;
}
17% {
    opacity: 1;
    transform: scale(1.1) rotate(3deg);
}
25% {
    opacity: 0;
    transform: scale(1.1) rotate(3deg);
}
100% { 
    opacity: 0
}

@keyframes titleAnimation { 
0% {
    opacity: 0;
    transform: translateX(200px);
}
8% {
    opacity: 1;
    transform: translateX(0px);
}
17% {
    opacity: 1;
    transform: translateX(0px);
}
19% {
    opacity: 0;
    transform: translateX(-400px);
}
25% { opacity: 0 }
100% { opacity: 0 }
}

我错过了什么？我一次又一次地看过这个。（再次。）谢谢！

我认为你只需要在你想要在幻灯片上显示的容器中添加定位/ z-index，如下所示：

.welcome, .category_1, .category_2, .category_3{
  position: relative;
  z-index: 1;
}
