我正在尝试在视频播放按钮上显示通知。实际上,单击按钮单击即可播放视频。我知道要显示一个带有播放图标内容的div。但是,我想淡出播放图标,可以说5秒后。我想使用CSS实现它。以下是我的尝试。如果有更好的解决方案,请在此通知我。
body {
font-size: 50%;
font-style: Arial;
}
.animation-box {
width: 75%;
height: 27.5rem;
background-color: blue;
margin: 0 auto;
overflow: hidden;
position: relative;
}
.animation-container {
width: 1000rem;
height: 30rem;
}
.first-text {
font-size: 4rem;
position: absolute;
left: 2.5rem;
top: 5rem;
color: white;
-webkit-animation: fadeOut 2s forwards;
animation: fadeOut 2s forwards;
-webkit-animation-delay: 5s;
animation-delay: 5s;
}
.first-text:hover {
-webkit-animation: fadeIn 0s forwards;
animation: fadeIn 0s forwards;
-webkit-animation-delay: 0.5s;
animation-delay: 0.5s;
}
@-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
@keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
@-webkit-keyframes fadeOut {
from {opacity: 1;}
to {opacity: 0;}
}
@keyframes fadeOut {
from {opacity: 1;}
to {opacity: 0;}
}
<section class="animation-box">
<h1 class="first-text">This is auto fade out after hover </h1>
</section>
您仅需transition
即可实现:
body {
font-size: 50%;
font-style: Arial;
}
.animation-box {
width: 75%;
height: 27.5rem;
background-color: blue;
margin: 0 auto;
overflow: hidden;
position: relative;
}
h1{
opacity:0;
transition: opacity 250ms 5s ease;
}
.animation-box:hover h1{
opacity:1;
transition-delay: 250ms;
}
<section class="animation-box">
<h1 class="first-text">This is auto fade ou1t after hover </h1>
</section>
