这是一款使用 CSS3 帧动画来制作的炫酷 404 页面动画特效。该 404 页面以书架为主题,当某个页面不存在时,以书架中找不到这本书来表示,非常有创意。
该 404 页面使用一个<nav>元素来作为导航。
<nav class="shelf">
<a class="book home-page">Home page</a>
<a class="book about-us">About us</a>
<a class="book contact">Contact</a>
<a class="book faq">F.A.Q.</a>
<span class="book not-found"></span>
<span class="door left"></span>
<span class="door right"></span>
</nav>
<h1>Error 404</h1>
<p>糟糕,您要找的书籍不在书架中。。。</p>
整个页面使用 flexbox 来进行布局。
body {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
margin: 0;
padding: 0;
background-color: #446072;

flex-direction: column;
overflow: hidden;
}
.shelf 元素是书架,里面是一些导航按钮。它使用相对定位,为了制作开门的 3D 动画效果,为它设置了 perspective 透视度。
.shelf {
position: relative;
width: 30rem;
height: 14rem;
border: 0.5rem solid #374d5b;
border-radius: 0.5rem;
background-color: rgba(255, 255, 255, 0.1);
-webkit-perspective: 130rem;
perspective: 130rem;
box-shadow: inset 0 0 2rem rgba(0, 0, 0, 0.2);
}
.door 是左右两扇书架门,它的:before 伪元素用来制作门的手柄。
.door {
position: absolute;
width: 14.8rem;
height: 14rem;
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
box-sizing: border-box;
padding: 1rem;
background-color: #374d5b;
-webkit-box-align: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.3);
}
.door::before {
width: 1.5rem;
height: 1.5rem;
border-radius: 50%;
background-color: rgba(0, 0, 0, 0.1);
content: "";
}
左侧的门的 transform-origin 被设置在 0 0 0 位置,及左上角位置,并执行 leftDoorOpen 和 leftDoorFlap 两个帧动画。
.door.left {
border-radius: 0 0.75rem 0.75rem 0;
-webkit-box-pack: end;
-webkit-justify-content: flex-end;
-ms-flex-pack: end;
justify-content: flex-end;
-webkit-animation:
leftDoorOpen 3.5s ease-out forwards 1s,
leftDoorFlap 15s linear infinite forwards 9s;
animation:
leftDoorOpen 3.5s ease-out forwards 1s,
leftDoorFlap 15s linear infinite forwards 9s;
-webkit-transform-origin: 0 0 0;
transform-origin: 0 0 0;
}
@keyframes leftDoorOpen {
60% {-webkit-transform: rotateY(-115deg);transform: rotateY(-115deg)}
100% {-webkit-transform: rotateY(-110deg);transform: rotateY(-110deg)}
}
@keyframes leftDoorFlap {
0% { -webkit-transform: rotateY(-110deg); transform: rotateY(-110deg)}
5% {-webkit-transform: rotateY(-115deg);transform: rotateY(-115deg)}
15% {-webkit-transform: rotateY(-107deg);transform: rotateY(-107deg)}
25% {-webkit-transform: rotateY(-113deg);transform: rotateY(-113deg)}
30% {-webkit-transform: rotateY(-110deg);transform: rotateY(-110deg)}
100% {-webkit-transform: rotateY(-110deg);transform: rotateY(-110deg)}
}
右侧的门的转换圆点设置在 100% 0 0 位置,并执行 rightDoorOpen 和 rightDoorFlap 两个帧动画。
.door.right {
right: 0;
border-radius: 0.75rem 0 0 0.75rem;
-webkit-animation:
rightDoorOpen 3s ease-out forwards 1.5s,
rightDoorFlap 10s linear infinite forwards 8s;
animation:
rightDoorOpen 3s ease-out forwards 1.5s,
rightDoorFlap 10s linear infinite forwards 8s;
-webkit-transform-origin: 100% 0 0;
transform-origin: 100% 0 0;
}
@keyframes rightDoorOpen {
60% {-webkit-transform: rotateY(125deg);transform: rotateY(125deg)}
100% {-webkit-transform: rotateY(120deg);transform: rotateY(120deg)}
}
@keyframes rightDoorFlap {
0% { -webkit-transform: rotateY(120deg); transform: rotateY(120deg)}
5% {-webkit-transform: rotateY(125deg);transform: rotateY(125deg)}
15% {-webkit-transform: rotateY(117deg);transform: rotateY(117deg)}
25% {-webkit-transform: rotateY(123deg);transform: rotateY(123deg)}
30% {-webkit-transform: rotateY(120deg);transform: rotateY(120deg)}
100% {-webkit-transform: rotateY(120deg);transform: rotateY(120deg)}
}
几个链接元素被制作为圆角矩形,并使用 transform 函数将它们旋转和移动到相应的位置。.not-found 元素还会执行一个闪烁动画 bookFadeOut。
.book {
position: absolute;
box-sizing: border-box;
padding: 0.8rem 4rem 0.8rem 2rem;
border-radius: 0.25rem;
background-color: rgba(255, 255, 255, 0.1);
color: white;
font-size: 1rem;
text-transform: uppercase;
letter-spacing: 0.1rem;
cursor: pointer;
box-shadow: inset 0 0 0.75rem rgba(255, 255, 255, 0.1);
}
.book.home-page {
-webkit-transform: rotate(-90deg) translate(-12.4rem, 3rem);
transform: rotate(-90deg) translate(-12.4rem, 3rem);
-webkit-transform-origin: 0;
transform-origin: 0;
}
.book.about-us {
-webkit-transform: rotate(-100deg) translate(-13.4rem, 6.1rem);
transform: rotate(-100deg) translate(-13.4rem, 6.1rem);
-webkit-transform-origin: 0;
transform-origin: 0;
}
.book.contact {
right: 2rem;
bottom: 0.2rem;
border-radius: 0.3rem 0 0 0.3rem;
}
.book.faq {
right: 0.8rem;
bottom: 3.3rem;
border-radius: 0.3rem 0 0 0.3rem;
}
.book.not-found {
width: 12rem;
height: 3.5rem;
border: 1px dashed rgba(255, 255, 255, 0.3);
background-color: transparent;
-webkit-transform: rotate(-90deg) translate(-12rem, 13rem) scale(1);
transform: rotate(-90deg) translate(-12rem, 13rem) scale(1);
-webkit-transform-origin: 0;
transform-origin: 0;
