我在网上看到了很酷的滚动效果...
滚动查看各部分时图像与下一张图像融合的位置。我一直在尝试重现它,但似乎无法弄清楚?如何在网络上创建此效果?
这是我看到效果的链接... http://readingbuddysoftware.com/how-it-works/
我尝试position: fixed
在屏幕截图中使用z-index
,该部分的高于图像,但最后一个屏幕截图始终位于顶部。
有任何想法吗?
更新:由于各种原因(包括放置,使用倾斜...),我无法使用background-image
css解决方案。我需要使用<img>
元素的解决方案。
可以使用和两个类似的图像来完成。background-attachement
:fixed
这是一个简单的示例:
body {
min-height:200vh;
margin:0;
background:url(https://picsum.photos/id/1069/150/150?grayscale) 20px 20px no-repeat;
background-attachment:fixed;
}
.box {
margin-top:220px;
height:200px;
background:url(https://picsum.photos/id/1069/150/150) 20px 20px no-repeat,
grey;
background-attachment:fixed;
}
<div class="box">
</div>
您可以轻松缩放许多图像:
body {
min-height:250vh;
margin:0;
background:url(https://picsum.photos/id/1069/150/150?grayscale) 50px 50px/auto no-repeat;
background-attachment:fixed;
}
.box {
height:200px;
background:url(https://picsum.photos/id/1069/150/150) 50px 50px/auto no-repeat,
grey;
background-attachment:fixed;
}
.box:first-child {
margin-top:200px;
}
<div class="box">
</div>
<div class="box" style="background-image:url(https://picsum.photos/id/11/150/150);background-color:yellow">
</div>
<div class="box" style="background-image:url(https://picsum.photos/id/106/150/150);background-color:pink">
</div>
您也可以考虑使用img
和,position:fixed
但是您将需要一些技巧来隐藏使用clip-path
body {
min-height: 250vh;
margin: 0;
padding-top: 100px;
}
img {
position: fixed;
top: 50px;
left: 50px;
}
.box {
height: 200px;
background: grey;
clip-path:polygon(0 0,100% 0,100% 100%,0 100%);
}
<div class="box">
<img src="https://picsum.photos/id/1074/200/120?grayscale">
</div>
<div class="box" style="background-color:red;">
<img src="https://picsum.photos/id/1074/200/120">
</div>
<div class="box" style="background-color:yellow;">
<img src="https://picsum.photos/id/1024/200/120?grayscale">
</div>
<div class="box" style="background-color:pink;">
<img src="https://picsum.photos/id/1024/200/120">
</div>
或使用 mask
body {
min-height: 250vh;
margin: 0;
padding-top: 100px;
}
img {
position: fixed;
top: 50px;
left: 50px;
}
.box {
height: 200px;
background: grey;
-webkit-mask:linear-gradient(#fff,#fff);
mask:linear-gradient(#fff,#fff);
}
<div class="box">
<img src="https://picsum.photos/id/1074/200/120?grayscale">
</div>
<div class="box" style="background-color:red;">
<img src="https://picsum.photos/id/1074/200/120">
</div>
<div class="box" style="background-color:yellow;">
<img src="https://picsum.photos/id/1024/200/120?grayscale">
</div>
<div class="box" style="background-color:pink;">
<img src="https://picsum.photos/id/1024/200/120">
</div>
为了获得更好的支持,这与某些JS类似,以避免使用clip-path或mask
我将使用CSS变量更新图片的位置,但您可以轻松地做到以下几点:
window.onscroll = function() {
var scroll = window.scrollY || window.scrollTop || document.getElementsByTagName("html")[0].scrollTop;
document.documentElement.style.setProperty('--scroll-var', scroll+"px");
}
:root {
--scroll-var: 0px;
}
body {
min-height: 150vh;
margin: 0;
}
img {
position: fixed;
top: 20px;
left: 20px;
}
.box {
margin-top: 220px;
height: 200px;
background: grey;
position: relative;
overflow: hidden;
}
.box img {
top: calc(-220px + 20px + var(--scroll-var));
/* margin of box + top of the other image + scroll*/
position: absolute;
}
<img src="https://picsum.photos/id/1069/150/150?grayscale">
<div class="box">
<img src="https://picsum.photos/id/1069/150/150">
</div>
有许多图像:
window.onscroll = function() {
var scroll = window.scrollY || window.scrollTop || document.getElementsByTagName("html")[0].scrollTop;
document.documentElement.style.setProperty('--scroll-var', scroll+"px");
}
:root {
--scroll-var: 0px;
}
body {
min-height: 250vh;
margin: 0;
padding-top:200px;
}
img {
position: fixed;
top: 50px;
left: 50px;
}
.box {
height: 200px;
background: grey;
position: relative;
overflow: hidden;
}
img.f1 {
top: calc(-200px + 50px + var(--scroll-var));
position: absolute;
}
img.f2 {
top: calc(-400px + 50px + var(--scroll-var));
position: absolute;
}
img.f3 {
top: calc(-600px + 50px + var(--scroll-var));
position: absolute;
}
<img src="https://picsum.photos/id/1069/100/100?grayscale">
<div class="box">
<img class="f1" src="https://picsum.photos/id/1069/100/100">

<div class="box" style="background-color:yellow;">
<img class="f2" src="https://picsum.photos/id/107/100/100">

<div class="box" style="background-color:pink;">
