当我滚动时,我试图将3个(全屏)div相互淡化。
我一直在尝试使用Skrollr(https://github.com/Prinzhorn/skrollr),它有一些工作但有一个奇怪的问题。
当我向下滚动图像淡入淡出但是'.intro-bg'从页面顶部开始,然后移动到页面的大约一半。 '.sign-up-bg'很好,不滚动它保持固定在顶部,'welcome-bg'也是如此。所以这只是中间的痛苦。
我创建了一个小提琴来尝试复制事物http://jsfiddle.net/9HFd9/它不完全相同,但这里也有滚动问题。
以下是代码:
HTML:
<div class="content">
<div class="welcome">Welcome</div>
<div class="intro">Intro</div>
<div class="sign-up">Sign Up</div>
</div>
<div class="welcome-bg" data-0="opacity:1;" data-500="opacity:0;"></div>
<div class="intro-bg" data-500="opacity:1;" data-1000="opacity:0;"></div>
<div class="sign-up-bg" ></div>
使用Javascript:
skrollr.init({
smoothScrolling: true,
forceHeight: false
});
var maxWidth = $(window).width();
var maxHeight = $(window).height();
$(document).ready(function(){
$('.welcome, .intro, .sign-up').css({
width: maxWidth,
height: maxHeight
});
});
CSS
.welcome-bg, .intro-bg, .sign-up-bg{
position:fixed;
top:0;
left:0;
width:100%;
height:100%;
}
.welcome-bg{
background: blue url('http://wallpicshd.com/wp-content/uploads/2013/06/Landscape-04-HD-Wallpaper.jpg') center center fixed;
background-size:cover;
z-index:-2;
}
.intro-bg{
background: green url('http://www.hdwallpapers.in/walls/sunflower_landscape-wide.jpg') center center fixed;
z-index:-3;
}
.sign-up-bg{
background: red url('http://www.hdwallpaperstop.com/wp-content/uploads/2013/05/Beautiful-Landscape-Pictures-of-nature.jpg') center center fixed;
z-index:-4;
}
任何想法可能出错?

<div class="welcome-bg" data-0="opacity:1;" data-100p="opacity:0;"></div>
<div class="intro-bg" data-100p="opacity:1;" data-200p="opacity:0;"></div>
并添加
$( window ).resize(function() {
var maxWidth = $(window).width();
var maxHeight = $(window).height();
$('.welcome, .intro, .sign-up').css({
width: maxWidth,
height: maxHeight
});
});
