我试图让div从一个背景渐变转换到另一个背景渐变。我有一个磁性滚动效果设置,以便当用户向下滚动或按下箭头键时,h1标题会改变,背景渐变会缓慢转换为另一个渐变。我有磁性滚动和h1效果工作正常。我甚至应该在他们应该的时候改变背景渐变。问题是我需要这些过渡非常流畅。目前,它们会闪烁到下一个渐变。我现在已经尝试了几周的各种黑客攻击,似乎无法正常工作。立即访问该项目alopexid.com。
我的jQuery:
jQuery(document).ready(function($) {
$(document).foundation

$(window).scroll(function(event){
var currentHeight = $('body').scrollTop();
//load in static home page if bottom of scroll is reached
//alert(currentHeight);
//grad1
if (currentHeight == 0 && currentHeight < windowHeight){
//$(".home-gradient").css("background", "linear-gradient(135deg, #65c9de 0%, #cbd45a 100%)");

这里的任何帮助都会令人惊叹。我已经阅读了很多关于这不可能的评论,但这些评论大多是在2到5年前。必须有某种插件或解决方法。在此先感谢您的帮助!

背景渐变并不支持transition
,但是您可能会破解这会创建另一个div
,其z-index
比您的身体大一些,或者包含您的渐变但是z-index
更低opacity:0
1}}然后是页面内容和div
,以便您可以将渐变应用于此body
,然后使其可见,最后将渐变应用于div
,将其从{{1}中删除并隐藏它。
我知道,因为你不知道如何做到这一点,所以DEMO会帮助你。
但是,我建议不要使用此策略来避免背景渐变过渡,并保持网站现在的状态。

您是否尝试过使用ScrollReveal.js?您应该能够自定义它以便能够转换不同的背景。它允许您通过设置delay
属性来控制转换。我在我的一些网页中使用过此库,它非常易于使用,您可以将其传递给几乎任何元素。
