我想修复包含信息的侧面滚动并将其附加到页脚，如果网页内容发生更改，仍然保持附加。
我遇到这个问题我的右侧滚动包含信息悬停在我的页脚截图下方。 [你可以看到信息卡与页脚重合，请告诉解决方案吗？] [1]
代码是这样的：
var headerscroll = document.getElementById("headerscroll");
// alert(headerscroll.lenght)
var myScrollFunc = function() {
var y = window.scrollY;
//alert(y);
if (y >= 321 && y < 1700) {
$("#headerscroll").css('background-color', '#323232 ');
$("#cooper-crash").css('color', 'white');
$("#cooper-crash").css('font-size', '18px');
$("#headerscroll").css('height', '98px');

我想要这样的事情https://www.udemy.com/bootstrap-to-wordpress。 正如您在本网站所看到的，包含图像和信息的右侧滚动，当滚动到底部时，它会附加到网页的底部（页脚）。
答案 0 :(得分：0)
只需添加以下jQuery代码：
var $window = $(window),
$fixElement = $('.el');
$window.scroll(function() {
if($window.scrollTop() >= $fixElement.offset().top) {
/* propably two options */
// if you will use absolute positioning you have to set top position
$fixElement.css('top', $window.scrollTop + 10);
// if you will use fixed positioning you can just add class
$fixElement.addClass('el--fix');
} else {
// default
}
});
我并不完全具体，但我希望我帮助过。 ：）
