我有一个HTML和CSS栏,它被添加到网站的顶部,需要一些代码才能在向下滚动时将其保持在顶部。
我最好使用JavaScript,或任何有效的东西,我只需要一些东西将它保持在最顶层。
感谢帮助!

9gag.com也使用position:fixed;
作为标题,但在您的情况下,它正在使position:fixed !important
成为解决方案,因为它已被覆盖在您将其放置在您的网站上的位置(在顶部)。
CSS:
#netbar{position:fixed !important;}

在不牺牲suckerfish位置的情况下实现这一目标的最简单方法是使用jQuery,正如您所提到的那样
$(document).ready(function () {
$(window).scroll(function () {
$("#enjin-bar").css({
"top": Math.max($('body').scrollTop(), $('html').scrollTop()) + 4
});
$("#netbar").css({
"top": Math.max($('body').scrollTop(), $('html').scrollTop())
});
});
});
它有效,但是它非常奇怪;只需从您的网站中删除#netbar{position:fixed !important;}
行
或者,如果你愿意为了更少的小故障而牺牲suckereye的位置,请使用此代码:
$(document).ready(function () {
$(window).scroll(function () {
$("#enjin-bar").css({
"top": Math.max($('body').scrollTop(), $('html').scrollTop()) + 4
});
});
});
enjin-bar不是网吧的一部分,这是滚动时不遵循网吧的主要原因,所以绕过这个的最简单方法是使用jQuery

将牧师的代码替换为下面的代码:

<div id="discover" role="directory">

尝试添加此内容:
div#netbar { position: fixed; top: 0; }
答案 2 :(得分:0)
div#netbar
{
position:fixed;
}
将位置的属性设置为固定可能会解决您的问题!
