我的网站上有固定菜单,没有任何问题。我有一个容器(不是引导程序),当与静态菜单联系时,它将被修复。一切都按预期工作,除非我重新调整窗口大小,容器进入0顶部的绝对位置。风格或任何内容都没有明确提及,因为它仍然有position:fixed
,但我看到的是这个。我在stackoverflow和其他资源中尝试了与此问题相关的大部分问题,但没有给我一个满意的答案。有帮助吗?感谢。

scrollTabs: function() {

jQuery(newElement).css(&#39; margin-top &#39;,&#39; - &#39; + elementHeight +&#39; px&#39;) ;
到
jQuery(newElement).css(&#39; 顶部&#39;,&#39; - &#39; + elementHeight +&#39; px&#39;); < / p>
