我有一个导航菜单，最多需要250px的页面左侧宽度和100％的高度。我添加了一个1.固定顶部标题列表项目在导航菜单的顶部，以及2.固定页脚列表项目在导航菜单的最底部。我的想法是保持这两项固定，并且当浏览器宽度达到一定大小时，这两个项目也必须消失。但我有一个很大的问题：固定宽度列表项扩展页面全长
问题1：当我固定宽度增加.topfilter和。 底部筛选器，列表项现在扩展了整个页面的整个宽度，而不是导航菜单。
问题2：现在，当我调整浏览器的固定宽度的项目 不会消失
奖励：我也不知道如何填充添加到.topfilter和.bottomfilter这样他们就不会掩盖前面的文字。 填充顶部和填充底部不起作用。
