我正在使用他们网站上的Bourbon SCSS / SASS导航菜单示例:http://refills.bourbon.io/(在此信息的底部粘贴代码,以便在波旁网站上进行编辑时保留)
我更改了SCSS代码中的第一行:
$navigation-padding: 1em;
说10em。
这导致导航项目10em向左移动。
当我进入firefox的下拉菜单时,一切正常 在chrome中尝试相同的东西,并且有一个非常有限的范围,将继续关注下拉菜单,如果你离开那个窄范围菜单消失(这在移动非常缓慢时)。此外,即使停留在窄范围内并沿着项目移动光标,下拉列表也会在第一项左右后消失。
如何让它在chrome中正常运行?
注意:是否有类似jsfiddle的方式来演示代码以便于编辑?
编辑:
我发现因为我在同一页面上使用了另一个例子,其中设备(某些智能手机)相对于其容器div而言超大,这导致菜单在chrome中消失。在Firefox中它工作得很好。它与.device类中的转换有关(我知道这是因为删除它会让它工作)。如果有人能找到解决方案,我会留下问题。
