    • No. You should combine individual class names using . : 

    .twelve-col.col.main-menu

    最有效的选择器将是nav.twelve-col.col.main-menu你也可以使用nav.main-menu ，这是有道理的。

    No. Your selector is trying to find main-menu INSIDE col which is INSIDE twelve-col . But you are looking for element, that has twelve-col col main-menu classes the same time, so use .twelve-col.col.main-menu

    However try BEM methodology, where you use just one class to make all your selectors same specificity (http://getbem.com)
