Use efficient CSS selectors

I get a score of F from gtmetrix

Here’s a few examples of many:

Very inefficient rules (good to fix on any page):

.header_right span.searchfor small – Tag key with 2 descendant selectors and Class overly qualified with tag

#menu-main ul.sub-menu li ul – Tag key with 3 descendant selectors and Class overly qualified with tag

.post-navigation a em – Tag key with 2 descendant selectors
