  • Duplicated Selectors2
    .comment {} /* (2 times) */pre {} /* (2 times) */
  • Importants1

    Provides a way for a stylesheet author to give a CSS value more weight than it naturally has

    Avoid usage if at all possible. When you use !important, you’re disrupting the natural flow of your rules, giving more weight to rules that are undeserving of such weight

    td {height: inherit !important} 
  • Multi Classes Selectors1

    Selectors with multiple classes

    Unnecessary specificity, consider reducing to single class or id instead

    .rotate180.votearrow {}
  • Old IE Fixes1

    Rules specific to IE greater than or equal to IE 6 or IE 7

    Lower browser usage for previous versions of IE prevents these rules from being very useful

    .rotate180 {filter: progid:DXImageTransform.Microsoft.Matrix(M11=-1, M12=0, M21=0, M22=-1, DX=0, DY=0, SizingMethod='auto expand')} 
  • Old Property Prefixes6

    Properties with a no longer needed vendor prefix

    These have since been integrated or removed from mentioned browsers and can safely be removed from CSS

    .rotate180 { -moz-transform: rotate(180deg) } // was required by Firefox 15 and earlier .rotate180 { -o-transform: rotate(180deg) } // prefix is no longer supported .rotate180 { -ms-transform: rotate(180deg) } // was required by IE 9 and earlier .votearrow.rotate180 { -moz-transform: rotate(180deg) scale(1.3,1.3) } // was required by Firefox 15 and earlier .votearrow.rotate180 { -o-transform: rotate(180deg) scale(1.3,1.3) } // prefix is no longer supported .votearrow.rotate180 { -ms-transform: rotate(180deg) scale(1.3,1.3) } // was required by IE 9 and earlier 
  • Qualified Selectors3

    Since IDs are unique and classes are more unique than tags, adding a tag name would slow down the matching process needlessly

    Don’t qualify class or ID rules with tag names, as they are more unique than the tag. Strip tag names where possible

    span.pagetop {}span.pagetop b {}table.comment-tree .comment a {}
